How one 105Ah lithium battery could completely change the way I use my campervan off-grid.

There are upgrades that make a campervan look better. ✨ There are upgrades that make it drive better. πŸ›ž Then there are the quiet upgrades hidden under a seat, connected by chunky cables, that fundamentally change what the van can actually do. This is one of those. Vanilla is about to get a Fogstar Drift 105Ah LiFePOβ‚„ leisure battery. πŸ”‹ And despite what the numbers initially suggest, I am not replacing a 110Ah battery with a slightly smaller 105Ah battery. Far from it. I am effectively giving Vanilla a much larger usable energy reserve, a stronger electrical backbone, better cold-weather capability, vastly improved voltage stability, Bluetooth monitoring and a battery that is far happier accepting power from my solar panel and alternator. This could be one of the most important upgrades I have made to the van. And considering Vanilla now sits on champagne-gold wheels wearing General Grabber AT3s, that is saying something. πŸ˜ŽπŸ›ž Welcome to the next stage of Project Vanilla. ⚑🚐

πŸ”‹ THE BATTERY Fogstar Drift 12V 105Ah LiFePOβ‚„ ⚑ 105Ah capacity ⚑ Around 1,280Wh stored energy ⚑ LiFePOβ‚„ chemistry ⚑ 100A continuous discharge ⚑ JBD Battery Management System ⚑ Bluetooth monitoring ⚑ Built-in low-temperature heating ⚑ IP67 protection ⚑ Around 10kg ⚑ 10-year warranty On paper that already sounds impressive, but the figures do not really explain why I am excited about it. To understand that, you have to look at what it is replacing.

πŸͺ« OLD WORLD: 110Ah AGM Vanilla currently has a conventional 110Ah AGM battery beneath the seat. It has done the job perfectly well. AGM batteries are proven, simple and reliable, but they come with one enormous limitation: you do not really want to use all of the capacity written on the label. A 110Ah AGM might technically hold 110Ah, but regularly taking it deeply discharged shortens its life. So campervan owners traditionally live by the old rule: ⚠️ try not to go much below 50%. That means my 110Ah AGM has effectively been treated more like a 55Ah working battery. In energy terms that gives me roughly 600 to 700Wh of sensible usable power. And suddenly the Fogstar starts looking very different.

⚑ 105Ah THAT BEHAVES NOTHING LIKE 105Ah The Fogstar stores around 1,280Wh. Lithium can comfortably use a far greater percentage of its capacity than AGM. I am not planning to drive it right down to BMS shutdown every night. That would be pointless. But using 80 to 90% is completely normal territory for LiFePOβ‚„. At 80% usable: πŸ”‹ about 1,024Wh At 90% usable: πŸ”‹ about 1,152Wh Compare that with roughly 600 to 700Wh from the AGM. So despite the sticker saying 105Ah rather than 110Ah, Vanilla could gain something like 55 to 75% more genuinely usable stored energy. That is the first big win. πŸ’₯ The important question is not: HOW MANY AMP-HOURS ARE PRINTED ON THE CASE? It is: HOW MUCH ENERGY CAN I ACTUALLY USE? And on that score, Vanilla has just grown a much bigger tank. πŸ”‹βš‘

🚐 VANILLA'S POWER ECOSYSTEM This is where things get interesting. Vanilla already has: β˜€οΈ 200W PV Logic PS-8688 solar πŸ”΅ Victron SmartSolar MPPT 75/15 πŸ”΅ Victron Orion Smart 30A DC-DC πŸ“Š Victron SmartShunt ⚑ Sargent EC155 ❄️ 50L compressor fridge πŸ”₯ Webasto diesel heater πŸ’‘ LED lighting πŸ“± USB charging πŸ“‘ 5G gear πŸŽ₯ cameras, drones and electronics Then there is the portable power side: πŸ”‹ Jackery 240 v2 πŸ”‹ Jackery 300d πŸ”‹ Jackery 1000 v2, Kindle πŸ”‹ Jackery 2000 v2, Forge Vanilla therefore does not really have one electrical system. She has an ecosystem. β˜€οΈ Solar supplies energy. 🚐 Driving supplies energy. πŸ”Œ EHU can supply energy. πŸ”‹ Fogstar stores energy. ⚑ Jackery handles the big 230V jobs. πŸ“Š SmartShunt tells me where it all went. The missing piece has been a leisure battery capable of properly exploiting everything around it. The Fogstar feels like that missing piece.

The missing piece has been a leisure battery capable of properly exploiting everything around it.

β˜€οΈ SOLAR JUST GOT A BETTER PARTNER During my three-week solar experiment I learned something very important: my 200W PV Logic panel works. Really works. I have seen: β˜€οΈ around 136W peak ⚑ around 9A charging πŸ“ˆ daily harvest ranging from tiny gloomy-day numbers to several hundred watt-hours Watching sunlight turn into usable electricity became strangely addictive. And now lithium makes that solar even more useful. AGM batteries become increasingly reluctant to accept current as they fill. Lithium stays much more enthusiastic for much longer. Think of it this way: πŸͺ« AGM = tap slowly closing as the tank fills. πŸ”‹ Lithium = tap wide open for much longer. That matters because British sunshine comes in bursts. One minute: ☁️ 18W Then: 🌀️ 74W Then suddenly: β˜€οΈ 136W Then: 🌧️ nothing. When the good solar arrives, I want the battery shouting: YES. SEND IT. ⚑ Not: I'll just have a little sip, thanks. The Fogstar does not magically produce more sunlight. It simply gives me a better place to put the sunlight I already collect.

πŸŒ₯️ BRITISH SOLAR IS ALL ABOUT OPPORTUNITY This is not Arizona. This is Britain. πŸ‡¬πŸ‡§πŸ˜‚ Cloud. Sun. Cloud. Rain. Grey. Different grey. One heroic patch of blue. Then rain again. So capturing the good bits matters. If the roof averages 100W for three decent hours: β˜€οΈ around 300Wh harvested. If I manage five decent hours: β˜€οΈ around 500Wh. That is a very meaningful chunk of a 1,280Wh battery. Vanilla does not necessarily need EHU to recover meaningful energy. She needs: β˜€οΈ sunlight ⏱️ time 🚐 and occasionally a drive.

🚐⚑ THE ORION 30A BECOMES A SERIOUS WEAPON Then comes my Victron Orion Smart 30A DC-DC charger. This takes energy from the vehicle while the engine is running and converts it into controlled leisure-battery charging. That is perfect for lithium. At roughly 30A and around 13 to 14V, we are talking in the region of 400W of potential charging power. That means an hour of driving can make a proper dent in what I used overnight. Two hours could replace a huge slice of a night’s consumption. And unlike solar, the Orion does not care if the sky is doing its best impression of wet concrete. So now the logic becomes beautifully simple: β˜€οΈ SUN = SOLAR 🚐 DRIVING = ORION πŸ”Œ CAMPSITE = MAINS πŸ”‹ PARKED = FOGSTAR ⚑ BIG 230V JOB = JACKERY That is no longer a pile of electrical gadgets. That is a proper energy strategy.

πŸ”₯ THE WEBASTO QUESTION This is the big one. Will the Fogstar make the Webasto better overnight? Electrically? Absolutely. Will it repair a faulty heater? No. If the Webasto has a mechanical problem, blocked burner, fuel issue or failed component, the battery will not perform miracles. But once the heater itself is healthy, lithium fixes one of the classic diesel-heater annoyances: πŸ“‰ VOLTAGE SAG. A diesel heater does not simply draw one tiny constant current. At startup: πŸ”₯ glow pin 🌬️ fan β›½ pump ⚑ electronics all wake up together. That creates a short, heavier electrical demand. An AGM can look fine at rest then sag hard under load. Lithium is much better at holding voltage steady. That means: πŸ”₯ Webasto starts ❄️ fridge starts πŸ’‘ lights stay bright πŸ“± USB stays happy πŸ”‹ battery voltage remains much firmer And that could make overnight heating feel far more dependable.

πŸ”₯ 13 VOLTS IS THE NEW NORMAL This is going to take some getting used to. With AGM, voltage is a rough state-of-charge gauge. As the battery empties, voltage gradually falls. Lithium behaves differently. It holds a relatively flat voltage for a long time. So hours after leaving full charge, I may still see a voltage that would have made the AGM look almost freshly charged. Then nearer empty, the voltage falls much more sharply. Which means: ⚠️ voltage alone is a rubbish fuel gauge for lithium. Fortunately Vanilla already has the answer: πŸ“Š Victron SmartShunt. And now I get another view: πŸ“± Fogstar Bluetooth BMS. So I will effectively have two live windows into the battery. One looking at everything flowing in and out. One looking inside the battery itself. This is going to be magnificent. I may never look out of the actual window again. πŸ˜‚πŸ“Š

πŸ“± TELEMETRY HEAVEN The Fogstar app should let me watch: πŸ”‹ State of charge ⚑ Voltage πŸ“ˆ Current βš™οΈ Charge/discharge status 🌑️ Temperature πŸ”’ Remaining capacity 🧠 BMS information Meanwhile Victron shows: β˜€οΈ solar watts ⚑ solar amps πŸ“Š daily harvest πŸ“ˆ historical performance πŸ”‹ SmartShunt SOC This means I can finally answer the questions I have been estimating for months. How much does the fridge really use overnight? How much does the Webasto genuinely use at 21Β°C? How much does lighting matter? How much does an hour’s driving replace? How much does a sunny morning recover? How much electricity does Vanilla actually need in 24 hours? That is gold. Because once I know the real numbers, I can stop guessing. And NIX loves numbers. πŸ“Šβš‘

πŸŒ™ THE FIRST BIG NIGHT TEST This is the test I am really looking forward to. Vanilla parked off-grid. No EHU. πŸ”‹ Fogstar charged ❄️ fridge running πŸ”₯ Webasto at 21Β°C πŸ’‘ normal lighting πŸ“± phone charging πŸ“‘ router running Then: 12 HOURS. No cheating. No turning the heater off at 02:00 because I am frightened of the battery voltage. No campsite cable. No external supply. Just Vanilla versus the night. Previously the AGM was always sitting there in the back of my mind: How low dare I go? Should I really leave the heater on? What happens at the next startup cycle? How much battery is really left? With lithium, the psychology changes. I can actually use the battery. That sounds obvious. But anyone who has lived with AGM knows exactly what I mean. Lead-acid makes you own a battery while constantly trying not to use too much of it. Lithium is there to work.

πŸ”₯❄️ FRIDGE + WEBASTO + LIGHTS Let’s use some realistic illustrative numbers. Suppose over a 12-hour night: ❄️ fridge averages 15W = 180Wh πŸ”₯ Webasto averages 20W = 240Wh πŸ’‘ lights = 40Wh πŸ“± phones/devices = 40Wh βš™οΈ miscellaneous = 40Wh Total: ⚑ around 500Wh. Against a 1,280Wh battery, that is only about 39%. Even if the actual night uses 650Wh: ⚑ that is roughly 51%. That still leaves a serious reserve. Then morning arrives. β˜€οΈ Solar wakes up. The battery starts receiving energy again. If the panel harvests 300Wh during the day, a 500Wh overnight deficit effectively becomes only a 200Wh net loss. Then I drive. 🚐 Orion joins in. Suddenly this is not really about: HOW LONG WILL MY BATTERY LAST? It becomes: CAN I REPLACE EACH DAY WHAT I USED THE NIGHT BEFORE? That is a much more interesting question.

♻️ ENERGY-NEUTRAL VANILLA This is the holy grail. The biggest battery is not necessarily the best system. The clever system is the one where production and consumption roughly balance. Imagine Vanilla uses: ⚑ 600Wh per day but gains: β˜€οΈ 350Wh solar 🚐 250Wh from driving Total back in: ⚑ 600Wh. The battery ends the day roughly where it started. At that point the Fogstar is no longer just a tank. It becomes a buffer. β˜€οΈ Energy arrives. πŸ”‹ Fogstar stores it. ❄️ fridge uses some. πŸ”₯ Webasto uses some. πŸŒ™ night passes. β˜€οΈ morning arrives. The cycle starts again. That is proper off-grid capability.

🌀️ THE LOVELY SUMMER VERSION Imagine this: 07:00 πŸ”‹ Fogstar 60% β˜€οΈ sun comes up 08:00 πŸ”₯ Webasto shuts down β˜€οΈ solar already producing 10:00 🚐 set off ⚑ Orion joins the solar 11:30 πŸ•οΈ arrive somewhere brilliant πŸ”‹ battery substantially recovered 18:00 🍳 Forge handles heavy cooking 20:00 πŸ’‘ lights on 🎡 music playing πŸ”₯ heater if needed 23:00 ❄️ fridge cold πŸ”₯ van warm πŸ”‹ battery healthy πŸ”Œ no EHU That is the dream. And now the hardware to do it actually exists.

🌧️ THE REAL BRITISH VERSION Of course then comes November. ☁️ grey 🌧️ rain ☁️ grey 🌧️ more rain 🌫️ mysterious dampness β˜€οΈ one confused photon at 14:17 Suppose solar only gives me 100Wh. Suppose Vanilla uses 650Wh. Net loss: ⚑ 550Wh. With around 1,100Wh of sensible lithium working capacity, I have roughly two days before I need meaningful replenishment. But then remember: 🚐 two hours driving can return hundreds of watt-hours ⚑ Jackery handles heavy loads πŸ”Œ EHU remains available when needed So the Fogstar does not have to power absolutely everything. It mainly has to run Vanilla’s native 12V systems. That is a much easier job.

⚑ JACKERY + FOGSTAR = VERY SMART COMBINATION Many people fit lithium because they want a huge inverter on the leisure battery. Induction. Microwave. Coffee machine. TV. Laptop. Everything. I do not need to. I already have Forge. ⚑ Jackery 2000 v2 = heavyweight 230V work ⚑ Kindle 1000 v2 = portable reserve πŸ”‹ Fogstar = Vanilla’s 12V heart So: 🍳 induction hob? FORGE πŸ”₯ microwave? FORGE ⚑ serious 230V load? FORGE ❄️ fridge? FOGSTAR πŸ”₯ Webasto? FOGSTAR πŸ’‘ lights? FOGSTAR πŸ“± USB? FOGSTAR That is beautifully sensible. Heavy loads stay away from the leisure battery. The Fogstar gets to concentrate on what it does best. It is almost like having: πŸ”‹ an engine room plus ⚑ an auxiliary power station. And that gives me huge flexibility.

βš–οΈ LESS WEIGHT, MORE POWER The Fogstar weighs around 10kg. A typical 110Ah AGM can easily weigh well over 20kg. So I am potentially losing somewhere around 10 to 20kg while gaining significantly more useful energy. That is brilliant campervan engineering. Less weight. More power. More usable capacity. Better charging. Better voltage. Normally upgrades make the van heavier. This one could actually do the opposite. And when Vanilla already carries: 🚲 Torque πŸ“· cameras 🚁 drones β›Ί awning πŸͺ‘ chairs πŸ’§ water 🍺 essentials and a box containing enough charging cables to rewire Birmingham, every kilogram matters. πŸ˜‚

🧊 COLD WEATHER READY The Fogstar also has integrated low-temperature heating. That matters because lithium does not like being charged while the cells are below freezing. The battery protects itself. If charging energy arrives while the battery is too cold, the heating system can warm the cells before normal charging resumes. That fits Vanilla perfectly. Imagine: πŸ₯Ά freezing morning 🚐 battery beneath the seat β˜€οΈ solar wakes or 🚐 engine starts Instead of blindly charging cold cells, the battery manages itself. For proper year-round campervan use, that matters enormously. Especially with Norway and Sweden lurking on the horizon. πŸ‡³πŸ‡΄πŸ‡ΈπŸ‡ͺ

🧠 THE BMS IS THE BOUNCER Inside the Fogstar is the Battery Management System. Think of it as an electronic bouncer. Too much current? 🚫 Not tonight. Too cold to charge? 🚫 Wait outside. Voltage getting silly? 🚫 Party over. Something wrong? 🚨 Shut it down. It monitors the battery and protects the cells from conditions that could damage them. That is a major step up from old-school AGM. The battery is not just storing energy. It is watching itself.

πŸ”Œ THE SARGENT EC155 QUESTION Vanilla still has the Sargent EC155. And I am happy with that. It handles: ⚑ distribution πŸ”§ fusing πŸ•οΈ habitation circuits πŸŽ›οΈ control But its built-in charger is old-school compared with a modern lithium charger. So I am not relying on the EC155 to be the clever part of the lithium system. That job belongs mainly to: πŸ”΅ Victron SmartSolar πŸ”΅ Victron Orion πŸ”‹ Fogstar BMS And, when needed, a proper lithium-compatible mains charging route. The important point is: GOOD LITHIUM INSTALLATION IS NOT: REMOVE AGM INSERT LITHIUM GO CAMPING It is: BATTERY + CHARGERS + SETTINGS + MONITORING. Everything needs to understand everything else.

β˜€οΈ THE VICRON SOLAR JUST GOT MORE IMPORTANT The SmartSolar MPPT 75/15 is programmable. That means I can set it properly for LiFePOβ‚„. No pretending the Fogstar is still AGM. No unsuitable lead-acid equalisation nonsense. Just sensible lithium charging. And then I can watch: β˜€οΈ PV voltage ⚑ PV current πŸ“Š daily yield πŸ”‹ charge state πŸ“ˆ history The beauty is that I already installed the good infrastructure. Now the new battery gets to use it properly.

🚐 THE ORION WAS FUTURE-PROOFING The same applies to the Orion. It may have looked like just another blue Victron box when it went in. Now it makes complete sense. Lithium batteries are capable of accepting high charge current. That needs managing properly. The Orion controls what comes from Vanilla's alternator. So: 🚐 alternator provides πŸ”΅ Orion regulates πŸ”‹ Fogstar accepts Everybody knows their job. And at 30A, driving becomes meaningful charging. That is ideal for the way I travel. I move. I explore. I stop. I move again. So the power rhythm becomes: 🚐 DRIVE ⚑ CHARGE πŸ•οΈ PARK β˜€οΈ SOLAR πŸŒ™ SLEEP πŸ”‹ DISCHARGE β˜€οΈ WAKE 🚐 DRIVE ⚑ CHARGE That is exactly what I want from Vanilla.

πŸ” LONG LIFE Lithium is also built for repeated cycling. Thousands of cycles are normal territory for decent LiFePOβ‚„. Even 3,500 full equivalent cycles would be more than nine years if somehow used every single day. And campervan use is rarely one full cycle every day. Some days: πŸ”‹ use 20% Some: πŸ”‹ use 40% Some: β˜€οΈ solar replaces what I use Some: πŸ”Œ EHU Some: 🚐 driving replenishes everything So realistically, this battery could be around for a very long time. That makes the economics much more interesting. Lithium used to be exotic. Now it is becoming the sensible choice.

πŸ“‰ VOLTAGE SAG: THE UPGRADE YOU DO NOT SEE This may turn out to be one of the best parts. AGM: ❄️ fridge starts πŸ“‰ voltage dips πŸ”₯ Webasto starts πŸ“‰ voltage dips more πŸ’‘ lights possibly change 😬 battery monitor looks unhappy Lithium: ❄️ fridge starts πŸ”₯ Webasto starts πŸ’‘ lights stay bright πŸ“± USB carries on πŸ”‹ voltage stays firm Nothing happens. And that is perfect. Boring electricity is good electricity. βš‘πŸ˜„

πŸ”‹ FROM BATTERY ANXIETY TO ENERGY CONFIDENCE This is perhaps the biggest change of all. With AGM I have spent ages thinking: How low is it? How far dare I go? Should I switch the heater off? Should I put it on EHU? Should I conserve? With lithium I can think differently: How much energy did I use? How much did solar replace? How much will driving replace? That is a much better way of looking at campervan power. Less anxiety. More engineering.

🌍 OFF-GRID SHOULD NOT MEAN MISERY There is a strange idea that proper off-grid camping means: πŸ’‘ lights off πŸ”₯ heater off πŸ“± stop charging ❄️ worry about fridge πŸ”‹ protect battery πŸ•―οΈ sit in darkness congratulating yourself on having 93% battery No thanks. πŸ˜‚ The whole point of the electrical system is to use it. I want: πŸ”₯ warm van ❄️ cold fridge 🍺 colder beer πŸ’‘ lights πŸ“± charged phone 🚁 drone batteries ready πŸ“· cameras ready 🎡 music πŸŽ₯ cinema β˜• coffee If I wanted the full 1847 experience I would buy a horse. The goal is not roughing it. The goal is making modern comfort sustainable. β˜€οΈ harvest energy 🚐 harvest energy πŸ”‹ store it πŸ“Š measure it ⚑ use it intelligently

β˜€οΈ WHAT CAN 200W SOLAR REALLY DO? Fogstar: πŸ”‹ 1,280Wh Panel: β˜€οΈ 200W rated In perfect fantasy-land: 1,280Wh Γ· 200W = 6.4 hours. Reality is different, obviously. Cloud. Heat. Panel angle. Season. Losses. Britain. My actual observed peak has been around 136W. At 136W: ⚑ 1,280Wh Γ· 136W = about 9.4 hours But the more useful example is this: If I use 500Wh overnight and average 100W solar the next day, that is around five good solar hours to put the same energy back. Now the 200W panel and 105Ah lithium battery start looking very well matched.

πŸ‡³πŸ‡΄ THIS IS WHY NORWAY GETS EVEN MORE EXCITING May 2027. Norway. Sweden. Long daylight. Cold nights. Regular driving. Remote stops. Photography. Drone flights. Big scenery. Lithium fits that type of travel beautifully. β˜€οΈ long daylight gives solar time 🚐 travelling gives Orion time πŸ”₯ Webasto keeps Vanilla warm πŸ”‹ Fogstar bridges the gaps 🧊 battery heating helps in low temperatures The best bit? If the system works properly, I should eventually stop thinking about it. Great engineering disappears into the background. I just use the van.

πŸ“Š THE NIX FOGSTAR TEST PROGRAMME Obviously I am not installing this and simply forgetting about it. That would be completely unlike me. πŸ˜‚ There will be data. Lots of data. Possibly deeply unnecessary quantities of data.

πŸŒ™ TEST 1 // THE 12-HOUR NIGHT πŸ”‹ full battery ❄️ fridge running πŸ”₯ Webasto at 21Β°C πŸ’‘ normal lighting πŸ“± charging Record: πŸ“Š starting SOC πŸ“Š ending SOC ⚑ Wh consumed 🌑️ temperature

πŸ•οΈ TEST 2 // 24 HOURS OFF-GRID Use Vanilla completely normally. No artificial energy saving. See what actually happens.

🌧️ TEST 3 // THE GREY DAY Proper rubbish weather. How much does 200W solar genuinely produce? What is the real net loss?

🚐 TEST 4 // DRIVING RECOVERY Start at a known SOC. Drive exactly one hour. Measure how much the Orion replaces.

β˜€οΈ TEST 5 // SOLAR RECOVERY Start at a known SOC. Park in decent sun. Measure exactly how much percentage and Wh return.

πŸ”₯ TEST 6 // FULL VANILLA Fridge. Webasto. Lights. Router. Phone. USB. Normal life. No babying the battery. That will give me something far more valuable than manufacturer claims: VANILLA DATA. πŸ“ŠπŸš

πŸ“ˆ SMARTSHUNT vs FOGSTAR This is going to be particularly interesting. Victron SmartShunt SOC versus Fogstar BMS SOC. Two independent views. One measuring the entire system. One measuring the battery from the inside. If they track closely: πŸ‘ brilliant If they drift: πŸ” investigate Either way, more information. For a data nerd this is basically Christmas morning with voltage graphs. πŸŽ„πŸ“ŠπŸ˜‚

πŸ›‘οΈ BUILT TO LIVE IN A VAN IP67 is reassuring too. Van interiors are not laboratories. They get: πŸ’§ condensation 🌑️ temperature swings 🌫️ damp 🧹 dust 🚐 vibration πŸ₯Ά cold β˜€οΈ heat So a battery designed with proper environmental protection makes sense. Mine is under the seat, not tied to the deck of HMS Londonderry in a North Atlantic gale, but I still like knowing it is built to handle real-world conditions.

πŸ”© 100A DISCHARGE The Fogstar can supply up to 100A continuously. At around 12.8V that is roughly: ⚑ 1,280W DC. That is miles beyond what Vanilla's normal 12V loads require. Which is good. It means huge headroom. But I do not need to abuse it. Forge already handles the heavyweight stuff. That means Fogstar gets an easy life. And electrical headroom is always welcome.

πŸ”‹ WHY 105Ah IS ENOUGH Could I buy a bigger lithium battery? Of course. 230Ah. 300Ah. 460Ah. Enough lithium to power a small principality. But bigger is not automatically better. Vanilla already has: β˜€οΈ 200W solar 🚐 30A DC-DC ⚑ Jackery reserves πŸ”Œ EHU capability ❄️ efficient compressor fridge πŸ”₯ diesel heating πŸ’‘ LED lighting So I do not need a gigantic battery. I need a balanced system. 105Ah gives me: πŸ”‹ about 1.28kWh βš–οΈ low weight πŸ“ compact size ⚑ high usable capacity β˜€οΈ good solar match 🚐 fast driving recovery Sometimes elegant beats enormous.

πŸŒ… WHAT I ACTUALLY EXPECT TO GAIN This is the important bit. I expect: πŸ”‹ MUCH MORE USABLE ENERGY Probably somewhere around 55 to 75% more comfortably usable capacity than the way I currently treat the AGM. πŸ”₯ MORE CONFIDENT WEBASTO USE Far less worry about startup voltage after hours of use. ❄️ FRIDGE CONFIDENCE Leave it running. That is literally what it is there for. β˜€οΈ BETTER SOLAR UTILISATION Make better use of good sunlight when it arrives. 🚐 FASTER RECOVERY 30A Orion charging becomes properly useful. 🧊 BETTER WINTER PERFORMANCE Battery heating and low-temperature protection. πŸ“± PROPER MONITORING Real battery information on my phone. βš–οΈ LESS WEIGHT Potentially dropping a significant lump of AGM weight. πŸ” LONGER LIFE Thousands of cycles. 😌 LESS BATTERY ANXIETY Perhaps the biggest upgrade of all. πŸ•οΈ MORE REAL OFF-GRID TIME Not theoretical time. Comfortable time.

🚐⚑ THE NIX VERDICT This is not really: 110Ah AGM β†’ 105Ah lithium. That makes it sound like I have gone backwards. What is actually happening is: πŸͺ« LIMITED USABLE CAPACITY β†’ πŸ”‹ DEEP USABLE CAPACITY πŸ“‰ SAGGY VOLTAGE β†’ ⚑ STABLE VOLTAGE 🐌 SLOWER ACCEPTANCE β†’ β˜€οΈ FAST ENERGY CAPTURE βš–οΈ HEAVY BATTERY β†’ πŸ”‹ LIGHTER BATTERY ❓ GUESSING β†’ πŸ“Š TELEMETRY 😬 BATTERY ANXIETY β†’ 😎 ENERGY CONFIDENCE Vanilla's power flow now starts to look beautifully simple: β˜€οΈ SUN β†’ VICTRON MPPT β†’ FOGSTAR 🚐 ENGINE β†’ ORION 30A β†’ FOGSTAR πŸ”‹ FOGSTAR β†’ FRIDGE πŸ”‹ FOGSTAR β†’ WEBASTO πŸ”‹ FOGSTAR β†’ LIGHTS πŸ”‹ FOGSTAR β†’ VANILLA πŸ“Š SMARTSHUNT β†’ DATA ⚑ JACKERY β†’ BIG STUFF That is a proper little off-grid ecosystem.

🌌 THE FIRST NIGHT One day soon Vanilla will be parked somewhere quiet. Maybe Cannock Chase. Maybe Scotland. Maybe Norway. Maybe a campervan field somewhere with absolutely no EHU. Outside: 🌌 dark sky πŸ₯Ά cold air 🌲 silence Inside: πŸ”₯ 21Β°C ❄️ cold fridge 🍺 colder beer πŸ’‘ warm LEDs 🎡 music πŸ“± phone charging No orange EHU cable. No campsite bollard. No staring nervously at 12.1V. Beneath the seat, around ten kilograms of lithium, copper, electronics and chemistry will quietly keep the whole van alive. Then morning comes. β˜€οΈ sunlight hits the PV Logic panel πŸ”΅ Victron wakes up ⚑ watts start flowing πŸ”‹ Fogstar starts climbing πŸ“Š graph starts moving And yes, I will absolutely be watching it. Obviously. This is NIX Drones. We don't merely go camping. We collect telemetry from it. πŸ˜‚πŸ“ŠπŸš
