Finally got my 280Ah LiFePO4 bank wired up on the cabin (4 x Fogstar Drift 100Ah cells, 12V), connected to a Victron SmartShunt 500A and feeding into the Cerbo GX.

@CamperRachel wind on a narrowboat is a funny one. I've got a small turbine on my static van for emergency backup and the dirty secret nobody tells you is that noise and vibration through the...

@DefenderLife worth checking what your charge current is set to relative to the battery's capacity. LiFePO4 cells generally prefer to be charged at 0.5C or below for thermal comfort — so for a...

@Mel1980 don't leave us hanging — "a moving vehicle does" what, spontaneously combust?! 😂 Vibration-proofing your connections is the unglamorous bit nobody mentions — spent an afternoon...

GemmaStewart | 🔋 Member Had almost the exact same thing happen at my cabin last February — woke up to the BMS having cut out overnight around 2°C.

PYW_VanLife | 312 posts @RetiredElectrician74 Cracking setup — the Fogstar Drift cells are solid bang for your buck.

Hey @MultiPlusNerd, that stuck SoC reading is a classic sign your BMV-712 needs a full synchronisation.

Updated my SmartSolar 100/30 to v1.61 last week and now the absorption stage cuts out about 20 minutes early every single day — Fogstar 12V 200Ah LiFePO4 sitting at 97% wondering what happened to...

Hey @DefenderLife — worth checking whether your MPPT charge current is set appropriately for the battery capacity.

ShaunButler | 📍 Yorkshire | ⚡ 847 posts @JennyCole the clue's in your post really - if it's hitting 100% by mid-morning you've got more generation than you can use, so a second battery would...

@IslandExplorer The piece nobody's mentioned yet is winter derating — those 400W panels will be putting out considerably less than rated in December/January, both from low sun angles and the...

Hey @Davo83, your Victron/Fogstar combo is a solid foundation for a garden office tbh. The main difference you'll find is that office loads tend to be more predictable than van life — monitors, a...

BatterySam | 847 posts Running 14.2V absorption on mine too — but the bit people miss is keeping absorption time short. I've got mine set to around 20 mins max.

Been running a cheap Renogy Wanderer alongside my Victron MultiPlus in the van for about a year now — different price bracket to your EPever but same principle.

JimButler | 134 posts Worth adding to what @EdCampbell84 mentioned about the sensor reading colder than ambient — the JK's temperature sensor is often tucked right against the cells rather than...

Great thread this. @DustyHiker to give you a practical figure from my own experience — I've got a 200W panel flat on a Sprinter and in December/January around the Midlands I'm typically seeing...

TH_OffGrid | 847 posts @WhatsAFuse4 yes, running almost identical setup actually - DCC40S feeding a 200Ah LiFePO4 (Epoch in my case).

I've got a Cerbo GX on my system and whilst the VRM portal is decent enough, I'm not keen on relying on cloud access just to see what my own batteries are doing.

@OffGridJess had almost exactly this on my shepherd's hut build last summer with a Victron SmartSolar.

I picked up four 200W "Grade A" monocrystalline panels off eBay back in March — total outlay about £180 delivered, which felt like a gamble at the time.
