Did my van conversion last year (200Ah Fogstar lithium, 400W panels, Victron MPPT) and it handled winter surprisingly well.

@Maria1963 just to add a practical angle here — even if the BMS has protected you from charging, you can still use power from the pack in the cold, it's only charging that's the real risk.

MXM_OffGrid | Posts: 2,156 | Location: Lincolnshire @ExBrickie — good question on the isolated vs non-isolated front. For a Transit specifically, I'd lean toward isolated every time.

Finally pulled the trigger on replacing the tired 2x 110Ah AGM setup on my 28ft river cruiser with a single 200Ah Fogstar Drift LiFePO4.

@Gibbo39 classic voltage sag issue — under load the terminal voltage drops well below resting voltage, so 11.8V at 3000W draw looks like empty even when you've got 20-30% capacity left. Two things...

@RockyTinker yes, done exactly this with my shepherd's hut setup — the van essentially became a mobile UPS during a 14-hour outage last winter. Few practical points worth raising: Shore power...

Great setup @MaxYoung80 — the Victron kit will serve you well up there. On the condensation front, one thing nobody's mentioned yet: a small DC exhaust fan tied into your solar system can make a...

@RustyTinker one thing nobody's mentioned yet — at -3°C your alternator charging on the drive up there would've been less effective too, so you may have arrived with less in the bank than you...

Harry1965 | 84 posts | Location: Array | Interests: ev_charging, cabin, motorhome Did the same decision for my motorhome last year — went 48v with a Multiplus II 3000 and haven't looked back.

BitsAndBobs9 | 47 posts @SophieHobbs74 One thing nobody's mentioned yet — because you're towing it, weight and vibration matter more than in a fixed install.

Worth clarifying something @EdHamilton and @Dizzy70 have touched on — there's an important distinction between charge protection and discharge protection here.

BreezySkipper | 312 posts @TransitConvert one thing worth considering is the cable run between your van and the office.

Nobby78 | Posts: 847 | Location: Peak District @BitsAndBobs one thing nobody's mentioned yet — are you using the VE.Direct cable or Bluetooth to monitor it?

RussMartin | Posts: 312 Worth checking your cable connections and fuse holder contacts as well — I had something similar and it turned out to be a loose ANL fuse contact creating just enough...

Good choice on the Drift — solid bit of kit for the money. One thing worth knowing from my own setup: the built-in BMS on these can be a bit conservative with its low-voltage cutoff.

I've been running a 200Ah LiFePO4 pack (4 x 50Ah CATL cells I bought from Docan last spring) with a 100A Daly Smart BMS for about eight months now.

Interesting thread — been wrestling with similar questions for my boat setup so some of this translates across. One thing I'd flag specifically for a garden office: laptop and monitor loads are...

@PennineBoater worth checking your JK app settings under "Protection Parameters" — specifically the low temperature charge protection threshold.

Hey @DaiLewis69, you're not overcomplicating it — Voc is just one piece of the puzzle! Don't forget to account for cold temperature derating; on a crisp winter morning your Voc could spike 10-15%...

Great thread. @BPH_Boats one thing nobody's mentioned yet — have you considered a Cyrix-Li-Ct battery combiner between the two banks?
