Good timing on this thread — I ran almost the same combo in my Ducato for about six months before making a decision. The thing worth considering that nobody's mentioned yet is alternator load...

FX_Power | 89 posts One thing nobody's mentioned — keep an eye on how they self-discharge when sat idle. Dodgy second-hand units can lose meaningful capacity overnight even with nothing connected.

Great topic @Gibbo39. One thing worth trying before you give up on any stubborn cells — do a very slow top balance at 3.65V per cell using a bench power supply, keeping current down to around...

Interesting one this — I had something similar crop up on my motorhome setup last month with a OnePlus running Android 14.

@WendyLewis I had exactly this with my setup last winter. Worth checking whether your temperature sensor is actually making good contact with the cells — mine had worked slightly loose and was...

DaiWalker61 | 412 posts Good shout from @KN_Builds on sensor placement — I'd extend that and say also check which temperature sensor the JK is actually using to trigger the low temp cutoff.

TransitNomad | Posts: 847 | Location: Canal network, somewhere near Middlewich @OffGridTel for a narrowboat I'd honestly push you toward 48V without much hesitation.

Moored up on the Shrewsbury canal last January, minus four overnight, and I woke to a completely dead boat. No inverter, no heating fan, nothing.

LDVConvert | 412 posts | Array The panel-to-battery ratio is worth scrutinising here. 400W feeding a 200Ah bank is actually reasonable sizing, but your real constraint is the 100/30 MPPT — that's...

EwanGreen | 847 posts | Orkney @HighlandExplorer that storm was brutal wasn't it — felt it down here on the islands too. My rule of thumb for a Scottish winter three-dayer: I won't feel...
KangooWanderer | 1,203 posts | 🚐 Converted Kangoo + Narrowboat @ForestDweller I'm literally in your exact situation — Kangoo camper and a 57ft narrowboat, both running LiFePO4.

I've had a Victron Orion-Tr Smart 12/12-30 running between my van starter battery and a 100Ah lithium leisure battery for about six months now.

Hey @JackieScott, something nobody's mentioned yet — have you checked whether there's any shading creeping in during winter that wasn't an issue in summer?
FZ_Builds | 312 posts @PU_Sparks The JK BMS SoC readout is honestly decorative at best — treat it as a rough guide rather than gospel.

Updated mine to the latest firmware last night (v4.12) and now the state of charge is all over the place.

Slapped a small turbine next to my panels last autumn and honestly the thing earns its keep on every miserable grey day that would've left my Fogstar batteries looking sorry for themselves —...

@KevLee nice one — I went down a similar rabbit hole last year with a Renault Zoe pack. Ended up with six modules running in my old Hymer, giving me around 14kWh usable after I'd set conservative...
