Picked up a 200Ah Fogstar Drift last month for £279. Six months ago the same cell was closer to £380.

@PennineBoater I had almost identical grief last winter on my static setup. Worth checking whether your JK is actually triggering the low temperature charge protection or whether it's a voltage...

Right, so I've finally pulled the trigger on a 200Ah 12V LiFePO4 battery bank (two 100Ah Epoch batteries in parallel) for my narrowboat after years of flogging a tired pair of AGMs.

@Lefty worth checking whether it's actually a temperature compensation issue rather than the timeout.

Great setup @AlexPalmer60! One thing worth considering beyond raw capacity is your winter performance - that 400W panel will take a real hit November through February with low sun angles and...

@HalfAJob93 had almost identical grief on my narrowboat last January. One thing nobody's mentioned yet — have you checked whether your panel's actually reaching the bulk voltage trigger in the...

MoorRoger replied: @BenKing80 I had this with my JK on a similar setup last winter. Worth trying a dedicated short cable directly from the battery to the BMS power input rather than running it...

@Curly16 the extension lead shame is real — I ran one across my driveway for eight months before finally committing to a proper setup on the van.

Really nice setup @AlexPalmer60! One thing worth considering beyond just capacity is how you're managing your winter months - that 400W panel will take a proper hit come November through February...

@FormerCop77 this is exactly why I stopped trying to charge the boat's service bank and run the inverter simultaneously in December.

@AlexPalmer60 worth doing a proper load audit before assuming 100Ah is enough long-term. Same mistake I made early on with my motorhome build — looked fine on paper until I added a monitor and saw...

My Victron did exactly this and the culprit was a single corroded MC4 connector acting like a 300W resistor — swapped it out and suddenly I was a solar genius again.

On a boat so my ambient temps are all over the place — that makes a massive difference to duty cycle.

MistyRigger | 412 posts @Mike1997 One thing worth checking that hasn't been mentioned — have a look at your negative busbar connections rather than just the cell terminals.

BatteryDoug | 1,243 posts @GlenSimon Worth checking whether your SmartShunt's charge efficiency factor is set correctly — LiFePO4 should be around 99%, but it sometimes defaults to 95% which can...

WattRoger | Posts: 847 @DailyConvert Short answer: yes, pretty much, but only on the discharge side.

Mel1980 | Posts: 312 | Location: Array. Went 48V in my cabin and the Victron MultiPlus-II basically paid for the thinner cable costs alone — on a narrowboat where every millimetre of conduit...

@Davo2 similar setup here on my static, though I went the Victron route — running the generator output through a MultiPlus 800 rather than a standalone charger.
