@Scouse one thing nobody's mentioned yet — warranty and returns. If those Amazon cells turn a bit rubbish six months in, you're likely dealing with a Chinese seller who'll ghost you, or at best a...

@Paddy78 done exactly this on my old widebeam a few years back. The weight saving alone is worth it — AGMs are brutal on older boats with dodgy waterlines. One thing people don't mention enough:...

@Rob1968 solid thread. Running a Pi 4 on my garden office setup with Victron MPPT and a Fogstar 100Ah LiFePO4, and the one thing I'd add beyond what's already been mentioned — get your data into...

@LDVNomad the van-to-home translation absolutely works — I stumbled into exactly this realisation during a road trip planning session when I noticed my motorhome's backup circuit was more reliable...

Fitted two Fogstar Drift 200Ah batteries in a vented under-floor box last autumn — seemed dead clever at the time.

ValleyAmy | 412 posts | 🔋 Off-Grid Enthusiast @MelKing83 As @BazLewis72 suggests the BMS logs are a good starting point, but also worth bearing in mind that LiFePO4 cells genuinely do lose usable...

@VanBarry had a relay on my cabin's backup charging circuit for a while — the hidden killer for me was voltage drop under load masking the actual charge state.

@ExTrucker63 familiar situation here. My setup mixes Victron MPPT and inverter/charger with a Fogstar Drift bank — the Fogstar's BMS doesn't communicate natively with the Cerbo obviously, so I'm...

Been scratching my head over this one for a few days now. My MultiPlus 24/2000 keeps cutting the bulk charge short and jumping straight to float when the batteries are nowhere near full — we're...

@Trevor1986 interesting timing on this — just went through similar with a Sprinter build last year. One thing that catches people out with Victron BMS setups is the load disconnect behaviour.

@12VNerd one thing worth watching with that combo — the DCC40S and a Victron MPPT can occasionally "argue" over the battery if your BMS starts load-shedding.

@Davo22 yes, running a Honda EU22i alongside my shepherd's hut solar setup (800W panels, 200Ah Fogstar Drift) and it's genuinely transformed winter resilience.

@StuThompson had almost identical behaviour with my garden office setup last winter. Turned out my cell internal resistance had drifted unevenly across the four cells — the JK was seeing one cell...

@ExpertCamper Worth thinking about what your actual worst-case daily consumption looks like rather than just the total bank size.

HelenLewis | 1,203 posts | Peak District @CumbrianExplorer Worth noting that even once you've adjusted the low-temp threshold in JK's app, you're really just telling the BMS to permit charging at...

Great points from @BoxerCamper and @Gibbo already. One thing worth adding - even if you were tempted to try isolating them with a battery-to-battery charger (B2B), you'd essentially be treating...

BazLewis72 | 847 posts | ⚡ Solar Addict @MelKing83 Worth checking your JK BMS logs for any low-temperature cutoffs over winter — the JK will throttle or disconnect charging if cells drop below a...

SueThompson99 | 156 posts @ROW_OffGrid I ran mine at 14.2V absorption for about six months and was perfectly happy, but recently dropped it to 14.0V after reading some discussion about cycle...

@BrookRunner the flat voltage curve issue @ExBrickie mentions is real, but I'd also check your charged voltage and tail current settings in the BMV.
