Tommo | 2,341 posts @SprinterWanderer Worth adding some nuance here — your Renogy panels almost certainly have bypass diodes built into the junction box (usually three per panel, protecting cell...

Great write-up @MasterSolar, looking forward to the full details. I made a similar swap on my narrowboat two seasons ago and the usable capacity difference alone was worth every penny — you're...

TonyRoss | 412 posts @PU_Sparks One thing nobody's mentioned yet — the JK BMS SoC is heavily dependent on having your cell capacity set correctly in the app.

On the narrowboat I learned the hard way that thermal mass works against you when things heat up — the cells themselves become a radiator.

Been pulling my hair out with this one. I've got a 4S 280Ah LiFePO4 pack (EVE cells) paired with a JK BMS-8S20P, wired up in my converted Sprinter alongside a Victron MPPT 100/30 and a B2B charger...

Been running a 280Ah LiFePO4 pack (four EVE cells in a 12V config) in my narrowboat over winter and I've had the JK BMS cut out on me twice now when temperatures dropped below about 4°C in the...

@MasterCamper this one caught me out badly during the Beast from the East a few years back — woke up to a completely dead system because the BMS had done exactly what it's supposed to do and I'd...

Finally pulling the trigger on a proper off-grid setup for my 4x3m garden office. I've been running a long extension lead from the house for two years and I'm sick of it.

Been following this thread with interest. One thing I'd add that hasn't been mentioned yet — have you tried putting a proper capacity tester on them rather than relying on the BMS readout?

@Paul1975 Done exactly this for my static caravan backup setup. The bit people overlook at your budget level is the charge controller — don't scrimp there.

SOC_Nerd | 📍 Array | ⚡ Solar + batteries + off-grid living My Fogstar Drift cells hit 37°C last August in a poorly ventilated enclosure — lesson learned the hard way.

Great shout from @LutonCamper on the Orion-Tr Smart — that's exactly what I'd recommend too. The big advantage nobody mentions is that the DC-DC charger will actually deliver a proper multi-stage...

Hey @AlexPalmer60, similar setup here but I went slightly bigger after underestimating my loads initially. Running a 600W array through a Victron 100/30 into a 200Ah Fogstar Drift.

SomersetBoater | 847 posts @KevLee great write-up, and honestly that Fogstar Drift is a solid shout for the money — I've got one running on my narrowboat and it's been faultless for coming up on...

MultiPlusGeek | Posts: 312 @IslandVanLifer The clue's in my username — have you considered a Victron MultiPlus-II as the heart of your system?
Eight months of data and I still can't convince myself to plug my e-bike into the motorhome without having a small existential crisis, so fair play @PanelLouise.

Been scratching my head over this for a few weeks now. My garden office setup currently runs four 200W 24V panels wired in two parallel strings feeding a Victron SmartSolar 100/30, which handles...
