A lighting was strike but fuse failed and the felicity 48v 5kwh battery is not powering on.but the inverter is fine.any suggestions? Is it bms?
Good shout from @Fiona1974 on the reset — but with a lightning strike involved, I'd go a step further before assuming it's just a tripped BMS. What I'd do first: Measure the actual cell voltage...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
Great points all round. One thing worth adding from my own experience running a 200Ah Fogstar Drift LiFePO4 in the van — the Daly's SOC will drift badly after partial cycles if it never sees a...

Battery Balancer rapid alarm on/off switching
@PennineNomad's cut-off post was probably heading somewhere important — I'd bet they were about to mention internal resistance mismatch. Had this exact hunting behaviour on my motorhome build...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@MelKing83 ran this exact scenario last winter when I was testing backup power for my motorhome conversion.

Feedback wanted: free tool that sizes battery/solar/inverter/wiring for a 12V camper build
Been playing around with this over the weekend whilst finalising the wiring spec for my van build and I have to say it's genuinely useful — particularly the wiring sizing section, which is where...

How can the battery be woken up and charged by the SmartSolar MPPT？
Good shout from @GoldenTrekker on the threshold point. One thing nobody's mentioned yet — if the pulses genuinely aren't working and you're in a hurry, a small donor battery temporarily paralleled...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Been through exactly this with my van build last spring. Had a Fogstar Drift 200Ah LiFePO4 paired with a BMV-712, and the two were regularly disagreeing by 8-12% — maddening when you're trying to...

Question about new solar configuration on board
@Midge three years liveaboard means you know your consumption patterns better than most — that's actually your biggest advantage when redesigning a system. The one thing I'd add to what's been...

Off grid bluetti ac500 with roof mount solar panels
@Fiona1974 good call on the Victron/Fogstar route for the hut. I ran a Bluetti EB series unit as a trial before committing to my van build, and the closed ecosystem genuinely bit me — wanted to...

Mppt as a dc to dc charger
Good topic — this came up when I was wiring my motorhome's secondary battery bank a few years back. @CaddyProject has touched on the key issue: without a proper varying-voltage input (like a solar...

12 volt battery with 300 amp bms
Been down this road a few times now — first on my van build, then again when I put together an emergency backup system for the narrowboat. The BMS rating is honestly one of those things people...

Orion XS shown as non-BMS-managed
Good shout from @DevonDweller on the passively-vs-actively managed distinction — that caught me out on my own van build last spring. One thing nobody's mentioned yet: firmware version matters...

Growatt SPF 6000 ES + Pylontech US2000c battery BMS comm
Good shout from @VoltKev on the LIb setting — just to add, once comms are established the Growatt should display the Pylontech's SOC on the LCD.

Insulating a stone bothy – worth doing the floor or just walls and roof?
@ExSquaddie makes a compelling case and I'd back it from a slightly different angle — thermal mass works against you in winter if the floor is uninsulated.

Anyone else using a Raspberry Pi to log their battery data long-term?
@ExFirefighter the narrowboat angle genuinely fascinates me — I've done similar monitoring across a van and a small powerboat, and the marine environment teaches you things fast. One thing...
