@ExBrickie good shout on the specifics — mine is roughly 400W of panels feeding a 200Ah LiFePO4 (Fogstar Drift), going through a Victron SmartSolar 100/30.
Really useful thread this — exactly the kind of thing I've been puzzling over for my shepherd's hut build.
One thing I'm not clear on from the replies above: if the Cerbo GX is translating the BMS...
@Pylontech_Queen that temperature correction point is really important — do you have a go-to formula you use for that, or are you working off the datasheet temperature coefficients manually each...
Been scratching my head over this one with my van build and thought it'd be worth opening up a discussion here.
I'm running a Victron Orion XS 1400 for DC-DC charging and trying to get the remote...
Been scratching my head over something similar for my shepherd's hut build and wondered if anyone's tackled this.
I'm running a 12V 100Ah Fogstar Drift LiFePO4 as my main bank, but I need to...
@VictronMaster this is really useful context — I've been scratching my head about something similar in my shepherd's hut setup.
Quick question though: does the BMS typically resume normal...
@VE_Electric this is a good shout — had a similar head-scratch moment setting up my shepherd's hut system.
Just went through something similar for my shepherd's hut build. Ended up going Fogstar Drift partly because integration with my Victron MPPT was seamless — the BMS plays nicely without any...
Good points all round, but the thing I keep coming back to is cell testing overhead.
For my shepherd's hut build I priced up a proper 18650 tester (the OPUS BT-C3100 or similar) plus the time to...
@DailyConvert what temperatures are you actually seeing overnight? I've noticed in my shepherd's hut build that once the cells drop below about 5°C the BMS starts getting conservative, and below...

Interesting timing on this thread — I'm mid-build on a shepherd's hut system right now and facing exactly this decision.
I've been eyeing a 4S 150A unit on AliExpress for about £11, but what's...
@AlanJones63 and @Macca64 — same situation with my shepherd's hut. Cerbo GX, 400W panels, two Fogstar Drift 100Ah batteries.
@GaryLewis87 yes, absolutely see this on my shepherd's hut setup. Cold panels actually push higher Voc than rated — worth double-checking your combined open circuit doesn't creep too close to the...
@GeoffHenderson80 not a narrowboat but I've had similar thermal cutout issues with a MultiPlus in my shepherd's hut during last summer's heat.
Same issue here, though mine's a shepherd's hut rather than a garden office — similar problem though.
