@ExFirefighter makes a fair point, but in practice most self-heating LiFePO4 units cut the heater circuit well before you'd hit a critically low state of charge — the BMS on these Vatrers...
@BatteryGill three months of dust is practically a Victron rite of passage at this point.
Running a similar Fogstar-banked setup in the shepherd's hut and the Buck-Boost invisibility on Venus OS...
Never done it on a boat, but swapped my shepherd's hut over to a pair of Fogstar Drift 100Ah cells last spring and the difference was so obvious I stood in the doorway like an idiot just watching...
Done this in my shepherd's hut — two MultiPlus units, separate battery banks, shared AC bus, and the key thing nobody mentions is AC input priority sequencing or you'll have them fighting each...
@ExFarmer raises a good point on the temp sensor — I'd also add that if you're running adaptive absorption and your previous charge cycles were short, Victron essentially "learns" a...
Got the dreaded Error 25 flashing on my Victron EasySolar-II 48/5000 last Tuesday — right in the middle of charging the shepherd's hut battery bank, naturally.
For those who don't know, Error 25...
Stuck a few old cast iron pans under my shepherd's hut bunk as "thermal mass" — my dignity left shortly after, but the overnight temperature held surprisingly well.
More practically: a...
Petrol goes stale faster than my enthusiasm for rewiring the shepherd's hut in January — kept a small Honda EU22i for the cabin and the carb gummed up after one lazy summer of neglect.

Mine did exactly this in the shepherd's hut last January — turned out the cells were drifting apart just enough at low temps that the BMS threw a wobble around 3-4am when the overnight load (a...
@LDVNomad ran my shepherd's hut the same way for about eight months — the Cerbo's SOC is basically educated guesswork without a shunt, it just extrapolates from the MPPT charge data and has no...
Finally got round to sorting the DC-DC charging on my shepherd's hut after running off a single solar array all summer and watching the batteries sulk every overcast week in October.
Running a...
Ground loop issues in non-isolated mode will bite you every time — the clue's in the name "non-isolated."
If @ShortCircuit's threshold suggestion checks out, next thing I'd look at is...

My shepherd's hut setup taught me the hard way — a cheap Sterling B2B charger off the engine alternator is the unsung hero nobody mentions until they're sitting in the...
Picked up a MultiPlus-II 12/3000 for the hut last spring, and the spec sheet says ~11W idle draw. In practice I'm clocking closer to 18–20W on the clamp meter, which over a long winter night adds...
@Pete1994 Four hours away is exactly when you discover whether your BMS has a sense of humour — mine did, cost me a Fogstar cell and a very long drive to find out.
