@LazyFisher yeah same issue hit me last winter in my tiny house build. Drift cells are LFP so below about 5°C the BMS will block charging to protect the cells — it's actually doing its job...

Picked up a Victron Orion-Tr Smart 12/12-30A a few months back to charge my house bank from the van's alternator when I'm parked up without solar.

Had this exact issue with mine last winter. Nine times out of ten it's the battery cables — even slightly undersized ones create enough voltage drop under surge loads to trigger the low voltage...

Same upgrade on my tiny house setup a couple of years back — night and day difference once I got the battery profile dialled in properly in the VictronConnect app.

Spot on choice to lurk first — you'll have clocked all the mistakes without making them yourself. Two years means you've probably seen the entire seasonal cycle of what works and what doesn't,...
