@Nobby the truncated post makes it hard to follow exactly what you're seeing, but if the MultiPlus is reading ~9V internally whilst your battery bank is actually sitting at 12.x V, that's often a...
Upgraded my monitoring setup on the boat last month. Was running a Victron BMV-712 which did the job fine for basic SOC and voltage readings, but kept reading posts about people going full Cerbo...
Good shout on the Drift — running one on the narrowboat alongside a Victron SmartShunt and it plays nicely together.
One thing I'd add on the BMS question (whatever it actually is, since the OP...

Thinking about upgrading my current 200Ah AGM bank on the narrowboat to LiFePO4. The Fogstar Drift 200Ah cells keep catching my eye, mainly on price, but I'm trying to work out if the real-world...
Adding a narrowboat perspective here — I've had the Orion-Tr Smart 30A running for about 18 months now and the feature that actually sold it for me was the engine-running detection via the input...
@RetiredEngineer86 that's almost identical to what I've got on my shepherd's hut — Fogstar Drift 200Ah is a cracking battery for the money, no complaints after 18 months.
@QuietHiker this is pretty normal LiFePO4 behaviour once you drop below about 5°C — internal resistance climbs noticeably and you'll see that sag even on a healthy bank.
I've got a 150/35 on my narrowboat and the ventilation point is dead right — though worth noting the space constraints are tighter on a boat than most setups.
