Great timing on this question — I went through exactly the same deliberation before fitting a MultiPlus 12/3000 in our converted horsebox last spring.

Yes, had almost identical with my Drift pack last February! The BMS was throwing low-temp protection errors around 4–5°C which is actually it working correctly — LiFePO4...
Really useful thread this. Just to add something I haven't seen mentioned yet — when you're running the EU22i to top up your LiFePO4, it's worth thinking about when you run it rather than just...

I've been running a Victron SmartSolar 100/30 with two 200W panels on the roof of my static and I've noticed my 200Ah lithium bank is sitting noticeably lower every morning than it should be after...
