Really useful thread — lurking on this one hard as I'm in a similar position with a static tiny house build. Quick question nobody's addressed yet: what's your actual shore power supply like on...

Hey @DustyCaptain — worth considering your actual use case here. The 18A will push roughly 216W into that Fogstar, which on a decent run should recover a good chunk of capacity fairly comfortably.

Gazza75 | 312 posts | 🔋 12v → 48v convert @CamperAndrea cracking find! I've been running a 2014 Leaf pack for about 18 months now, similar vintage to yours.

I've been down a bit of a rabbit hole lately looking at repurposed Nissan Leaf gen 2 battery modules for a home backup setup.

@IvyWalker raises a genuinely interesting edge case. I ran both simultaneously for about three months when I was mid-build on my shepherd's hut backup system — basically while I was still figuring...

Eight months in and still going — Fogstar Drift paired with an Orion-Tr Smart is basically the "just works" combo that makes the rest of us look like we're overcomplicating things. One...

Right, so about eight months ago I took the plunge on a budget battery system for the shed after a particularly grim power cut that left us without anything useful for 14 hours.

@IanWhite curious whether you've actually confirmed the Cerbo's local SD card is logging continuously during those dropouts, or are you assuming it is?

Harry1965 | 147 posts | ⚡ Practical Off-Gridder Done this exact swap on my cabin setup. The wiring faff is real but honestly the thicker 12v cables were more hassle long-term — every connection...

The Fogstar BMS is the last line of defence — let it do its job while you set the Victron to something slightly conservative (I run 14.2V absorption, 13.5V float in my motorhome setup and the...

@FormerMariner24 ran almost identical kit on the narrowboat for two winters before I got fed up with the constant anxious glances at the Cerbo whenever someone so much as thought about using the...

I've got a MultiPlus 12/3000/120 in my narrowboat and it's developed an annoying low hum when it's connected to shore power and just sitting in charge/passthrough mode.

Hey @DebbiePowell76! One thing worth checking that I don't think anyone's covered yet — make sure your BMV-712's "charged voltage" threshold is set correctly for lithium.
