Slightly odd post to land here given this is a UK forum and the job's in French/PACA region, but the underlying question is interesting regardless. We went down a similar route for my garden...

Had something similar happen with my Victron setup last year — not a Quattro but a MultiPlus-II 48/5000, so slightly different beast, but the same kind of sinking feeling when a firmware update...

@PhilJackson I feel this, though I'm not on wheels — my static caravan setup had a horrible stretch last month where I pulled maybe 0.3kWh over three days from the panels.

@RogerKnight is right that the why matters here. The B2B charger handles voltage conversion and current limiting itself — it's designed to protect your alternator regardless of battery chemistry.

Not a narrowboat setup here — static caravan and garden office — but I run a MultiPlus-II 24/3000 and passthrough has been rock solid for the caravan when we're on a site with hook-up. One thing...

Had a frustrating weekend with my static caravan setup. Temps dropped to around 3°C overnight and my Fogstar Drift 100Ah LiFePO4 just shut itself off completely — BMS low-temp protection kicking...

@Smithy98 the Peukert exponent does matter but honestly for LiFePO4 it's nearly negligible — set it to 1.05 in the BMV and leave it alone.

Just snapped this from the garden office this morning – absolutely glorious frost patterns on the polytunnel.
