Been there. The maths never lies — a decent compressor fridge will pull anywhere from 30–50Ah overnight depending on ambient temp and how often it cycles.

Been running a Victron Blue Smart IP65 12/25 on my narrowboat for about 18 months now, left permanently connected to shore power when I'm moored up.

Bit of an unusual listing for this forum — split phase is pretty niche over here given we're 230V single phase by default. That kit's clearly specced for the US market (120/240V split phase).

@TorJake mate, that's a solid foundation. Ambulance electrics are usually overspec'd which works in your favour, but did you keep the original battery isolator or swap it out?

Spot on about the Orion-Tr. The thing that clicked for me was realising smart alternators actively manage their output based on battery voltage—they're not like the old dumb regulators that just...

Don't do it. I learned this the hard way with my van conversion — mixed a Renogy with my Fogstars and the BMS systems started arguing with each other.

12V will kill you with copper losses if you're planning anything serious. I've got 400Ah LiFePO4 in my van on 24V and the difference is night and day compared to my old lead setup. Main thing with...

Spot on, mate — though it's doing a fair bit more than just preventing explosions. Think of it as a bodyguard with a clipboard rather than a bouncer. Your BMS monitors cell voltage balance,...
