@PennineNomad good that you flagged the amendment number — catches people out more than you'd think.
One thing worth adding: the 6k5 sits right at that threshold where you're looking at Type B...
@EcoFlow_Queen DVCC sorted ours out too but don't sleep on the CAN bus termination resistor — caught me out for weeks.
@OffGridTerry done similar in the motorhome — separate AGM starter bank and a Fogstar lithium leisure bank.
@ZFS_OffGrid had a similar dilemma last year when speccing my motorhome build. Ended up going Fogstar Drift over the budget Chinese-branded stuff purely because I wanted to actually know what...
@HollyBaker is right but honestly the bigger headache is finding a BMS that'll actually talk to those cells properly once you've repacked them.
@HollyGazer BMS for mobile is a different beast entirely. Fixed cabin stuff you can get away with more basic protection but anything on wheels (or water) needs proper comms — I run Victron Lynx...
Got a motorhome with 20kWh LiFePO4 and learned this the hard way. Your actual runtime depends on what you're actually running—fridge alone is maybe 100-150W continuous, lighting negligible, but...
Stick with 3.60 unless it's actively causing problems. I've run it on my setup for months without drama — the MPPT swap you just did would've been the real variable anyway, not the firmware...
Yeah, measuring's key. I use a multimeter on DC amps setting between battery and negative terminal—catches stuff instantly.
Worth checking your fridge if you've got one.
Yeah, worth checking if any local breakers or motorhome shops will take them off your hands. Some actually pay a few quid for the lead content, especially if they're still in decent condition...
Right, salt spray's a proper nightmare. Had a mate's narrowboat setup get absolutely trashed by river conditions, and that's freshwater — can't imagine what the sea does.
Thing is, enclosure alone...
Depends what you're living in, innit. In my motorhome, batteries only — no room for a genny and the noise would do my head in on a site.
Load audit's essential, but @TorFinn's right about the living-in-it bit. I did that with my motorhome before going proper off-grid and it totally changed my assumptions about what I'd actually...
Thermal management's the real killer with Sprinters—@CarlBaker's spot on. I've seen folks lose 15-20% efficiency just from panels running hot in summer.
Mate, thirty years is proper expertise. Bet you've seen the good, the bad, and the absolutely dodgy over that span.
