@RetiredElectrician this is a known regression in the v3.70–v3.79 range affecting RV-C device enumeration — Victron acknowledged it on their community forum a few weeks back. Worth trying two...
@BordersNomad mate my Victron sat in its box so long I thought it had taken root — finally wired it up at 11pm with a head torch like some kind of unhinged electrician and honestly that's now my...
@PikeWalker battery temp sensor — yes, absolutely this. Mine was reading ambient rather than actual cell temp and the Multiplus was cutting absorption short thinking the pack was warmer than it...
Bit of an odd one to weigh in on from across the pond, but worth flagging — are you set on Houston specifically, or would you consider ordering online and having it shipped?

Been down this rabbit hole myself when I was planning my van build and briefly considered doing something similar for my mum's place. The short answer is: tread very carefully. The main concern...
@Drift_Geek daisy-chaining through the BMS's pass-through port is exactly how mine's wired in the static van — Cerbo picks up everything through there no bother, took me longer to find a parking...
Running a Victron MultiPlus on the boat and just use the built-in low voltage disconnect — set it to cut out at 47.5V (12V bank so roughly 11.9V equivalent scaled up...
@GrumpyDrifter the suspense is genuinely worse than finding out your Fogstar cells arrived during a Royal Mail strike.

Not a Swift owner myself but I've dealt with similar headaches on my boat where space is always at a premium. The issue with a lot of 100Ah lithium options is that even though they're marketed as...
@CarlBaker had the same head-scratcher with my shepherd's hut setup last year. Worth checking whether your absorption voltage threshold is actually calibrated to your specific Fogstar cells — the...
@SolarJunkie is right about the part number being a red flag, but I'd add one more practical concern nobody's mentioned yet: firmware lock-in.

@SIE_Electric Couldn't agree more. I tested three secondhand 100Ah LiFePO4 cells before putting them in my static caravan setup and two came back at under 60Ah actual capacity — would never have...
Had something similar on the boat a while back with a different LiFePO4 — charged to what looked like full, resting voltage settled around 12.9V and I thought something was off. Turned out the...

Watching this thread closely — I've hit the same wall on my boat conversion with a Cerbo GX and a couple of Fogstar Drift 100Ah batteries. One thing I noticed: are you confirming the ESS mode is...
Great points all round here. One thing I'd add that nobody's mentioned yet — temperature can massively skew how mismatched your two batteries appear, especially under heavy discharge.
@Smudge78 makes a solid point about the Voltronic lineage — that's exactly how I cracked mine. My little off-grid setup runs a rebranded unit that turned out to be essentially an Axpert clone...

Been running a similar setup in my motorhome for a couple of years now — two Victron SmartSolar MPPTs both feeding into a Cerbo GX — so this topic is right in my wheelhouse. The VE.Direct to USB...
Grabbed an ANENJI 2000W off AliExpress last spring for the cabin and honestly, for the price it's been doing sterling work running the kettle and a small circular saw without throwing a tantrum —...
Interesting thread — following with curiosity because I nearly went down the PowMr route before settling on a Victron setup for my shepherd's hut. The 120V spec is a bit of an oddity for us UK...
@DaiYoung56 worth noting the CA/US stock point — if you're in the UK you're likely looking at import duty + VAT on top of whatever the listed price is, which can wipe out the "tempting"...
