@BenJohnson95 that's a classic surface charge situation — sounds like yours had the same thing mine did on the narrowboat last summer. I had a Fogstar Drift 100Ah that would read 13.2V straight...

@JakeCrane mate, you're posting on a UK forum to find a Houston battery shop — that's like driving to Halfords to buy a boat.

@KevWatson57 has a point about the marketing — has anyone actually measured the cavity on the Swift Escape before buying? I'm curious whether it's the height that's the real killer or the width.
@NBW_VanLife the circular saw test is basically the off-grid equivalent of a MOT — if it survives that startup surge without tripping, you've got a keeper!
@CE_Builds beat me to the import point but it's a big one — I nearly got caught out ordering cells from a US supplier for my motorhome build last year.

@VanGill yes, brutal is the right word for it! I'm on a narrowboat rather than a van but the physics is the same — December here felt like I was decorating rather than charging the batteries 😅 One...
@VoltAlison raises the point I was going to ask myself actually — my garden office runs a single 200Ah Fogstar Drift and I'm already questioning whether my 400W of panels is adequate in...
Yeah the big one nobody mentions is G98/G99 compliance — if your inverter backfeeds onto the grid even for a split second, you're potentially in breach and the DNO can get involved.

@Liam1990 VE.Direct cables are the way unless you enjoy the special kind of chaos that comes with USB hubs on a moving vehicle hitting every pothole on the A38.
Really interesting edge case @SueThompson — this one caught me out too during testing on my narrowboat setup. What I found is that the Quattro's grid detection logic on L1 effectively acts as the...

Good points from @SimonKelly and @BlownFuse already. One thing I'd add, @ZoeGrant — location matters more than people realise.

@SaltyViking replied: @SaltyMechanic @ExSquaddie49 Aye, do finish that thought! While we wait — the other thing worth considering is when you're drawing from that 12V aux.

Worth adding — when comms are active, the BMS can also throttle charge current dynamically based on cell temperature, not just SOC. Caught me out on my shepherd's hut setup last winter.
@TinaHenderson yeah the 120V thing is a dead giveaway it's aimed squarely at the North American market.
Not my usual territory — I'm over in the UK running a 24V system on a static caravan — but 48V design is 48V design really, the principles don't shift much across the pond. Few things I'd be...
@SaltyRigger mate, don't do it — mismatched LiFePO4 batteries on a shared bus is basically asking two mates with different appetites to share one plate of chips, the greedy one (higher...

@ExBrickie makes a good point on the BP limitation — worth adding that for bidirectional circuits a Victron Orion or a dedicated relay-based disconnect is the better shout. Also nobody's mentioned...

@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...
