@SomersetVanLifer shunt goes on the negative terminal of the battery, everything else on the load side of it.
Running a Victron MultiPlus instead sorted this entirely for me — yeah it costs more but the Cerbo integration is actually worth it when everything just talks to each other properly.
That said, if...
@LesPhillips 280Ah at 12V feels like you're limiting yourself tbh. Fine for lighting and a laptop but the moment you chuck a decent inverter on it you'll be sagging voltage under...
@BayTim already covered the voltage so won't rehash that.
What BMS are you running with those Drift cells? That's the bit I'd want to know.
@BlownFuse short answer: don't. Starter batteries are designed for a massive burst of current to crank an engine, then get topped up immediately.

Got a Jackery 2000 Pro sat as buffer but yeah, small genny is the sensible belt-and-braces move.
Depends entirely what you're running in there. 200W/100Ah is fine for laptop + lighting + phone charging.
@DriftGal same boat here, well, same van. Had AGMs in my old motorhome for years and the weight alone should've pushed me to lithium sooner.
@George1975 classic Multiplus bulk charge chaos — seen it on my static and the motorhome both. Nine times out of ten it's the dynamic current limiter not being set right in VEConfigure.
Lol the server hamster's clearly on solar with a dodgy MPPT 😂
Anyway — load output on those Victron controllers is more useful than people give it credit for.
@CornishBoater is right on the M6.
Few things worth trying before you go nuclear on it:
Thread chaser first — might just be mangled not fully gone
If it's properly stripped, a M6 stainless bolt...
Bit of a red flag for me tbh — SolArk and EG4 are designed around 120V split-phase US grid standards.
@SolarKeith don't knock the Fogstar Drift, I've got two of them in my static and they've been solid for 18 months — touch wood.
@Taffy the dual-use thing sounds clever until you're trying to lug...
@Jock had similar grief with my AGM bank before I switched to lithium. The problem isn't just the peak voltage — it's duration.
@TorDweller done this on my static van. Real world numbers matter more than specs — chest freezers cycle on/off so actual overnight consumption is way lower than the rated wattage suggests.
Stick...
