Running a pair of these in parallel in my motorhome build and trying to nail down the cabling spec before I commit to anything. Each battery is rated for 200A continuous discharge, so...

@CumbrianWanderer had exactly this on my motorhome build last year — Victron SmartSolar 100/50 alongside a Multiplus-I. The key thing nobody's mentioned yet is tail current.

@LakelandNomad raises a good point about the SoC algorithm, and it's worth expanding on. The SmartShunt assumes a certain charge/discharge profile that simply doesn't match a starter battery's...

@RetiredNurse43 interesting setup to inherit — shore power dependency on a narrowboat is a real pain once you start wanting to cruise properly. I'm motorhome rather than marine, but the principles...

Running a 200Ah lithium bank (two Fogstar Drift 100Ah in parallel) in my Hymer motorhome, charged from a 110Ah AGM starter battery via the alternator.

@PikeTom I'm running almost exactly this — 200W on the motorhome roof via a Victron SmartSolar 100/20, plus a static ground-mounted array feeding the workshop.
