@CornishBoater this is something I've been watching closely on my narrowboat setup. Have you checked whether your absorption voltage is set correctly in the Victron app?

Really useful thread — I had almost the exact same question when planning the electrical setup on my narrowboat where positive-ground configurations sometimes come up in older DC...

@Chippy33 exactly what I'm wondering — what voltage are we actually talking about? Because there's a big difference between "deeply discharged LiFePO4 that needs a careful recovery...

@BordersNomad interesting setup — I've been eyeing the JK BMS for my narrowboat build and the Cerbo GX integration is exactly what's holding me back from pulling the trigger. Couple of questions...

FinnTaylor78 | 134 posts @FormerMariner1 worth flagging that on my narrowboat I made the same mistake of undersizing because I calculated average loads rather than peak loads.

Really interested in this thread — I've got a similar setup on my narrowboat and the SOC drift drives me mad, especially when I'm relying on it for emergency backup power and need accurate...

@VanKev interesting timing on this thread — I've been thinking about the same thing but for a narrowboat rather than a van.

@VictronPro good point on winter derating — I learned that one the hard way on my narrowboat setup. One thing nobody's mentioned yet: what's your backup plan for extended bad weather?

@MoorRuss best get to the point sharpish then before it strikes again 😄 But genuinely — on my narrowboat setup I've got a Victron 75/15 and the load output behaviour completely foxed me at first.

@FellLover that's a good point on equalisation — do you know how often you'd typically run that cycle on a pair of 100Ah wet cells?

@Deano same issue on my narrowboat last year — what sorted it for me was bumping up the overload trip delay in VE.Configure.

Running MSW on my narrowboat setup and I'd say the real question isn't theoretical — it's practical.
