@FellFrank @RelaySolar — I'll throw another angle in while we're all guessing: internal resistance creep. Been down this exact rabbit hole with my van conversion.

@JackeryGeek yeah the Jackery stuff is basically a closed ecosystem, never plays nicely with anything external.

@JimWilliams71 the 0.3–0.4V is pretty textbook for remote sensing not being configured. In VictronConnect, go into the SmartSolar settings and check whether Battery Voltage Sense is set to use the...

Really relate to this @DailyWanderer! I've got a similar setup on my shepherd's hut — SmartSolar 75/15 feeding a single Fogstar Drift 100Ah — and VRM has absolutely ruined me.

Smudge | Posts: 2,156 @PartnerConvert The Growatt SPF series does have a RS485 port — worth investigating a Modbus-to-USB or Modbus-to-TCP adapter feeding into Node-RED or ioBroker, then pushing...

@Ella1966 just to add something slightly different — have you checked the actual cable runs and connections between your batteries and the MultiPlus?

BlownFuse | 512 posts | 🔌 Static Caravan Tinkerer Something nobody's mentioned yet — parallel AGM batteries make SOC readings even harder because any resistance imbalance between the two means...

Right, so here's how this started. I'd just finished wiring my tiny house battery bank — four 280Ah LiFePO4 cells from Fogstar arranged in a 24V configuration — and the moment I fired up VRM...

@JA_Solar worth looking into a small self-regulating heating pad wrapped around the battery — I run one on a thermostat in my van setup, kicks in around 5°C and draws barely anything overnight.

Finally got my 280Ah EVE LiFePO4 pack wired up properly in the van — 4S, so 12V nominal — and it's been running nicely for a couple of weeks.

@JaneReid68 yeah PWM + AGM is a rough combo for accurate SOC. The controller's basically just guessing at voltage, and AGMs have a notoriously flat discharge curve so voltage tells you almost...

@GlenDixon six weeks in and you haven't posted a full write-up yet — classic LiFePO4 adopter behaviour, too busy actually using the extra usable capacity to come back and tell us about it...

@HeatherOllie is right on the testing front. Did exactly this for my cabin build — grabbed a couple of 200Ah prismatic cells off a Facebook Marketplace seller who was breaking down a motorhome...

@RobBennett93 Worth flagging that the usable capacity difference is the real story here — your 100Ah AGM was realistically giving you ~50Ah before you risked damaging it, whereas the Fogstar Drift...

Classic BMS overcurrent trip — on a boat you've got surge loads that can spike hard and fast. Worth checking what's pulling current at the exact moment it cuts.

Gazza24 | 847 posts Good timing to reconsider the whole setup, @PennineVanLifer. If you're predominantly on shore power, lithium is harder to justify purely on cost grounds — AGMs are quite happy...

KangooSolar | Posts: 1,203 @Mark1978 One thing worth mentioning that nobody's touched on yet - the Multiplus II's PowerControl and PowerAssist features are genuinely brilliant for EV charging...

I've been running a no-name 30A PWM controller I picked up off eBay for about £11 on my T5 van build.

@AngliaOffGrid with a 400Ah bank your 100/30 is basically a garden hose trying to fill a swimming pool in January — a 100/50 or even the 150/70 would stop you weeping into your Bovril by February.
