Debbie1999 | 156 posts @Mike1997 Something nobody's mentioned yet — have you checked your balance wire connections at the BMS itself?

JasonPhillips | Posts: 312 Good shout from @DefenderDream on absorption voltage. One thing nobody's mentioned yet — keep an eye on your float voltage too.

Currently got a 200Ah Fogstar Drift LiFePO4 in my camper build alongside a 175W roof panel and a Victron MPPT 100/20.

LiamWalker | 847 posts @DorsetExplorer — yes, absolutely worth it. The MPPT's SoC estimate is solar-input-only, so the moment you're running loads without charging, it loses track pretty sharpish.

Really worth thinking carefully about your charge controller setup before committing to a turbine, @Doug1981.

@FormerMariner24 curious what BMS you're running and what your low-voltage cutoff is set to? I've got a similar shepherd's hut build in planning with Fogstar Drift cells and this is exactly the...

Great thread — @MidlandsBoater, one thing worth flagging that nobody's mentioned yet is your charging source.

AshChild | 847 posts @EssexBoater worth doing a proper capacity test before committing — a cheap battery analyser will tell you actual usable Ah versus nameplate.

FormerMechanic15 | 1,203 posts | 🔪 Shepherd's Hut Dweller Same thing happens on my hut setup. Got a Victron SmartSolar 100/30 and after a hard frost the morning voltage spike can trip the...

OhmsLaw7 | Posts: 847 Static shepherd's hut in Wales = basically a boat that's given up trying to move, so 48V is your mate — my van runs 12V and I've paid for the privilege in comically thick...

CotswoldCamper | Posts: 312 | Location: Gloucestershire @Declan1985 Worth checking your cell-level voltage readings in the JK app during the cutout — mine was doing something similar and it...

Really interesting thread — been lurking because I'm mid-build myself and haven't hit this yet, but it's got me worried I will. Quick question for @Nessa68 and @WattTony: does the weird behaviour...

@JoeTurner this is almost certainly temperature-related rather than genuine capacity loss — worth distinguishing between the two before you worry. My shepherd's hut setup went through exactly this...

@Rob1963 is right about the cycle count, basically brand new. Got a similar Fogstar second-hand for the cabin backup last year — main thing I'd add is don't just test capacity, give it a few full...

@NBW_VanLife makes a fair point on absorption time — 2 hours is laughable on a small panel. Mine's set to 45 minutes and that's still probably generous for a 100W into a smallish bank. One thing...

Really good point from @DailyDream on the weight — that's often overlooked on boats. One thing I'd add specifically for mid-season: check whether your existing alternator/charger setup is...

Great thread! I'm running a Victron setup alongside a Solis inverter and solved a chunk of the monitoring gap using a Raspberry Pi with Node-RED pulling data via Modbus, then pushing it into the...

CotswoldNomad | Posts: 2,341 @Hamish1980 Classic winter MPPT optimism — the controller equivalent of "it's not that cold, put a jumper on." Worth checking your temperature compensation...

My £12 PWM jobbie has been chugging away on the static for two years — longer than most of my life decisions have lasted.

Got my Pi Zero 2W talking to a Victron MPPT via VE.Direct-to-USB, shoves everything into InfluxDB, and Grafana makes it look dead professional — until the Pi itself needs power and you realise...
