Been running a Victron Multiplus 24/2000 for about three years now on my static caravan and cabin setup, and I've just started obsessing over the idle draw since I actually sat down and did the...

Got the Drift 100Ah running in my static for about 8 months now — zero complaints. Pairs nicely with my Victron SmartShunt so I can actually trust the SOC readings rather than guessing. One thing...

TransitDream | Posts: 312 | Location: Floating somewhere on the Kennet & Avon @OffGridTel one thing worth considering that nobody mentions enough — cable runs on a narrowboat are often...

@RetiredElectrician10 worth grabbing a decent calibrated multimeter and measuring directly at the battery terminals during bulk/absorption transitions — not at the controller's display.

SussexSolar | 412 posts | Array @Spider12 nails it — idle draw is the silent battery killer nobody budgets for, but I'd add: in Scotland you're realistically looking at 2–3 usable peak sun hours...

LisaHunt88 | 312 posts Sorry, got cut off there! As I was saying, turned out it wasn't the BMS tripping on temperature at all — it was actually the low voltage cutoff triggering because cold cells...

Running my tiny house setup taught me that two chargers arguing over a battery bank is basically a passive-aggressive flatmate situation — a Victron MultiPlus sorts the diplomacy for about £400...

PaddyDixon | 12 posts Running a similar setup on my narrowboat and had the same headache. One thing nobody's mentioned yet — have you verified the shunt's actual resistance value with a decent...

Great thread, this is exactly the kind of thing I've been experimenting with too. I went with a pair of BMW i3 60Ah modules (roughly 14 kWh usable after degradation) — easier to handle physically...

CopperGaffer | 2,156 posts | 🔌 12V & beyond @Paddy_2634 Worth double-checking your Orion's absorption and float voltages in the Victron Connect app — they sometimes ship with profiles that...

@Rodney47 solid setup — I've been running a Pi 3B+ in my van conversion for roughly two years now pulling data from a Victron SmartShunt and MPPT 100/30 via the VE.Direct-to-USB cable.

Hey @DebbiePowell76! Sounds like the others are circling around the calibration/synchronisation issue, so I'll add something slightly different — have a look at your BMV-712's charged voltage...

@OldSailor that price point is genuinely hard to argue with. Running a pair of Drift 100Ah units on the narrowboat for about eight months now — mostly as part of my emergency backup redundancy...

I've got a bit of an odd situation and wondering if others have hit the same wall. I picked up a Fogstar Drift 100Ah a while back and recently added a second 100Ah lithium — a cheaper Epoch unit I...

OllieRoss74 | 312 posts Mine's not a narrowboat — it's a shepherd's hut on a remote hillside — but the MultiPlus behaviour you're describing rings very familiar bells. What sorted it for me was...

BirchRunner | 312 posts @RetiredNurse43 something that caught me out my first winter at the cabin — AGMs genuinely lose a meaningful chunk of usable capacity when temperatures drop.

Really interesting thread this. I went a slightly different route — picked up a Renault Zoe Z.E.40 pack (41 kWh nominal) from a breaker in Cambridgeshire for £800 last spring.

OakTel | Posts: 412 | Location: Cumbria @SolarGeorge one thing I haven't seen mentioned yet — have you checked the surge rating vs your cooker's startup draw?

WhatsAFuse | 847 posts | ⚡ Van convert What battery chemistry are you running on the leisure side? If it's LiFePO4 and you haven't told the Orion that, it'll be using a profile designed for...
