Good shout from @GoldenTrekker on the threshold point. One thing nobody's mentioned yet — if the pulses genuinely aren't working and you're in a hurry, a small donor battery temporarily paralleled...
@FenlandOffGrid that's useful context. Quick question though — does this 10x error only show up in the dbus path values (i.e.
RetiredNurse96 | 847 posts | ⭐ Trusted Member @JLB_Boats I had a similar curiosity when I bought my Multiplus II last year!
Been running a modest setup in the cabin for about two years now — 200Ah of Fogstar Drift LiFePO4 cells, a Victron MultiPlus-II, and a Cerbo GX keeping an eye on things.

Been running this exact setup for about 14 months now — Pi 4 with VenusOS large on a decent quality SD card (learned the hard way that cheap cards fail fast with constant writes).
@WD40Wizard78 doing something similar on the narrowboat but running a Pi Zero 2W instead — didn't see the point in paying for a Pi 4 just to shove data into InfluxDB. Couple of questions...
Been down this rabbit hole myself when setting up the boat install. The rack-mount form factor is genuinely useful for avoiding the "battery room" classification some surveyors go...
Been seeing a few threads about this lately and figured I'd chip in with my own situation. Running a Pylontech US3000C stack (3 units) in my garden office setup with a Victron Multiplus II.

Been having exactly this issue with my Multiplus 12/3000 over the last few weeks — bulk phase barely lasts 20 minutes even when the batteries are clearly not full.
@EssexNomad done this on my boat install — two Seplos 3.0 packs, 24V, talking to Cerbo via CAN. The short answer: Cerbo only sees one BMS as the "master" DVCC source.

@CopperSparky — yes, it goes to battery negative, but the critical thing is where on the negative it lands. I learned this the hard way on my narrowboat.

@OffGridJack my static caravan's Fogstar lithium pack has basically been on permanent generator babysitting duty since December — January solar in the UK isn't "gain," it's more of a...

@NigeCampbell81 great timing on this thread — I've just gone through something very similar getting power sorted for a shepherd's hut build, though my use case threw in an extra wrinkle: I needed...

@SunnyNomad @24V_Nerd worth adding though — whilst the usable kWh is technically equivalent, in practice your 48V system will squeeze slightly more out of that capacity because you're losing less...

@TonyLee same issue on my narrowboat last winter. What nobody's told you yet is that your Victron kit will show you exactly where the power's bleeding out if you actually dig into the VRM portal...

Been through exactly this with my van build last spring. Had a Fogstar Drift 200Ah LiFePO4 paired with a BMV-712, and the two were regularly disagreeing by 8-12% — maddening when you're trying to...

So what actually happens in practice if you're running one of these non-UL batteries in a static caravan and something goes wrong with your insurance claim?
Bit of a niche one this, but genuinely curious whether anyone's dug into where Victron actually manufacture their kit these days. I know the Multiplus II range is a Dutch brand and Victron are...
@BatteryPaula that 11pm rabbit hole is real 😄 Living aboard means I never really escaped the grid costs — marina electricity charges are genuinely shocking sometimes, worse than domestic.

@VickyWard the Victron SmartSolar's "absorption" on LiFePO4 is really just a CV hold — and if your BMS is doing its job, current will taper naturally without you lifting a finger, so the...
