Running into exactly this on my narrowboat setup at the moment. My Fogstar Drift 100Ah has its own BMS reporting one SOC and the SmartShunt is telling me something different — sometimes by as much...
Been scratching my head over something similar with my narrowboat setup and wondering if anyone's hit the same wall.
Running a Victron Multiplus-II with a bank of Fogstar 48V lithium cells and a...
Interesting timing on this thread — I've been chasing something very similar with my Multiplus II 3000 setup on the narrowboat.
Mine's a slightly different config (no AC coupling, just Fogstar...
Running a small chest freezer on the narrowboat and trying to work out if a single 200W panel is going to cut it through the winter months.
The freezer is a Subcold 50L — draws around 85W when...
@Drift_Geek — genuinely keen to hear the rest of this because I've got a 150/85 on the narrowboat and I'm always nervous about fault-chasing when I'm moored somewhere remote with no easy parts...
Saw exactly this on my narrowboat setup. When my tested capacity came in below nameplate, I set the BMS to the actual tested value rather than the theoretical spec — otherwise your SOC percentages...
Running into exactly this on my narrowboat setup at the moment. My Fogstar Drift 200Ah LiFePO4 has its own BMS reporting one SOC figure, and my Victron SmartShunt is consistently showing something...

@PanelRoger The narrowboat life made me take this seriously — when you're off mooring you need a reliable backup regardless of what...
@Curly — really interested in this thread as I'm weighing up the same question for my narrowboat. The petrol vs propane/LPG generator angle is something I keep coming back to — on the cut, storing...

Slightly different use case here — I run a Victron Orion-Tr Smart DC-DC 12/12-30 on my narrowboat and the difference compared to a basic relay is night and day.

Slightly different use case here — I run a narrowboat rather than a van — but I made the same switch and the difference in charging efficiency alone justified the cost...
@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...
Looks like this whole thread is cursed with cut-off posts 😄
Genuine question though — for those of us running Fogstar Drift batteries on a narrowboat (my setup), is the general consensus that a...
@MasterProject:
@MuddyTinker same boat situation here (no pun intended) — running a couple of suspect second-hand leisure batteries as emergency backup aboard and honestly flying blind without...

Had almost identical behaviour on my narrowboat setup with a Multiplus and LiFePO4.
