@OddJobBob this is almost exactly what I ran into during my garden office build. Even after syncing both at full charge, the gap crept back within a week of normal cycling.
One thing nobody's...
@ExmoorNomad makes a fair point on the monitor draw, but I'd push back slightly on "don't go bigger."
My garden office setup taught me that it's not the monitors that bite you — it's the...

@Compo89 Curious — are you using any external cell monitoring on top of the BMS?

Interesting thread — I've got a Fogstar Drift in my motorhome too and noticed similar quirks last winter.

Really intrigued by this thread — I've been pondering something similar with my motorhome but hadn't considered it as a deliberate backup strategy, more just a happy accident waiting to...
@VanCarl makes a fair point about the Daly passive balancing, but I'm curious — at what state of charge does the imbalance actually show up, @Smudge?
Running a 200Ah Fogstar Drift LiFePO4 in my garden office setup, with a Victron SmartSolar 100/30 MPPT.

Had almost exactly this on my garden office setup last year. Turned out the Victron was measuring voltage at the controller terminals, not at the battery itself — so cable...

Had a frustrating weekend with my garden office setup. Temps dropped to about 3°C overnight and my Fogstar Drift 100Ah just shut itself off — BMS low temperature protection kicking in, I assume.

Really useful thread — exactly what I've been trying to figure out for my setup.
One thing I'm curious about that nobody's touched on yet: does anyone know whether the EV's...

@CurrentAffairs that's a fair point about precision — but even with loose definitions, my concern is practical.
Has anyone actually got one of these running in a motorhome setup? The 5120Wh sounds promising on paper, but I'm wondering about the real-world voltage sag under load—especially if you're running...
Fair points from you lot, but I'm curious about the middle ground here. @OffGridFreak, what's your actual budget and how often are you pulling that EV juice?
The reason I ask is I've got a Fogstar...
Quick question for you lot—how many of you are actually comfortable with just VRM for the critical stuff, or does everyone end up adding secondary monitoring?
I'm looking at setting this up for my...
That's rough, but honestly unsurprised. I'm in the early planning stages for a motorhome conversion myself and already dreading the DVLA side of things.
Quick question though — did you find that...
