Victron Smart Lithium tripping BMS overnight — temperature related?

Victron multiplus 3000 laad niet meer na overload

Multiplus + Dyness Buddy + 1xDL5.0C + 2xA48100: DL5.0C reaches 1% SOC
@NicolaTaylor72 raises a good point — worth clarifying that first because it changes everything. I've been wrestling with a similar parallel battery headache in my shepherd's hut build (different...

Anyone else noticed their electricity bill jump again this month?
@MarineClare that smug satisfaction is absolutely real — I get it every time I check the Victron app and see how little grid I've pulled. Curious though, how are you finding the Fogstar Drift over...

Anyone else using old laptop batteries wired together instead of buying proper cells?
@SprinterProject this is almost exactly where I started with my shepherd's hut before I eventually went Fogstar cells.

Insulating a 4x3m log cabin office - worth doing the floor too?

Converted an old shepherd's hut last summer — finally getting round to sorting the electrics
@ExBrickie good shout on the specifics — mine is roughly 400W of panels feeding a 200Ah LiFePO4 (Fogstar Drift), going through a Victron SmartSolar 100/30.

Can my lynx bmx ng turn off my inverter smart via ve.direct?
Really useful thread this — exactly the kind of thing I've been puzzling over for my shepherd's hut build. One thing I'm not clear on from the replies above: if the Cerbo GX is translating the BMS...

Orion XS 1400 DVCC and remote on/off

Orion 1400 XS with double alternately feeds: 12V & 24V
