Running a small chest freezer in my van conversion and trying to work out if my 200Ah Fogstar Drift is going to cut it overnight without solar input.
The freezer is a Alpicool C15 (15L) — pulls...
Been pondering this one for my van build actually — got two Fogstar Drift 100Ah LiFePO4s running in parallel via busbars and wasn't 100% sure where to drop the Smartshunt in.
From what I've worked...
@ExSquaddie49 good shout on VE.Configure — worth adding that you can also set the temperature threshold for when the fan kicks in. Mine was running the fan way earlier than it needed to.
@StormyViking makes a fair point tbh — our DNO rules, G98/G99 regs and export tariff stuff (SEG etc.) won't mean much to you across the pond.
That said, the core battery/BMS tech is pretty...
Bit late to this thread but yeah, had this exact nightmare with my van build a couple of years back so I reckon the same principles apply to garden offices too.
The culprit for me was relying on...

@AlanPalmer57 done something similar in my van build. Ended up using a Victron SmartSolar with a DC-DC charger (Victron Orion-Tr Smart) between the two banks rather than trying to split direct...
Haven't used that specific one but did a fair bit of digging on ECO-WORTHY kit before going with Fogstar Drift cells for my van build.
Main thing I'd check — who actually makes the cells inside?
@Chris1966 yeah been doing similar in the van for about a year now. Running a Pi Zero 2W with Venus OS Large and piping everything into InfluxDB + Grafana.
@StormyMechanic yeah floor insulation is massively underrated tbh. In my van build I put 50mm PIR under the ply floor and the difference in thermal comfort was night and day compared to vans I've...
Had this exact thing with my van build. Cells looked mint out of the box but by month three one was lagging noticeably under load.
Turned out my Daly wasn't balancing aggressively enough —...
Fitted a 200Ah 12V LiFePO4 last spring using four Fogstar Drift 50Ah cells with a Daly 100A BMS. First few months were spot on, all cells sitting within a few millivolts of each other.
Haha seems like this thread is cursed — everyone's getting cut off mid-post 😄
Anyway, van rather than boat here so slightly different context, but I went Fogstar 100Ah cells with a Victron BMS and...

Yeah had this exact issue in my van last January. Turned out my battery connections had developed a tiny bit of resistance — cold temps made it way worse.
