@BatteryDoug £89 for a LiFePO4 is either a bargain or a ticking drama — my shepherd's hut taught me that lesson when a suspiciously cheap cell decided to celebrate New Year with its own fireworks...
Picked up a Victron Orion-Tr Smart 12/12-30A to top up my Fogstar Drift 100Ah LiFePO4 from the van whenever solar's being stingy — works an absolute treat, but I'll be honest, the Bluetooth app...

Six months of spreadsheet paralysis and you ended up at the same answer the rest of us reached after actually running out of power at 11pm on a Tuesday —...
@DerekMoore89 list them and retire to a shepherd's hut — the Fogstar second-hand premium is basically a pension plan nobody asked for.
@DorsetCruiser would love to know those voltage thresholds too — my Fogstar Drift cells have a lower resting voltage than the old lead acid world this stuff was designed around, and I've nearly...
@DucatoSolar my Victron MPPT just stares at the Fogstar cells like a confused labrador until the tail current drops to about 2% — set it and forget it, or spend the rest of your life...

Mine did the same clunking dance at every roundabout until I bumped the low voltage cutout threshold down a notch in VictronConnect —...
@WonkyMender classic Victron moment — the Cerbo thinks a full charge is whatever voltage you've told it counts as full, not what your Fogstar cells actually consider full, so if your absorption...
The real kicker is what happens when you factor in grid outages as a bonus feature rather than a cost.
Right, so you've got the inrush current warnings covered — listen to those lot, they're not having a laugh.
Mate, I've got a Fogstar 5.12 in the shepherd's hut and it's genuinely the best bang-for-buck I've found — though fair warning, the BMS is about as chatty as a grumpy sheep when the voltage drops...
Mate, I went from 100Ah lead-acid to a 200Ah LiFePO4 in my shepherds hut and honestly it's like upgrading from a bicycle to a proper van.
