scanning the boards here looking for 'replace apc ups LiFePO4 Battery'I think you will have better luck if you charge the LFP batteries to about 14.0 and disconnect the charger. Restart charging at maybe 13.2 volts. I don't think the existing charging system in the UPS is doing you any favors. Probably killing the SLA batteries too.
I would probably be inclined to build my own UPS system.
not seeing anyone marketing this yet??Running 2 or 3 ups units and 2 year the SLA replacement's are more money every few years
I don't want to hack up the old apc to much more adding the outboard connector is easy,
the older models can be started without Ac from the grid.
what's the lifePO4 really need to see to keep it happy in this roll inside as UPS service ??
14.6 charging volts? wont the BMS inside a typical 12v pack do the rest ?
My 1500 apc ups is beeping and needs it now.
