My UPS (APC) has faulty batteries (again). 3 years old, already fried. I don’t mind the poor capacity of the PbAc batteries but this life cycle is horrible (2-3y tops).
Can I replace them with equivalent LiFe batteries like the ones you find on Amazon and such with the same form factor?
Or are there LiFePo4 UPS available in Europe?
Different charge controllers are needed. If the ups manual doesn’t specifically support LiFePO4 the answer is no. You’d likely also need to configure it for that charge cycle if supported.
