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?


It was on YouTube like 6 years ago. I did it 4 years ago and they’ve been running great.
You need to get a lifepo4 that has a lead acid drop in BMS.
