Replacing SLA in the UPS with LFP
Multiply the performance of any UPS (Uninterruptable Power Source) by replacing the SLA (Sealed Lead Acid) batteries with the LFP (Lithium Phosphate) technology.
The old battery pack on the photos is from APC 1000VA rack UPS model. The nominal capacity of the pack is 24V 14Ah (2S2P configuration). The real energy available from the pack is max 250Wh. This means that a 250W computer may run up to 60 minutes from the UPS with the original SLA battery.
