My poor old UPS is on it's last leg. Its been running my server and some network gear for many years now, but at the last power outage it ran for 40 mins and then just died when still reporting a 40min battery time left. Sure i could probably calibrate the batteries, but no one wants to mess with 5-6 years old lead acid packs.
The UPS is running with minimal load for its size, it reports the load @ 7%, or just shy of 200W.
My question is if there's a more or less simple way to convert such an UPS to Lithium? It's running a 6S Pb pack today so about 96V nominal. I guess that not even LiFePo4 will be fine with the build in charge parameters, and would require 30 cells for the right voltage.
Anyone know of any conversions or use cases for the UPS? Or is it just a waste of time? Should i just spend the money on a proper all in one charger/inverter/MPPT and add some solar panels for prolonged runtime and reduced power bill?
