Oh, im interested with more details about your setup. I have 2x APC SmartUPS 1000 units here that I need to replace batts soon. So I slowly think about LFP batts :)
This UPS needs 2x 12V 12Ah batts (RBC4). Can you recommend some LPC batts as repleacement? There is enough room in UPS to but small BMS on top of batts. APC SmartUPC 700 is much worse in that regard. I had one such unit and scrapped it. Batt temps where higher due to cramped space, and so they lifetime..
12V Li-Ion batteries will come with a BMS installed as standard. If you can, buy the ones with a Bluetooth controller included. They are usually drop-ins, so they'll be the same size as the LA ones you are replacing. What you really want the space for is the balancer. Mark.
