Hello! First I'd like to apologize if this is in the wrong spot, and while I know it's not the primary focus of the forum this seems to be the only place I've found good discussion on battery tech. I'm looking to replace the batteries in my APC SUA3000R2X145 which uses 4S2P 5.5AH SLA batteries...

Thanks for the reply! I think even if I can't change the parameters, it should be pretty close based on 13S li-ion vs 4S 12V SLA voltages. So I bought 6 of them :) Now I have to figure out what to do with the extra 4, since I only need 2... Possibly stupid question, but do I strictly need 1...
