This is a 60v 40ah pack i got that appears to be 2 20ah packs in parallel (based on the 2 pairs of wires coming out). After a short while, the range dropped and charging time was cut in half. I suspect that one of the 20ah packs wrapped inside has become disengaged somehow, I checked in the bms and everything looked to be properly connected and there were no obvious problems, is there a way to check each 20ah side without tearing the whole thing apart? and does my assumption even make sense? any help would be appreciated.
