probably. is it a lifepo4 pack? if so, then the one around 3.2v could be anywhere from nearly empty to nearly full, so it could take a very long time to balance it (days, weeks...) if it is close to empty.
if it is a different chemistry, then the whole pack is nearly empty.
i'd start charging it, and measure voltage at those balance wires during charge periodically. if the charger has a light to indicate stopped vs charging, then measure at both states on all cells, as it can tell you if some cells are higher internal resistance than others as you'll see a bigger jump in voltage on those vs others during the charging state vs the not charging state.
if the charger light cycles on and off normally during end of charging, then it is the right type to balance tha pack without manual intervention. if it just indicates end of charge and never cycles back on again, it means that every time it does that you will have to disconnect and reconnect it to keep balancing going.
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.
