Right. I don't know how to set the voltage limits2.99 is to low id not go lower than 3.2v as the voltage falls off a cliff going any lower.
when you put 5 cells as 1 pack it is as only as good as the weakest cell voltage wise so some cells might have a bit more left in them but only on there own.
so when 1 cell in the pack reaches cut of voltage it will stop discharging the hole pack.
like it only takes 1 cell in a pack of 40 to go bad and the bms stops charging the pack
