Ping batteries are awesome the way they balance with their
BMS. They actually have the abilityy to charge the cell up to the maximum recommneded value and switch the charger off if any cells reaches this max voltage.
If this happens the bms disconnects the charger and allows the bms to burn the volts the cells down, I don't think the gm charger does this and this may explain the common failures with the gm packs we see.
Watching the signalabs bms cell leds and charger switch off and on you can see how successfull this on and off process works to bring the lower cells up to speed.
A battery can take ages to balance. I know my new pack took 12 hours for all cells to be balanced when new.
When the charger is engaged it delivers 2 amps and when sitting it only gives 400ma depending on the size of the pack. This is not even close enouugh to balance a pack in a single charge.
Different temperatures through of a pack is quite common. Like if I leave my garage door closed in the morning the sun heats one side of the bike up hot.
To charge an pack with one side warm and the other cool is a very big NO NO!.
I just spent $1700 on two packs I like to ride them hard then spoon them. But my packs are awesome and deliver above there rated capacity and still havent seen LVC.
That just me.
