    Yeah they are both 14s chargers when the battery gets to almost full charge the chargers cuts in and out like it should be balancing the pack. I figured I had best ride my bike to work today to drain the battery, I am just recharging now so will report back soon. Thanks Again.

    Hi slowco, I removed the last cell group and charged them as you suggested. All the cells seemed to check out ok so may have been a loose connection to the caps? Charged all cells in that group to 4.05v and built them back up, I then left the whole battery on charge over night and all day today...

    I do have a bms attached to the pack and have 2 chargers one 2amp and a 4amp but the pack gets to about 57.7v even with charger on overnight. The charger does cut in and out after a few hours like the bms is working!
