Yes but i was my fault.
Never keep batteries connected for longer time when the charger is not connected to power.
Yesterday I charged cell 1 alone and discharged then the whole pack with about 7A and got 1900mAh out from this 2100mAh pack.
Looks good but later I will try it in my Acromaster with draws up to 40A and I will see if this pack still has performance or not.
