Note that the condition that you described (pack got hot and puffed during charge) is nearly always due to overcharging that results from an issue with the charger or charge settings rather than any problem with the battery being charged. What charger are you using and have you verified with a DMM of known accuracy that your charger is not charging beyond 4.2 volts per cell?
Thanks for the feedback. I am using a Bantam BC6 and I was charge/balancing a 4S 2500ma 30C pack at 2.0 amps. The measured voltage during charge is 16.8v. I have used this charger for over year with no problems and this pack was the very first that I had a problem with.
Appreciate your comments
