I am adding another review, I purchased 2 more of these, and after putting quite a few flights on them, they charge and discharge very even..... have tons of power...Already have the EC3 on...Big bonus....
I have other batteries from eflite and pkz that have puffed and failed that I paid a hell of lot more money for....Though they have a lower C rating , they were the recommended set up...Not good...
Now these gforce 30C have not shown any signs of puffing or failing, they even seem to have more than the listed mAh........going to slowly keep stocking up on these batteries...cant go wrong.
