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. (Posted on 9/15/2014)
Bought 2 of these and have 4 or 5 cycles on them ,seem good so far...good solid discharge, powers my planes well, stays strong all the way to end of flight...Good value. (Posted on 8/5/2014)
I have run these for a while and as long as you don't take them to low and you balance charge them I get good life from these G-Force batteries. As far as length of flight for the money good length and hold up pretty good IF you take care of them. (Posted on 8/26/2013)
I have a Parkzone Extra 300. The recomended battery is the PKZ1029, but of the 6 that I have. All of them have puffed up while flying the Extra, even when not usinf full throtle and flying for only 6 min. These Gforce 30C 2200MAh fit in the Extra, haven't changed shap at all after a month of flying daily. AND, you can get 3 for the price of one PKZ1029. Buy these! They work great in the Parkzone F4U too. (Posted on 9/1/2012)
