SpyderBatteries 6S 4000mAh 30C

Product Review (submitted on February 11, 2012):
These batteries are lighter than most 6s4000 packs out there but perform much better than those in the same weight class and give longer flights as well. I've had mine for about a year and a half now and they are still performing very well. IR has increased from ~1.5mOhm per cell to about 2.5mOhm per cell.

I wish they had had the 12s4000 stick packs when I got my batteries.

Please wait...
