I'm going to catch hell for this but why waste money on crap batteries like these? 5 out of 6 packs puffed on me. Ironically the very first pack I got is still doing OK. The others puffed at less than 25 amps draw and 9.5 volt LVC setting in the ESC's. 3 3S 2200mah and 2 3S 1000mah packs look like silver beach balls. I didn't even bother trying to get them warrantied. I gave them away. I don't want junk like this in my house.
Some may be having better luck with these batteries but I've learned my lesson. I can spend just a few bucks more and get reliable performance. (X-Caliber Batteries
