Quality batteries for racing.
I have done stock class 17.5 offroad racing for a few years off and on over the last decade. I am now doing 17.5 carpet racing as well as onroad parking lot 21.5 and 25.5 racing. 2S hard case batteries. I am ANAL about storing my batteries at 3.85v they are never more than a few hours at charge. in all this time I have NEVER had a single battery that didnt puff in less than a year. I have tried several brands. SMC, Hobby king, and some $$$packs in the past I forget the name to. in that same time I have had 30 soft pack air batteries and I maybe lose a couple to puffing. my latest batch of HK batteries are all puffed after maybe 4 months.
does anyone make a hard case pack that isnt total dog S$%^
