My buddy has spent the last year testing LiPo batteries. CNHL have performed very well, even beating out a lot of supposedly better, and far more expensive batteries, including SMC. Liperior have been testing reslly well also. Some of the higher end Turnigy batteries are very good.
As for...
That X-Maxx slider... you can buy all that stuff brand new off Jenny's for just a tad more than that.
And gensacearespammers batteries are not that good. A friend has tested them. For the money, you can get much better batteries. Look at CNHL, Liperior, SMC for batteries.
