What our customers say
"The consistency between packs is the difference. I get the same lap times on pack one as I do on pack five — that's never happened with any other brand."

"I've flown nearly every brand on the market. A123 LiHV packs hold voltage through the gate like nothing else, and the cycle life is genuinely better."
