I do have to say that the Orion packs did fit nicer in the car but at least I will never lose a TP pack loose on the track
BTW both packs fit nicely with the RCMayor CF straps

Yeah, the 90C and 100C claims you see are bogus. That really is not possible. That has to be burst C rating. The 2S packs i am getting ready to release are 6500Mah at 60C with 120 burst. The packs blew some claimed 90 and 100C packs out of the water.(Not metioning names). I ran a 10 minute main and my voltage just started to creep under 8Volts afterwards.
