Haha, I have one 50C pack, and one 40C pack. both 2s hard case 5000's from TP. I dont care what they actually put out, all I know is nothing else can keep up on the straight, or the infield with these lipos in touring car. They have got some mad power and dont fade off towards the end of the run. And they last a long time to. Ive had my 40C a while now. Im about to retire it though. Haha, I would be curious to see how they actually compare to there ratings though.
