Only one run on them, but I was rather impressed I must admit. When I tapped the throttle from a standstill after putting them in, the damn truck flipped on its lid instantly- so much punch, and it lasted all through the run too, even when the speed started dropping off. Temps were very good, especially concidering how hot the Nimhs got with the same setup. When I charged them last night, all the cells were within about 0.05v of eachother too- ideal lipos for a cheap and not too powerful setup. I need to put alot more cycles on them to see how they hold up, but they didnt puff on the first run, so its all good so far.
