Have this in an SC10 4X4 with a castle 5700KV. Provides more than enough power. As anyone knows the SC10 4x4 wasnt designed with 3s in mind.This battery fits nice and snug in the tray. You will have to remove the drive belt cover,front slipper housing and pulley to get it to fit in. A 3S with this setup is definitely overkill but its just fun.
