The 9918 should handle it easily. 1 question, is it one of the older ones? The old 9918's had a problem with brake fade. Anyways, the weight difference will be negligable, the emoli cells should be fine in a buggy.

paintballer1331, the runtime is mainly based on how much MAH the lipos have, what motor your running, and what terrain. It is almost impossible to give exact numbers to you. BTW welcome to the forums!
