The answer is all your battery problems is LIPOS. Derek, I'm telling you dude, lipos are SO much nicer. Hobbycity.com has EVERYTHING you need. 5000mah 2s 7.4v lipos for $27. That'll give you over 30minutes of run time. Plus they have chargers and lipo sacks too. 100% safe and 1000times better than those Nihm's. Once I buy the VXL Rustler off my father-in-law, the FIRST thing I'm doing is ordering at least 4 of those 5000mah lipos. 4 batteries and over 2 hours of run time. WOW!!! Step it up, come play with the big boys.......hahahahaha j/k
