Hey, Chris.I like 4s for bashing, http://www.spcracing.com/index.php?productID=61 I really like the run time from 8000 mah lipos,and the speed of about 45 seems pretty good.I would start looking at something like this for a charger http://www.hobbycity.com/hobbycity/s...r_&_discharger They also sell the zippy lipos. BTW these are if your on a budget,they are not the best available.
