This is why I picked up 2 of the Peak 3200s in the hard case. This is also why I'm excited about running lipo in my BK2 and soon to be JRXS-R, both run the batteries down the center of the car. This seems to be the safest solution to the lipo hazards. The hard shell is icing on the cake. The hard shell should be considered required in a car where a side impact could directly impact the battery. With some of the dangers involved, a few extra bucks is worth the added safety. It isn't like their going to go bad in 50 cycles. People are claiming 100-200+ cycles on these high quality packs. People have more money in shiny aluminum crap on their car that does nothing, then the cost difference over a couple batteries.
