I just picked up a SMC 1400 today for my V and it's very quick. I plan on getting a lipo after I put the mamba 25 comp X in it. I got the SMC pack for $25.00 which is the same price as the pro boat combo at my lhs. I've had good luck with smc cells in my cars so I figured it would be a lot better than the 1100 mah prbo packs. And I allready have 3 ni/mh chargers and 1 lipo charger. My charger charges the 1400 pack in like 20 min, compared to 2 hrs or whatever the prbo one does it in.
