You can get FMA's LVC device that will work with up to 4-cells of lipo:

Yes, I use the BalancePro fast charger (it's the only one approved for use with the batteries) and I think it works just great. I can't charge my pack at the full 3C that they're capable of since it's a 6400 pack and the charger won't go to 19 Amps :) . It does, however charge the pack to over 80% in about 20-25 minutes, although I can't completely verify that since I haven't run it down to 6v yet either.
The new SkyVolt system from FMA looks great for high-voltage applications, but I don't have a need for high-voltage in racing. You can, however, get a 6s3p 9600 for only about $1,000 ;)
