I have been using this new charger from hobbyking that balence charges 4 bats at once. has four processors in one box @ 50w per channel. does all your looking for thats only 150 plus shipping. I have had great luck with it for 2 months now. as long as you have a ps that will do 20 amps plus its a awsome charger. It called the quatro. I just found out that Trinity now sells under Imax Quatro for 179 bucks. If you are interested my LHS has one for 159.95 I could route you to them if needed. I will try to get ya link to hobbyking.http://www.hobbyking.com/hobbycity/s...Multi_Charger_
