[E-Revonut]

I'm certain that you won't be happy with the 0606i, it's a good charger and all but not for a dual battery setup such as the e-revo. You said that someday you'll run 6s so I'm going to assume for now your running 4s. The 0606i will charge a 2s pack at up to 6amps so 2 hours to charge 2 seperate 2s 6000mah packs. If you where to go to 6s (2x3s) 5000mah is the biggest pack that will fit. That same charger will only charge a 3s pack at about 3amps so it would take about an hour and 40 minutes per pack! I know this because I started with the eos 0606i ac/dc charger. I now run a eos 0610i duo with an 18 amp Ofna power supply. It will charge 2 3s packs at 1C without a problem! The charger is costly but it should meet your charging needs forever!
