Charging & Balacing two packs in series
 

I have a few Maxapms 11.1v 2100 packs that I use in my Trex 450. I want to reduce that charge time by charging two packs at once in series. I have a MRC 989 Superbrain, two Astroflight blinky balancers and a GP Deans series adapter, would it be possible to charge and balance two packs at once would this setup.
