I'm ordering a DN G2 i guess. Primarily because it's relatively cheap and has the ability to charge two batteries at the same time.

But maybe there are better 'dual' chargers?
(I'm also getting a bigger battery, i've flown almost 25 minutes (with a cooling period in between) on a 1100mAh 26C battery!)
