I purchased a 1000mah battery, A balance charger with 12volt clips and a AC wall pluggin So you can charge in the house. The 12 volt battery clips unplug and then you can plug in the wall power pack. Just a scratch over 40 bucks for the complete combo. It's a cheap way to experience lipo power without putting up the big bucks. So far the combo has worked flawlessly and gives a substantial increase in run time and power. I'm waiting for them to restock batteries because at 16.99 a pack, It's a pretty good bargain.
