6 AA batteries equals about 9 volts. So there's nothing in that range for lipo. It'll either be 7.4 or 11.1 volts. That means it'll run like the batteries are dead, or just fry it. I suggest you buy some of these:

funny thing is 6 AA rechargeable batteries comes out to about 7.5V where a lipo is 7.4v, seeing AA rechargeables are 1.25v's each
he would need to mod it to hold 7AA's to get 8.75Vs

AA's in alkaline are 1.5V per cell. Open your tv remote and look.
