KDS innova 550 3D RC Helicopter Testing the battery with a bad cell

Enjoy the new 3D aerobatics flight video of my KDS innova 550 3D RC Helicopter. One of my very good 6 cell battery that I bought for this helicopter, has developed a bad cell. So today I brought it for test flight and see if battery cells can get back to balance.
