Thats what i had thought at first but it does it with all 5 of my batteries and all of my batteries work just fine with in my friends gtb system.

There shouldnt be an issue using the gtb 2.4ghz version with my dx3s radio is there? my radio works fine on every other car i own just wondering maybe it does not work so well with the gtb since its a newer 2.4? just throwing things out there.
