Thanks for the replies.
bobf24, I also wanted a transmitter lipo also and was curious if they were able to be transferred. I didn't want to start a new topic for the one question. I just noticed that my JR Z-1 and the Spektrum both use 8 AA cells and figured that maybe I could switch from one to the other if I get my JR repaired.
Since people have said my ICE will work, how do I balance the packs. Do I need to buy something. This is all new but I can see the benefits once I get up to speed (no pun intended).
