Is there a way to use a P2 battery in a P1 phantom using only the P1 electrics? Does any one make an adapter that will work? I know the P2 battery will probably not fit in the P1's battery opening, but I don't have an issue running it outside if the shell. Is it too much of a hassle to deal with? Would a better option be selling the P2 batteries and getting better P1 batteries? Thanks in advance for any help.
