Lipo in my DX3R?

U don't have to use that rinky-dink wall charger, i've been using the same charger i use for everything else and charge through the built in plug for 5 years now with no problem. I just cut the end off of the wall charger that came with the radio and got a deans pigtail, and put the negative radio plug on the positive side of the deans and positive on negative, works great.
