Good evening, can I use a replacement Li-po battery in my spektrum DX8 transmitter and continue to use the supplied 12 volt charger for the original 4.8 v nicad battery pack I purchased with the transmitter. I purchased it a number of years ago and am intending (hoping) to get my old quad in the air again. Many thanks, Dave
