A standard 6 cell 7.2volt sub c pack like you would use for an R/C car will be needed to run the fuel pump. Your reciever and FADEC will need a seperate stadard 4.8 volt flight pack.
If it's the same as my JDE Wren manual start, the 6 cell car pack is only needed for the starter. The fuel pump runs on a 4 cell 4.8 and the Rx on whatever you use, 4 or 5 cell pack. The advantage of the semi auto start is that you don't have to carry the heavy 6 cell starter pack in the plane.
