Only4Fun 169 Posted July 7, 2017 Hi, I am in the UK and I have an old Futaba 4EX 4 channel Transmitter I am running my Tamiya Ford F350 Hi Lift with. The problem I have is it came with an old 1000mah 8 in a row AA NiCad battery pack with a JR/HiTech connector (I think), which now is only lasting 30 minutes or so. I have seen suitable larger mah packs for sale but wondered if I can I use a lipo pack without any modification to the transmitter. Obviously I would have to consider the size of the pack. Any help would be gratefully appreciated. Thanks Share this post Link to post Share on other sites
Backlash 481 Posted July 7, 2017 You could also just replace the old battery pack with an 8 x AA battery holder and 8 x Alkaline or NiMh batteries.. You probably could use a 3S LiPo battery, but you would also need a low voltage alarm as well.. 1 Share this post Link to post Share on other sites
