Futaba 4EX 4 channel Transmitter Help Please.

[Only4Fun]

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

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..
