I have an x9d special edition it a great transmitter but the battery does not last that long. So I want to upgrade it with a LiFe battery because they are more stable than a lipo. I also have a dm9 specktrum module and is operating voltage is 3.5-9v and I know the x9d operating voltage is smaller and higher rage that my dm9 module. I can’t seem to find much retailers that sell LiFe batteries. Does anyone know where I could buy a LiFe battery that volts are betweeen 3.5-9v?
Thanks
