Perhaps you could give a bit more info as a 3A gel cell should most certainly power this loco.

Do you use radio control ... if so what is the radio and how is it wired into the circuit?

Second, how do you recharge the gel cell, what are you using for a charger?

Regards ... Doug

Del makes some good points ...

I am not familiar with your radio but ... must have a minimum voltage for activating them properly. Does yours function at 12V ... both to receive the signal and to control the voltage to the motor?
