I have a 25amp Sabertooth Motor controller that can be powered by my 12v car battery. I have big 24v wheelchair motors attached to the motor controller.
I do not know how much current that the motors consume. However, I installed 20amp fuses to make sure that my motor driver does not get damaged in case of current overflow or a motor stall.
Having that said, the fuse blew out several times when I test-ran my robot. Everything works fine, except the motors consume very high current from the battery.
Can I possibly connect a resistor in series with the motor driver to make the circuit "safer" to avoid blown fuses? Will a voltage regulator help? OR does anyone have any other suggestions? (please be specific)
