I have a 150mah Lipo battery that is running a d/c motor that is drawing 1.4 amps (the motor and battery are directly hooked up)
As the motor runs the amperage draw slowly decreases over time until its below .85 amps (takes about 5 min) then the battery circuitry shuts everything down.
My question is: can I build a circuit that limits the amount of current provided to the motor to 1 amp. Without decreasing the amount of time the motor will run. or hopefully increase run time.
Or should I lower the voltage going to the motor with, I assume, a resister in series with the motor. but will the current draw of the motor and resister equal the draw of the motor alone. or will I get a longer runtime on the motor?
