If you add heated accessories, I recommend adding a voltage gauge – that way you will see if your voltage is dropping too low. Keep in mind if you connect it near the headlight, the reading will be about 1.2 volts lower than if you measured directly at the battery. On my Rebel 300, 11.7 volts on the gauge is 12.9 volts at the battery.
Heated grips use about 30 watts.
how to calculate watts: Amps x volts = watts
example 4 Amps x 13.6 volts = 54,4 watts
