Re: Battery ON / OFF switch mounted on the handlebars

you could but a better setup would be with a relay. that way you dont need heavy gauge wire to the switch. even a switch that handles 20 amps or more is bulky :wink:

i use a car relay at 12volts i step the voltage down from 80volts with a power resister:)
