Shunt mod switch using relay?
I have been considering operating on my controller and installing a shunt so my ebike would climb and accelerate better. I do not want the shunt mod to be on all the time since travel distance is a factor for me. I was thinking of using a 30 amp relay that would switch using 12 volts to turn the shunt on and off. my ebikes motor is 48volts and 500watts. Any reason this wouldn't work?
