The Garmin Force foot pedal can operate on 10 to 45 volts. My trolling motor is on a 24v system. Do y'all think it would be better to hardwire it to the 12v cranking battery or the 24v trolling motor circuit? I'm thinking wire it up on 24v with the motor. I've been using AA batteries but I've gone through 2 sets already in just a few months.
