Trolling motor amp draw and battery sizing data

Minn Kota's charts list a 30 lb trolling motor at a 30 amp max draw on 12 volts, a 55 lb at 50 amps, an 80 lb at 56 amps on 24 volts and a 112 lb at 52 amps on 36 volts. Minn Kota says max draw is intermittent and recommends a deep-cycle battery of at least 110 Ah.
