[QUOTE="Still Afloat, post: 498192, member: 32426"] The MK Edge doesn’t have a digital speed control so it uses more current than necessary at any speed slower than 100%. Basically, a resistor is used to dump current which in turn reduces the voltage at the motor. So the slower you go the more power is converted to heat through this resistor. A digital speed control (ESP) basically chops the DC current. When running the motor slower the current pulses are just farther apart. In other words slower speed actually means lower current consumption too. Why am I telling you this? It explains why the MK specs only state the full power consumption. If you upgrade the trolling motor to a “digital” model you may not need a 100 Amp/hr battery. [/QUOTE]
