Outboard Motor and Trolling Battery setup:

Outboard motors often have only two wires from the motor.  Designed to connect directly to a starting battery, the outboard motor likely will have the alternator and starter connected to these wires internally.  This is an obvious usage of an internal sense alternator.  With their very low ON resistance, the BIC-75150 and BIC-75300 are ideal for use on this type of system when a second battery is desired.  In the case where you want to charge your trolling motor battery while keeping your starting battery charged, consider the following setup using the BIC-75150.

With this setup, first priority goes to your starting battery.  As the alternator voltage rises to above 13.4 volts, the BIC-75150 will switch ON to allow charge current to flow into the deep cycle battery.  The very low ON resistance of the BIC-75150 will allow the full alternator voltage to the deep cycle battery for maximum charge rate capability!
