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!
