Outboard
Motor with Backup Battery:
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. The BIC series are
ideal for dual battery usage with this type of system. With the
very low ON resistance of the BIC-75300, you can use a backup battery
(kept fully charged automatically through the BIC and isolated from
main battery loads) and ready to use in starting and operating your
boat when the main battery lacks sufficient power.
With this setup, the Backup Battery will maintain
maximum alternator charge voltage due to the BIC-75300 very low ON
resistance. If the alternator quits or the main battery otherwise
is drained, the backup battery will stay charged and ready to
use. In a situation like this, simply flip the Remote Switch to
ON and the backup battery will supply
starting and operating power to your gasoline outboard motor.
