Dual Battery Option Hookup
The dual battery option is designed to give you extra battery
power to run accessories, but at the same time give you a safety
feature not commonly found in a dual battery setup. The Supra
Dual battery option features a Voltage Sensitive relay which
always monitors the engine starting battery so that your engine
will always restart.
We recommend that the selector switch always be set to "1". In
the "1" position, the Voltage Sensitive Relay monitors the engine
starting battery, which will ensure that you have a fully charged
battery to start your boat. The "House" or "Accessory" battery
may become drained during a high discharge cycle since it does
not get charged until the Starting battery is fully charged.
In position "1" when the Sensed battery (engine starting battery)
reaches 13.7 volts, the relay closes and parallels both batteries.
When this happens the LED light on Voltage Sensitive Relay
comes on.
In position "2" the sensed battery is the accessory battery. We
do not recommend using this position since it can cause the
starting battery to drain, which would not allow the engine
battery to have enough power to restart your boat.
In position "both", the batteries are paralleled and in a high
discharge cycle, both batteries can become drained, which
would not allow the engine battery to have enough power to
restart your boat.
NOTE: It is recommended that you fully recharge your
batteries using a battery charger periodically or after a
session of high discharge (lots of accessories running for
an extended period).

Battery Box
The battery is mounted inside the observer's seat storage
compartment. Location may vary slightly depending on the
model.
NOTICE: It is recommended that the battery cables be
disconnected from the battery when the boat is placed in
storage.
Avoid damage or injury from battery acid. Ensure that the
battery is properly secured before using boat.

NOTE: It is possible with this system for accessories to shut
down when the engine is running due to the accessory
battery draining down. This is a safety feature. This system
monitors the starting battery and will sacrifice the accessory
battery so that you are not stranded on the water with a
weak starting battery.
NOTE: We highly recommend using high quality "Dual-
Purpose Batteries" in both the starting and house
position.
