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.
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).
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.
