INTRODUCTION
Congratulations on the purchase of the Rebelcell 12V80 PRO lithium battery. The 12V80 PRO is
a powerful battery specially developed as an
“all in one” battery: both for starting an outboard
engine and / or as power supply for (multiple) depth sounders and / or trolling motor. It is a
‘drop in’ replacement for a start / service lead battery and can be charged via the outboard
engine.
The 12V80 PRO is well suited for deployment in cold weather: the
Frost Control function allows
you to charge even in sub-zero temperatures. And with the convenient
Rebelcell app, you can
monitor charging status, temperature and battery health, among other things, for a worry-free
day on the water.
SAFETY PRECAUTIONS AND WARNINGS
Your Rebelcell 12V80 PRO battery (hereafter battery) has been engineered with a safe and long
user life in mind. Please thoroughly review this manual and follow the safety precautions. Not
doing so may invalidate the warranty and result in the malfunctioning of your battery.
• Use cables of sufficient thickness to connect your equipment to the battery for safe use.
Never use crocodile clamps to connect your equipment to the battery! These connections are
not safe and can result in heat development with damage to your equipment or battery.
• If you use your battery to power equipment (e.g. depth sounders or trolling motor) use a
suitable fuse between the battery and your equipment to protect both.
• Avoid direct contact of your hands with both battery terminals: danger of electric shock!
• Avoid reversing the + and – battery terminals when connecting the battery. This can lead to
irreversible damage to your battery!
• Only use isolated tools when installing your battery. And keep metal objects, such as jewelry,
away from the battery.
• Your battery is ‘waterproof’ according to the IP65 standard. To avoid issues, we recommend
placing the battery in a waterproof battery container and/or on a elevation to ensure that the
battery is never partly or fully in the water on the bottom of your boat.
• Fix your battery (e.g. with fixation bands) on a vibration free surface to ensure that sliding is
impossible.
• When used outside the permitted standards (e.g. high load) your battery will automatically
turn off. No power will be available until the battery can operate within these standards.
• Avoid damaging the battery by dropping it. In case of external damage do not use your
battery but have Rebelcell check for proper and safe operation.
• Place the battery in the coolest environment possible. Do not expose the battery to sources
of direct heat such as (open) fire, heating or exposure to direct sunlight for extended periods
of time. Long-term use in high temperatures (> 40 ° C) has a negative influence on service life.
At a temperature of 55 ° C, the battery will shut itself down until a normal operating
temperature is reached.
• The battery is classified as dangerous goods for transportation purposes (ADR Class 9).
Review the Material Safety Data Sheet (MSDS) on our website for more information.
• Your battery may only be opened by Rebelcell for repairs. If you open the battery the
warranty will be void.
INSTALLATION
• Your battery is equipped with screw battery terminals in size M8. Remove the protective caps
on the battery terminals before use and fully charge the battery with a suitable battery
charger (the battery is not fully charged yet due to transport and storage requirements).
• Connect your outboard / depth sounder / trolling engine cables (with M8 tongue connectors)
to the battery terminals and securely tighten the bolts with a socket wrench: improperly fixed
terminals can be dangerous and generate heat, which can lead to irreversible damage to
your equipment or battery! If you use your battery to power equipment (e.g. depth sounders
or trolling motor) use a suitable fuse between the battery and your equipment to protect
both.
GUIDELINES FOR USE
Your battery has been specially developed as an “all in one” battery: both for starting an out-
board engine and / or as power supply for (multiple) depth sounders and / or trolling motor.
The 12V80 PRO is a ‘drop in’ replacement for a start / service lead battery and can be charged
via the outboard engine.
Starter battery for your outboard
The 12V80 PRO can deliver a starter pulse current of 450A (5s at -12 °C) to 900A (5s at 15 °C).
Thanks to the high starter current (also at cold temperatures), frost control function (allow-
ing charging up to -20 °C) and low self-discharge (< 3% per month) the 12V80 PRO is the ideal
starter battery for petrol outboards up to 350 HP in all weather conditions. This versatile pow-
erhouse is well suited for deployment in cold weather: the
Frost Control feature allows you to
charge even in sub-zero temperatures.
Power source for (multiple) depth sounders
The 12V80 PRO can be used with all brands and types of depth sounders without restrictions
(no DC stabilizer needed for sounders). Thanks to the high capacity and onboard charging via
your outboard it is very suitable to power multiple large screen sounders simultaneously.
Electric trolling engine
The battery can handle a continuous load of 100A making it suitable for use with all 12V trolling
engines. As the battery voltage remains nearly constant until the battery is almost empty, you
will notice that thrust remains high and constant. If you to use your trolling engine in a lower
gear this can significantly increase your runtime.
Discharging
Fully discharging your battery is not harmful. The battery is protected by an advanced integrat-
ed Battery Management System). Charge the battery as soon as possible after a full discharge.
If the battery is not used for a longer period of time disconnect all wires from the battery to
prevent unintended discharge. Due to low self-discharge (~ 3% per month) voltage may drop
below critical levels and damage the battery irreversibly.
CHARGING
Via your outboard
After you start your outboard the battery is recharged via the outboard alternator. The voltage
