regulator in your alternator will charge the battery with the suitable charge current and voltage
(normal output voltage ~14.4V). The charge current is automatically reduced as the battery is
nearly charged and will stop charging when battery is full. If the regulator does not function
properly your battery can be damaged. Any damages due to a malfunction of the voltage
regulator will void the warranty.
Via the battery charger
If you do not use your outboard regularly the alternator will not fully charge your battery. In
that case use the Rebelcell 14.6V20A battery charger or other suitable charger for 12V LiFePO4
batteries to top up your battery. Read the warnings on the battery charger before use and
follow the instructions. Make sure the charger power cord is disconnected from the AC outlet
and the power switch (if applicable) is off. Connect the charger to the (+) and (-) terminals of the
battery and ensure you tighten them with a socket wrench. The power cord in the AC-outlet
and turn the power switch (if applicable) to ‘on’ to start charging. The charger LEDs indicate the
charging status andthe battery bolts will automatically stop when the battery is fully charged.
Unplug the power cord before disconnecting the charging cables from the battery. If you use a
unsuitable charger the warranty is void if damage occurs to your battery.
Frost-control: safe charging during subzero temperatures
Irreversible damage can occur if you try to charge your battery when cell temperature is below
0 °C! The frost control function is activated automatically by the BMS if cell temperature is
below 0 °C and a charge current (from alternator or charger) is available. The BMS uses the
charge current to preheat the cells and increase temperature and will automatically start
charging the cells if temperatures are sufficient. This makes the 12V80 PRO ideally suited for
use in cold weather markets.
Storage
When the battery is not in use for extended periods of time charge it to 50% and disconnect
all cables from equipment and store the battery in a dry location (above 0 °C). Due to low
self-discharge (~ 3% per month) voltage may drop below critical levels and damage the battery
irreversibly. Check charge status at least 1x per 3 months and charge when needed.
Rebelcell Bluetooth App
The Rebelcell Bluetooth (BT) app is available for both Android and iOS (Apple). The app provides
the ability to view battery capacity, battery status, charge and discharge currents and the num-
ber of charge cycles, among other things. Please review the Rebelcell BT app section later in this
manual.
BMS and safety
The BMS protects your battery and contributes to a long service life. Functions of the BMS are
protection against deep discharge, overcharge, high temperature, frost control, short circuit,
high currents and cell balancing. When certain safety thresholds are exceeded, the battery will
shut down as a precaution and turn itself back on when the battery operates within specifica-
tion. If this does not happen automatically you need to disconnect your equipment (and in
some cases connect to your charger) to reset the battery. After a few minutes you can recon-
nect your equipment. The activation of the BMS may seem like a failure, but it is not. If it occurs
repeatedly this can indicate a malfunction of a component in your electrical system or overheat-
ing of the battery. If this happens contact your electrician to check your electrical system.
Warranty
Your battery has a standard 3-year warranty from date of purchase. Refer to our general terms
and conditions for detailed warranty conditions. Please retain and store your purchase receipt,
as it is required for warranty claims.
