SAFETY GUIDELINES
General safety
Attention should be paid to all safety instructions in this manual. Maintenance repair work should be carried out by qualifi ed
personnel. A damaged or abnormal functioning Range Extender should not be used. The Range Extender is intended to use
for the charging of JAROCELLS LiFePO4 batteries (24V or 36V range) by an outboard engine which is connected to a Lead Acid
starter battery or LiFePO4 battery.
Safety during installation
You have to connect the Range Extender to batteries under voltage. Make sure you switch o all the users of these batteries
before you make the connections. Prevent shortcut of the wiring during installation and fasten the ring terminals.
Installation and use
Mount the Range Extender close to the starter battery. Make sure the place is free of splashing and dripping water. Keep the
ventilators 5cm free from surfaces to enable optimal ventilation. Connect the 8mm ring terminals with the starter battery.
Connect the grey or red connector (24V is grey, 36V is red) with a contra connector (included in the package). From this
connector wires should be connected to the 24V or 36V battery. For a maximum of 2 meters you can use 2,5mm2 wires. For
wires from 2 to 6m length you have to use 4mm2 or more.
Use the push button to switch the Range Extender in Automatic mode or O . In O mode the Range Extender will not take
current from your starter circuit. In Automatic mode the Range Extender will look at the State of Charge of your starter
battery and whether the alternator is running. If the voltage is high enough the Range Extender will draw current from your
starter circuit and increase the voltage to the right charging voltage for your 24V or 36V battery. As soon as the voltage of
your starter circuit drops, the Range Extender will stop automatically to keep your starter battery full. As soon as you start
the engine again, the Range Extender will start simultaneously.
During normal use the circuit breakers will not switch O . In case a circuit breaker is O : check the wiring on short circuits.
WARRANTY
> The warranty period is two years for the Range Extender.
Warranty provision
> The warranty applies to normal use according to recommendations and within specifi cations of the product.
> Warranty is only given if the purchase invoice can be submitted.
> The warranty does not go beyond repair or replacement of the delivered goods. Consequential damage is expressly stated
excluded.
> In all cases where the warranty conditions are not clear, an attempt will be made to resolve the complaints within reason
unload. This within the provisions of liability.
Liability
> Besides the warranty provisions on the delivered goods, JAROCELLS B.V. will not accept any liability. JAROCELLS B.V. shall
not be liable for any direct, incidental or consequential damages of any nature, or losses or consequential damages or

The most used combination is a Lead Acid starter battery and a 12v service battery, often
combined with a VSR (Voltage Sensitive Relay) so the alternator can charge the service battery
too. In this combination you can also use te Range Extender to charge your 24V or 36V trolling
battery by the alternator. When you stop the outboard engine, the Range Extender will switch
o to prevent that your starter battery will be drawn empty.
Relatively new is the combination of two LiFePO4 batteries. One LiFePO4 battery serves as
a starter and service battery. The other battery is the 24V or 36V trolling battery. By using a
Range Extender the alternator will automatically charge all the batteries without the risk that
the starter battery is drawn empty. When the outboard stops the Range Extender will stop too.
New feature is that all the connections between the service battery and the trolling motor are
disconnected preventing disturbance from the trolling motor to the depth sounder.
