SAFETY GUIDELINES

General safety

Attention should be paid to all safety instructions in this manual. Maintenance 
repair work should be carried out by qualified 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.

Safety during installation

You have to connect the range extender to batteries under voltage. Make 
sure you switch off 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 Lead Acid 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 van use 2,5mm

2

 wires. For wires from 2 to 6m length you have 

to use 4mm

2

 or more.

Use the push button to switch the Range Extender in Automatic mode or Off. 
In Off 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 with not switch off. In case a circuit 
breaker is off: check the wiring on short circuits.
