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
off to prevent that your starter battery will be drawn empty.
Relatively new is the combination of two LiFePO
4
batteries. One LiFePO
4
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.
