Australian designed,

engineered and

assembled batteries

Other features of the DC-DC charger include three (3)

switches:

Current Selection Switch

This switch allows you to select the amp charge rate from 10A

to 20A.

Most vehicle cigarette sockets on the dashboard are rated for

10A only. So, if you are using the 10A vehicle cigarette socket

to charge the lithium battery then select the 10A on the rocker

switch.

If your vehicle is fitted with a 20A connection, or you are

connecting directly to the start battery, then you can select the

20A charge setting on the battery.

Beware: If you select 20A when connected via a standard

cigarette socket, you may blow the fuse connected to that

circuit in your vehicle.

Direction Switch

This switch provides the ability to reverse the DC charge

direction (Out) so that the lithium battery can be used to

charge a flat vehicle start battery. The normal charge direction

(In) uses the vehicle alternator to charge the lithium battery via

the start battery.

Note – this feature is not intended to ‘jump start’ the starter

battery. It is a controlled charge (at the selected current based

on the switch, 10A or 20A). So, you might need to wait for

30-60 minutes before the start battery is sufficiently charged

to crank the vehicle engine, depending on how flat the start

battery is.

External Shunt Switch

An external shunt can be applied across the two (2) black

negative terminals to measure current in and out of the battery

for accurate state of charge measurement, including charge

current from the built-in DC-DC charger.

If an external shunt is applied, select Yes.

If there is no external shunt applied (which is the default

case) select No. This connects the 2 black negative terminals

together internally.
