Monitors real time battery voltage, current draw, battery temp at core and skin as well as remaining capacity.


RESTART technology that hard-cuts power at a safe voltage. Your battery can then be restarted by pressing the button on the App or on-battery, leaving enough energy in the battery to start your engine. A fixed hard-cut at 8V is also there to protect your battery from over-discharge. Due to the Bluetooth module’s constant operation, periodic charging to maintain this battery may be required.


Lithiumax's revolutionary new RESTART batteries are also protected from over-charge as well as over temperature.


Direct drop in replacement for lead-acid or AGM batteries for cars, 4WD motorcycles, powersports, light aircraft or boats inc standard brass multi-angle terminal blocks with 6mm (M6) bolts.


SAE type terminal posts also available from this website under 'Connectors and posts'. Aluminium race mounts as well as OEM fitting kits are also available under accessories in either flat or upright mount form.
