The all new Autosport International Award Winning Lithiumax RESTART9 Bluetooth battery. Weighing just 3.9kg the NEW 5th Generation 'Bluetooth RESTART' Series 900CA Lithiumax LiFePO4 Car Battery with RESTART technology (1000A pulse discharge for 3 seconds).


Market leading 68Ah PbEq lead-acid/AGM/GEL equivalent capacity, 23Ah Lithium nominal. RC rating of 130mins at 25 degC – suits 4, 5, 6, 8, 10 and 12 cylinder engine cars, 4WD, bikes, boats & aircraft up to 6.5L displacement.


Replaces your standard Lead-Acid or AGM/GEL battery at only 20% of the weight and charges using your vehicle, boat, powersports, light aircraft standard alternator/generator up to 200A or up to 100A using a stand alone AC/DC or DC/DC charger. Lithiumax batteries were designd in Australia specifically for cars, SUVs, 4WDs, boats, bikes, powersports and aircraft from the ground up. Compare our Ah ratings with the others.


Suits all modern Stop-Start systems. With stable lithium LiFePO4 chemistry technology and industry leading Ah capacity ratings, Lithiumax is all about endurance and long service life. Includes our on-board Battery Management System (BMS) to manage and protect your battery, along with Bluetooth battery monitoring and Restart control from the Lithiumax App, available on Google Play and the App Store. 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, 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 is 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.

  • Waterproof to IP65 Environmental standards

  • Shockproof 

  • Direct drop in replacement compatible with all 14V–15V charging systems and alternators 

  • Battery Monitoring BMS System onboard – manages input and output current, charge, cell balance, temperature and RESTART

  • Flat discharge curve 2000+ discharge cycles vs 500 for lead-acid or AGM/GEL 

  • Higher average voltage. Much more linear power than Lead-Acid or AGM/GEL

  • Safe, non volatile 

  • Environmentally friendly, organic compounds 

  • 5–10 year usable life span

  • Replaces lead/AGM/GEL at only 20% of the weight 

  • Quicker starting with a full 1 volt higher than lead/AGM/GEL and less voltage drop during cranking

  • Improved engine management & data logging performance with more stable voltage

  • Less horsepower loss from the alternator due to efficient charging, 4 times faster than lead-acid/AGM/GEL!

  • Note: Bluetooth batteries do have a drain due to the Bluetooth modules constant operation and will require periodic charging. The App will assist in assessing the frequency of maintenance charging required.
