The new State-of-the-Art LITHIUMAX DEEPSTART100 Bluetooth Dual-purpose deep-cycle and engine starter battery is a revolution in lithium battery technology. The Lithiumax DEEPSTART100 Bluetooth is the ultimate battery available anywhere at any price with 1200CCA and 1400CA with 100Ah of Lithium capacity, the equivalent of a 200Ah AGM or lead-acid battery (PbEq). The DEEPSTART100 case size is optimised for under bonnet, in cab or in canopies, trailers or caravans the DEEPSTART100 is the perfect on or off-road deep-cyle energy storage power supply with powerful engine starter capability. Dimensions are N70ZZ MF or 305mm x 172mm x 224mm (inc terminals) with left side +ve terminal orientation. (Note: for Right side +ve terminal orientation or N70ZZL see RESTART100). The DEEPSTART100 can be used wherever a N70ZZ MF size or most larger batteries are specified. An optimised footprint, maximum power and capacity and left side +ve terminal orientation the DEEPSTART100 delivers, with an unprecedented power-to-weight ratio inc Bluetooth Real-Time monitoring from the dedicated Lithiumax App.


Simply scan the QR code at the top of the battery to download the iOS or Android App for seamless Bluetooth connection to live battery data on your mobile device, with an extensive range of operation, up to 40 meteres (depending on battery location).


Simply put, if you want the best dual purpose battery money can buy with IP65 environmental protection, then the DEEPSTART100 and RESTART100 are it, the perfect batteries for both on and off-road, 4WD and boat applications.


The Lithiumax DEEPSTART100 Bluetooth can be used under bonnet in road and off-road vehicles and Ah capacity can be expanded by adding the RESTART100 or another DEEPSTART100 unit connected in parallel to double the Ah capacity. Up to 4 units can be connected in parallel. Designed for standard alternator charging though it is recommended that a DC/DC charger be used where 2 or more batteries utilised to minimise the charging load on the alternator. Charging systems delivering between 14–15V optimised.

The Lithiumax DEEPSTART100 Bluetooth is covered by a 3 year no-nonsense warranty.

Advantages of the Lithiumax LiFePO4 Lithium Battery:
  • 'RESTART' safety technology

  • UN38.3 Approved

  • Autosport International Award Winning Technology

  • BMS System with In-built Bluetooth App monitoring

  • Dry cell, no acid, no gassing

  • Splashproof to IP66 standards

  • Shockproof 

  • Direct drop in replacement  for NS40L size batteries compatible with 13V–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.
