Introducing LITE↯BLOX feather-light flagship model for use in highly combusted motorsport vehicles according to FIA.

After many years of development and extensive field tests with selected partners in professional motorsport, LITE↯BLOX now offers their proven LITE↯BLOX product series as a special version for strictly racing applications.

The technology-leading LITE↯BLOX LB MotorSport accumulator series has been developed in close cooperation with a large semiconductor company to fit automotive standards and comes with an additional DEUTSCH Autosport connector including motorsport harness by DC electronics, enabling full integration into the vehicle’s CAN-bus system.

Using state-of-the-art semiconductor elements coupled with a powerful microprocessor, the LB14XXMS provides comprehensive & accurate telemetry recording (current, voltage, temperature) over the entire race distance, supporting fault diagnosis in the vehicle periphery – either via CAN bus or integrated wireless interface (smartphone/tablet).

Each battery is totally hand-finished into a stunning carbon fibre shell – Handmade in Germany.

LITEBLOX batteries are suitable to be powered by conventional alternators and replace your standard starter battery as a plug ‘n’ play solution with less volume and weight for various applications in motorsport & performance cars:
LITEBLOX batteries are so safe, they can be used inside the car and are approved for motorsport applications worldwide.

Most likely the lightest car battery in the world

The lightweight LiteBlox batteries offer decisive advantages over common competitor products:

  • saves 13-18kg (28-40lbs) to the standard starter battery
  • Plug’n’Play replacement – fit for almost any production car
  • maintenance-free due to intelligent BMS-System (over-/undervoltage, over-/undertemperatur, overcurrent & short circuit)
  • full replacement for conventional circuit breaker systems with “solid-state” technology (CARTEK, ARMTECH) in a holistic solution, without additional motorsport harness
  • wireless interface for wireless data monitoring via Smartphone App (can be deactivated)
  • innovative & smart electronics for power off-switch via Smartphone App in two different programs:
    1.) I.K.O.S. – Intelligent power off-Operation-Switch:
    effective disconnection of the LITE↯BLOX from the vehicle due to overload or via Smartphone (emergency or extended sitting periods), similar to the common FIA all power-off switch
    2.) A.V.A.T. – Active Vehicle Anti Theft: while all consumers are still being provided with energy, the LITE↯BLOX will instantly shut down at any theft attempt
  • latest premium cell technology (A123 ANR26650M1B V3)
  • rapid charging (ideal for Start-Stop)
  • marginally self-drain when not in use (sitting time >250days)
  • fail-safe due to innovative concept and premium materials
  • DMSB homologated (Lithium-Ion battery RLB2016-27/17)
