The Thumper 40 AH includes the complete vehicle wiring loom (TUR-L).
The wiring loom will allow for the Thumper Lithium pack to charge from the vehicle whilst driving and will separate from the main starter battery when the vehicle ignition is off.

This particular kit does not include a DC charger.
The Thumper Lithium will charge perfectly within most vehicles without the use of the DC charger,
providing the following conditions are satisfied:

The vehicle must have an output of approx. 13.8 Volts (Voltage output below this point would
recommend the use of a DC charger).

  • The TUR-L must be installed.
  • It is recommended to charge from 240 Volt every 6-8 weeks to ensure battery reaches full capacity.
