12 Volt Charging: (TUR-L NOT included in this listing)
The Thumper 90 AH is usually included with a complete vehicle wiring loom (TUR-L) - NOT INCLUDED IN THIS PACKAGE - replaced with In line DC 8 Amp
TUR-L (not included) information:
The Thumper 90 AH normally includes the complete vehicle wiring loom (TUR-L-8mm). 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.
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.
The In line DC 8 Amp Charger (Included in this package instead of TUR-L)

This charger is solely designed for the use with LiFePO4 Lithium batteries.The charger has the ability to reactivate Lithium batteries that have shut down the BMS system with a low voltage disconnect.
