Bluetooth App | Control Screen - Explained:
The Bluetooth app offers the ability to control the charge or discharge loads from the battery by remotely switching ON / OFF the power via the Bluetooth App.
To turn either your charge or discharge loads off, simply switch the blue toggle (blue = ON) to instead show a blacked out toggle.
CHARGE SWITCH - to remotely disconnect all charge loads from the battery. Turning this particular switch OFF will prevent the battery from taking a charge load from any charging source, including the DC battery charger.
DISCHARGE SWITCH - to remotely disconnect all discharge loads from the battery. Turning this particular switch OFF will prevent the battery from running any appliance as it disconnects all loads from the battery. This is the perfect option to use when storing the battery.

Low Voltage override |
Yes, available through push button on side of battery Pack Labeled "Push for Low voltage override" Note: When using low voltage override, it is recommended to install the TUR-L under bonnet isolator to ensure isolation from main start battery will occur. Low voltage override removes the isolation feature in the DC battery charger. |
Charging:
The Thumper 120 AH includes the complete vehicle wiring loom (TUR-L) - 8mm wiring. The wiring loom is designed to separate the Thumper from the main starter battery when the vehicle ignition is off. It is recommended to still install this loom with models that are fitted with the DC charger.
The TUR-L charging loom has been equipped with an ‘ignition wire’. This ignition wire has been designed to work in conjunction with the Thumper models fitted with a DC charger and a ‘Low Voltage override switch’. This switch is designed for use with vehicles that have a low output voltage. By pressing the ‘Low Voltage override switch’, the switch will illuminate BLUE, and DC charger will begin to charge immediately when the vehicle is running. The DC charger will cease to operate as immediately when the ignition is OFF. This isolation occurs from the TUR-L and not from the DC charger when the ignition wire
If the ‘Low Voltage override switch’ is not illuminated, then the DC charger will be allowed to operate as normal by voltage. This method allows the main starter battery from the vehicle to require a minimum of 13.2 Volts in order to activate the DC charger. When the vehicle is OFF, the main starter battery will need to reach a voltage of 12.7Volts before the DC charger will switch OFF and isolate.
