The ThunderBox not only extends battery life, but protects the bike’s electric system from overloading and short circuits. Get your power issues sorted – lightning fast!
Quick and simple to use
Connect the TB directly to the battery terminals and decide whether you want a fully automatic or ignition key controlled operation. Connect the auxiliary equipment fast, conveniently and safely to the tool-free terminal blocks supplied. Just plug in the wires and you’re good to go!
Multiple working modes
The ThunderBox can operate in three different modes. Depending of the connection of the WHITE control wire the following modes can be acquired: Automatic mode: When the engine is started and runs evenly, the TB switches the power outputs ON.
When the engine is stopped, after a few seconds the TB switches the outputs OFF.
Ignition-controlled mode: The TB will switch the outputs ON/OFF (with a few seconds delay) following the ignition key switch position.
Stay-off mode: The TB will not turn the outputs ON even when a battery charger is connected. This is useful during winter storage as a trickle charger won’t activate the TB.
The TB constantly monitors the battery voltage, engine state (running/off) and the outputs, then switches the loads on/off automatically. The TB isolates/disables the power supply to the accessories until the engine is started and running smoothly, ensuring 100% battery power is always available for starting. This is a fully automated process, resulting in trouble-free starts and enhanced battery life.
Small but tough
We use only the best components and technology to create products that can withstand the harshest environments. The TB has no moving parts, no relays and no fuses. Inside the rugged plastic case the circuitry is encased in epoxy resin, which makes it fully oil and water resistant, shock and vibration proof.
Compatible with ALL vehicles using a 12V battery system (all battery types and capacities are supported), including all motorcycles, cars, ATVs/UTVs, kit cars and even lawnmower trucks.
A weatherproof USB charger is available separately (part no.: TB-USB1) so that power to your USB devices will be turned on/off automatically and protected too. You may connect multiple USB chargers to one TB unit.
