The ThunderBox not only extends battery life, but protects the bike's electric system from overloading and short circuits. The ThunderBox can operate in three different modes.
Depending of the connection of the WHITE control wire the following modes can be acquired. 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.
The TB will switch the outputs ON/OFF (with a few seconds delay) following the ignition key switch position. 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. 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. 24 HOUR SERVICE IS FOR ORDERS PLACED BEFORE 2PM, MON-FRI ONLY AND EXCLUDES BANK HOLIDAYS.
