The ThunderBox is a power distribution module that automatically switches power between the battery and accessories. It is compatible with all vehicles using a 12V battery system, including all motorcycles, cars, ATVs/UTVs, kit cars and even lawnmower trucks. It is available in two versions: 16A (TB-U01) and 2x 16A (TB-U02).
HealTech ThunderBox TB-U01 and TB-U02 are advanced power distribution modules for vehicles using a 12V battery system. They automatically switch accessory power on and off based on engine state and battery voltage, and can operate in automatic, ignition-controlled, or stay-off modes.
The module has a solid-state, fuseless design with reverse polarity and transient protection, IP68 waterproofing, and an operating temperature range of -40°C to +80°C. Installation uses the supplied quick-connect terminal blocks, and LED status codes indicate power, delay, standby, and fault states.
