Australian BUILT - Australian OWNED - The Thumper range is designed to take the place of, or even work alongside a dual battery system in the vehicle. The units are supplied with a charging system for the vehicle or boat, which when installed correctly, will allow for a recharge time of 2 – 4 hours.
Each Thumper unit consists of multiple 12 Volt AGM cells (Absorbed Glass Matt) linked together in parallel. The cells are maintenance free and will not leak or gas when charging; perfect for use inside the vehicle or enclosed areas.
You will have absolute peace of mind when jump starting with your Thumper as the entire range is ‘spike protected’. This means that no damage will occur to any in built computer systems.
