Battery & Power Systems

Flat batteries can be inconvenient around town, but downright dangerous when you are travelling to remote locations.

Built to Last

TJM’s battery management systems are the toughest most advanced dual battery management systems available today. TJM’s DC25A allows you to charge your 12V second or auxiliary deep-cycle battery on the go. It is shock, vibration and dust proof, plus water resistant which makes it suitable for both in-vehicle and under-bonnet installation. Offering a host of features, the DC25A can charge simultaneously from both solar and alternator (9-32v) inputs, and function as an MPPT solar controller with dual charging modes for compatibility with both smart and conventional alternators. It comes loaded with a host of safeguard features including over/under voltage, anti-sparking, reverse connection and over-temperature protection systems for peace of mind. TJM’s DC25A is the easy to install and sets a new benchmark for DC-DC battery management.

We've got you covered

If you need to add a second battery under bonnet, then we have got you covered. Precision design ensures your battery is securely housed and mounted under-bonnet in the best location. Superior structural strength is provided thanks to construction from 2mm thick sheet steel and strategically placed folds and MIG welds. A premium black powder coat surface provides excellent resistance against corrosion. Discover the best, with TJM’s precision engineered battery trays.
