Mason 12V25Ah

The Mason 12V25Ah lithium battery is light-weighted, compact and offers high performances. Thanks to its lithium-iron phosphate technology and integrated BMS system this new generation battery is extremely reliable and offers optimal safety. This battery is developed for motorsport, motorcycle, automotive and marine applications. Suitable for 12V systems and for use in extreme environments.

Lightweight Power

With a weight of only ±5.2kg /11.46lbs, the Mason 12V25Ah lithium battery saves up to 80% in weight in comparison to traditional lead-acid batteries and is only 1/3 of the size of a conventional battery. This improves not only the performance of your vehicle but also helps to increase the fuel economy.

The battery offers a high level of power, fast charging and a long, maintenance-free service life. It also has a stable and flat discharge which means you have over 80% of the batteries capacity available.

Integrated BMS

The Mason 12V20Ah lithium battery incorporates a Battery Management System (BMS) to ensure a high level of safety during use. The BMS constantly monitors the status of individual battery elements such as cell temperature, cell voltage, charge and discharge currents. The integrated BMS also provides cell balancing.

Safe and reliable

Due to its high ingress protection class (IP67) the battery is dust tight and waterproof. Therefore the battery can be used in the most extreme environments as well.


Super B batteries do not contain lead. The LiFePO4 technology is an environmental-friendly energy storage solution.
