Motorsport Lithium Battery

The Super B Mason 12V25Ah Lithium Battery delivers lightweight, high-performance power, designed specifically for motorsport and high-demand 12V systems. The Mason 12V25Ah battery equals a lead-acid battery of 100 to 130Ah, provided the alternator’s maximum current doesn’t exceed the battery’s maximum charge current of 77A.

Why Choose the Super B Mason 12V25Ah Battery

As the Mason Battery is very lightweight and compact, it can fit with ease in any vehicle and eliminates the need to constantly check on it due to its low maintenance features. The fast-charging aspect of the battery, combined with the minimal self-discharge rate, means that the battery life is long-lasting and quick to refill, ensuring that usage of the Super B Mason 12V25Ah Lithium Battery is maximised. With lithium iron phosphate (LiFePO4) technology and integrated BMS, combined with its water resistance, it is the safest and most reliable battery on the market.

Integrated BMS

The Super B Mason 12V25Ah 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 & Reliable

Due to its LiFePO4 technology, which is renowned for its thermal and chemical stability, and integrated BMS system, the Super B Mason Battery is amongst the safest lithium technologies on the market. As well as the technology, the Mason Battery casing is made from PC-ABS with an ingress protection rating of IP66. These features make the battery completely dust-tight and resistant to water, which is ideal for extreme motorsport environments.

Lightweight Power

The Super B Mason 12V25Ah Lithium Battery is compact in size, measuring in at 255 x 101 x 171mm and weighing 5.2kg, so it is perfect for vehicles that need a smaller power source with high energy capacity.

At only 1/3 of the size of traditional lead-acid batteries, the Super B Mason 12V25Ah Lithium Battery not only simplifies maintenance and installation in tight engine bays, but it also improves fuel economy and performance, delivering sharper handling, quicker acceleration and less strain on suspension components.

High-Performance

The Super B Mason 12V25Ah Lithium Battery delivers exceptional power with a stable and flat discharge curve, meaning over 80% of its capacity is usable. It supports high continuous and pulse discharge currents, making it ideal for demanding motorsport applications, including motorcycle, automotive and marine applications.

Fast charging in as little as 25 minutes minimises downtime, while a long cycle life of over 1,000 full discharges ensures reliable, maintenance-free performance. With a self-discharge rate of less than 3% per month, the battery holds its charge for extended periods, allowing vehicles to remain unattended much longer than with traditional lead-acid batteries.

3-Year Warranty

The Super B Mason 12V25Ah Lithium Motorsport Battery comes with a 3-year manufacturer warranty and support from Aim Shop’s experienced technical team for your peace of mind. Super B provides batteries that have been engineered and tested against the harshest of environments to ensure high performance for years to come.
