Motorsport Lithium Battery

Super B Andrena 12V25Ah Lithium 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. It is a 12V lithium iron phosphate battery, delivering 25Ah (320Wh) of capacity for reliability, high performance and results. Designed in a standard rally casing, the Super B Andrena 12V25Ah Lithium Battery is specifically made for setups that have larger engines or ones that run more electronics, including those of motorcycles, off-road vehicles and cars.

Why Choose the Super B Andrena 12V25Ah Battery

As the Andrena 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 Andrena 12V25Ah Lithium Battery is maximised. With lithium iron phosphate (LiFePO4) technology, combined with its waterproofness, it is the safest and most reliable battery on the market.

Lightweight Power

The Super B Andrena 12V25Ah Lithium Battery is compact in size, measuring in at 249 x 96 x 141mm and weighing 4.3kg, 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 Andrena 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 Andrena 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.

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.

Safe & Reliable

Due to its LiFePO4 technology, which is renowned for its thermal and chemical stability, the Super B Andrena Battery is amongst the safest lithium technologies on the market. As well as the technology, the Andrena Battery casing is made from PC-ABS with an ingress protection rating of IP69. These features make the battery completely dust-tight and waterproof, which is ideal for extreme motorsport environments.

3-Year Warranty

The Super B Andrena 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.
