Product Description

Polarium Battery SLB48-250-146-2S

Introducing the Polarium SLB48-250-146-2S lithium-ion battery module, a cutting-edge energy storage solution renowned for its exceptional efficiency and high power density. Engineered in Sweden as a dependable backup power system, the Polarium lithium-ion 48V / 250Ah  battery module is equipped with a range of innovative features that prioritise safety, simplicity, durability, intelligence, security, and sustainability. Trusted by critical infrastructure organisations throughout Australia, Polarium batteries ensure unwavering power support that you can count on.

Safety First
Your safety is top priority. All Polarium products undergo rigorous testing and certification to guarantee secure and worry-free operation. In addition, the Polarium Current Limiting Device (CLD) protects the battery module under a range of conditions. The battery will never overheat and give way to thermal runaway. You can be rest assured, you have the safest battery on the market.

Effortless Operation
Harnessing advanced technology has never been easier. Polarium batteries are designed for straightforward installation, effortless use, and require minimal maintenance for optimal performance and charge control.

Rugged Reliability
Capable of thriving in diverse conditions and environments, Polarium batteries offer added protection against dust and moisture, extending their operational lifespan.

Intelligent Functionality
Experience the convenience of active balancing, blackstart, and the flexibility of local monitoring via Bluetooth, among other intelligent features.

Unparalleled Security
With Polarium's exclusive Anti-Theft Device, you are assured of the utmost security. In the event of removal from the site, this patented feature disables battery functionality, and for added peace of mind, an optional GPS tracker can be incorporated.

Eco-Conscious Sustainability
