Description

Product Description

The Esener 2.56kWh Low Voltage Battery is a high performance lithium battery designed for residential backup power systems, small solar installations, and off grid energy storage. Built with high quality lithium prismatic cells, the battery provides stable energy delivery and long service life while maintaining a compact and durable design.

The unit includes an advanced Battery Management System that protects the battery from over charge, over discharge, over current, and temperature related issues. This ensures safe and reliable operation while extending battery lifespan. The battery is compatible with many 24V inverters, solar charge controllers, and lithium battery chargers, making it suitable for a wide range of solar and backup applications.

Its robust steel casing allows for wall mounting or shelf installation, and heavy duty side handles make handling and installation easier. The battery can also be expanded through parallel or series configurations to increase storage capacity for larger energy systems.
