Product Description

The Esener 1.28kWh Low Voltage Battery is a multifunctional lithium energy storage solution built for small scale solar power systems, backup power setups, and portable power applications. It combines the functions of a solar storage battery, UPS battery, and portable power source in a single compact unit.

The battery uses high quality lithium cells and includes an integrated Battery Management System that protects against over charge, over discharge, over current, and temperature issues. Its low voltage design makes it compatible with many small inverters, solar charge controllers, and battery chargers.

The unit can be wall mounted or installed on a shelf and includes convenient carry handles for easy handling. With multiple output options including AC, DC, and USB ports, the battery can power a wide range of devices such as routers, lights, laptops, and small appliances. The durable steel enclosure and LED display provide both protection and easy monitoring of battery status.
