Esener 2.56kWh Multifunctional Lithium Battery 25.6V

2.56kWh lithium battery with USB, DC and AC outputs

The Esener 2.56kWh lithium battery combines 100Ah of storage at a nominal 25.6V with USB, 12V DC and 220V AC outputs. This multifunctional unit provides connections for suitable small devices, with the AC output rated at 300W.

Wall or shelf mounting gives you a choice of installation positions, while side handles assist with handling and wall mounting. An integrated battery management system provides voltage protection and current limiting, together with protection against overcharging, over-discharging and excessive temperature. Low self-discharge helps retain stored energy between uses.

Series and parallel expansion supports a maximum 2S2P configuration. External charging options include a suitable 24V inverter, lithium battery charger or solar charge controller. Select charging equipment and settings that meet the battery's voltage and current requirements; do not assume compatibility from nominal voltage alone.
