1.28kWh lithium battery for compact backup power
The Esener 1.28kWh lithium battery provides 100Ah of storage at a nominal 12.8V for small backup and solar power systems. Its battery management system provides current limiting and protection against overcharging, over-discharging and excessive temperature.
Wall or shelf mounting gives you a choice of installation positions, while low self-discharge helps retain stored energy between uses. USB and 12V DC outputs provide connections for suitable devices, alongside the AC output. Series and parallel expansion supports a maximum 2S2P configuration. For an external inverter or charger, use equipment suitable for the battery's voltage, charging requirements and current limits.
The battery-level indicator is approximate and must not be used as a precise measurement of remaining capacity.
