High Voltage Stackable Energy Storage System LiFePo4 Battery 10kWh 15kWh 20kWh 25kWh

Compact Stack Design: 5kWh/102.4V per module. Flexible capacity expansion from 5.12kWh to 25.6kWh.
Easy Installation: Plug and play, no extra wire harness connection, maximum flexibility and ease of use.
Safety and Reliability: LiFePO4 cells for greater safety and longer battery cycle life, up to 6000+ cycles at 80% DOD 0.5C.  
Built-in smart BMS offers voltage, current, temperature protection and alarm functions. 
Higher Power Output: Deliver more power to the home appliances and devices, especially those that require high surge currents or fast charging.
Faster Charging: Charge faster from the grid or from a solar system, as it requires less current for the same power input. This can shorten the charging time and increase the energy availability.
Reduced Weight and Size: Reduce the weight and size of the wires, cables, connectors, and other components needed for the battery system, as they can handle less current for the same power output. It greatly improve the installation, safety, and cost of the battery system.
