Sunsynk L5.1 Battery

Sunsynk have produced a perfect storage solution.

Modern Wooden House

SUNSYNK-L5.1 lithium-ion phosphate battery is one of the new energy storage products developed and produced by SUNSYNK. It can be used to support reliable power for various types of equipment and systems. SUNSYNK-L5.1 is especially suitable for application scenarios of high power, limited installation space and long cycle life.

The energy storage module includes lithium-ion rechargeable batteries with 5.12kWh capacity, and the controller enables a central of multiple modules. Thus, batteries can be connected in parallel to expand capacity and power for applications that require larger capacity and longer power support. SUNSYNK-L5.1 has a built-in BMS (battery management system), which can manage and monitor cell-battery information, including voltage, current and temperature. Moreover, the BMS can balance cells charging and discharging to extend cycle life.
