Sunsynk L5.1 Battery
Sunsynk have produced a perfect storage solution.
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.
Don't forget to fully charge your batteries upon installation.

Trouble Shooting
When SoC drops 0% and the communication could not be established automatically.
Why sometimes the SoC will not achieve 100% or 0% at the end of charing or discharging.
Why the master pack suffered seriously under-voltage.
How to wake up the battery.
Beeping at the end of charging stage (99%-100% SoC).
