BYD Lithium Battery
Sunsynk have produced a perfect storage solution. The module consists of Lithium-ion phosphate rechargeable batteries with 5.12kWh capacity rated at 51.2V 100Ah with a built-in battery management system.
The battery can be expected to remain serviceable for more than 10 years and this takes into consideration that it is charged and discharged once per day at room temperature (25°C).
Lithium-ion phosphate batteries provide excellent thermal stability and storage. The module also incorporates a self-monitoring function for the detection of any abnormalities in power storage.
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.
