ECS2900-H5 battery charge level

[fumbo]

Hello, I'm wondering why the charge level with the LED lights on the battery is not the same in the application. When the battery is charged to 100%, it is also 100% in the application. But when it is discharging and it is 80% in the application, the LED still shows 100%. Why such a big difference. I have a Foxess inverter H3-12.0-E 12000w and a battery ECS2900-H5 14400w. Thanks for the explanation and all the best

The LEDs only give a very coarse indication of SoC.
From the ECS manual:
