Hi,
After the BMS Firmware Upgrade, the Ac200max has only thy capacivity of about 1400 Wh.
I started the Firmware Update after the question with a actual batterie Level of 94. After the Firmware Update it Shows 100 percent.
Since there i have dischared and charched it 2 times completely for calibration.
But no effort.
Hi @uwe1
The BMS Update aims to improve the accuracy of the shown percentage.
So there isnt any loss of of capacity for sure ;)
greetings
Erik
