stern asked May 16, '24

Hello, I got a Lithium 16 cell battery. I use MP battery monitor at the moment and have standard settings and ESS:

Problem:

-The SOC is at real 20% from the BMS but here it is:

-Means it drops until low voltage alert with 47V but still has 85% SOC. What configuration did I do wrong?

- Whatever I do, i can load only with 500W max, although I do not limit charge power. What is wrong here?

Thank you

my settings are:

changing this seems to me improving long time measurement. I am missing a ways to tell the MP

-now, that the battery is in undervoltage condition, please assume <5% SOC instead of 90%
