Hello,


Did you find a solution?

I‘ve a similar problem with a MP and REC BMS, during discharging from 100-50% all is ok. After that SOC drops to 3% . Voltage is 54v on a 16s what is still good.


Thank you, Peter

check that the battery monitor you are using has the correct battery size set, if its a BMV or mutliplus/quattro unit - if its the batteries BMS being used as the batetry monitor then contact the battery supplier
