I have a Multiplus, Cerbo and a custom BMS connected to 4 Tesla Model S modules that I'm currently bench testing. I wanted to validate that the Multiplus would still disable the output if the BMS for some reason failed to reduce the discharge current at the low voltage level. The battery voltage is currently displaying at 43.78V and the Multiplus has been configured to cut off at 43V, however it is already displaying an alarm and has cut off.
Can anyone shed any light on this please?
