BMV 600, can I set voltage offset?

I have an "old" BMV 600, it constantly reads about 0,20V lower than any other testing device I use to check the voltage on the same conectors. This gives me problems detecting "full charge".

Is there a way to set an offset to calibrate the voltage of the BMV600? Or is there any other way to calibrate the voltage?


Obviously, setting a lower level of full charge will get me to 100%, but I’d prefer an accurate voltage displayed if possible as I have Lithium batteries.


Thanks!

Is there a fuse in the BMV power cable & what current rating is the fuse?

A fuse with very small current rating can have enough resistance to cause the issue your seeing.

Thanks Mark, there is a fuse, can I just remove it, or what would be my best option?

Hi @fredrik_wk

You can just remove the fuse and replace it with a 1A slow blow type.
