Voltage from BMV 712 incorrect - fuse size of temp sensor?

Hi all,


I read about incorrect voltage readings from the BMV712 when there is by mistake a 100mA fuse instead of an 1A fuse in the power cable.

I got an optional temperature sensor connected on my BMV and there is a 100mA fuse in the power cable. Does the fuse size have to be 1A also?


I didn't find a information about it.

It is a safe bet to use the 1A fuse as what the fuse is protecting is the same.

I'm asking this question cause I got different voltage data from my solar charger mppt 100/50 and the BMV 712 and I got an hint here at this community regarding wrong fuse sizes shipped from factory which causes these issue due to a wrong resistance.

So it is quite important to know the 100% correct fuse size, not for protecting the device as for getting correct values.

So please don't bet and answer if you know the correct values. Thank you :)
