For the mbot2 Neo, what is the voltage of the 100% charged external battery?

Hi, The mbot 2 Neo has a port for an external battery. What is the voltage of this external battery when the battery is 100% charged? Regards

#2

Around 3.7 volts

I am surprised about this because my battery nominal voltage is 3,7V.
When my battery is fully charged, it is 4,2V. My battery is brand new.
But here is what the mbot 2 neo shows when I plug my battery fully charged (multimeter also shows 4,2V):

only 1 bar and in red color (I even have 4 different batteries and the screen shows this for all of them)

@Rosco Nope. That’s the nominal voltage.

@kris When the battery is fully charged, it should be about 4.2 volts.
Can you find the version of your CyberPi firmware (in Settings)? Thanks!
