The current monitor works perfectly. But Volt Monitor doesn’t work.

please share more details like software settings.
maybe your calibration is wrong or the pin is not correctly set

I follow exactly as per here SpeedyBee F405 AIO 40A Bluejay — Copter documentation

Doesn’t work. It’s a new FC. Then after fiddling around. I think maybe because it’s the new firmware

So I install 4.6.0 Still doesn’t work.

Gave up I install Inav. And it work.

Obviously something wrong with the settings.
