I'm trying to identify the issue with my portable monitor. While testing it I noticed a weird (at least for me) thing that I can't understand.
I set voltage on my power supply to be exactly 7.2V. When I measure it on the power supply terminals it indeed shows 7.2V. Now when it's measured on the battery connector (where I inject the voltage) it measures only 6.8V.
Does it mean there is a voltage leak to the ground? I'd expect my power supply to show 6.8V on the screen but it shows 7.2V as set.
