Hello, I was trying to power up my D5100 with external 8V but it failed:(
Patch for non-branded battery was already applied.
For power source I was using laboratory power supply with regulated output voltage 1-12V/0.01-10A tuned to 8V/5A.
When I connect PS terminals to P- and P+ on booster, I saw that woltage drops to 5V and no current draw, also camera didnt switch on.
Here is some pics:
Tuned 8V on PSU:

Maybe I missing something? Need some help.
