Hi all! I'm new to the forums but didn't have any luck searching for results for this.

I was attempting to use the boards "P2" solder pads to break out power for some custom accessory and while it measures out to full power from pin 1 to 5, when the load is applied it drops to 1.0V and I cant seem to determine why.

Any advice? or will I just have to break off power from the battery leads?
