Issues with V4 Board - Need help

So it appears I'm having issues with assembling this project. The first time through I followed the assembly guide, and after assembly I went to turn it on, and the device would start to boot and then randomly turn off during boot. Eventually after a few boots the device would no longer turn on.

I disassembled the entire project and determined the pi zero I had was no longer booting properly. I ordered a new pi zero this time, and started assembly again, this time testing each step of the assembly stage by booting the device.

Before assembly I made sure the new pi zero worked and loaded an sd card with retropie. It properly booted. I then attached the pi zero to the V4 board and tested the pogo pins with the multimeter. Worked fine. I booted the pi with it attached to the unsoldered unit and it successfully booted. I then soldered the board, again tested with the multimeter. Turned on the pi zero, and it then suddenly started randomly rebooting, like it had done with the previous pi zero. At this point I'm not sure what I'm doing. I'm confident of my soldering skills and it looks fine. 

It was also tested with a known working USB cable and 2A power source.

I've attached a picture of my solder job. Could you please help me out? 

 

Thanks!

When you tested with the 2A power source, was that after soldering to the board? If not, are you able to try powering it straight from the Pi's USB port? I recommend disconnecting the battery before doing this.

Thanks for replying.

When testing with the 2A power source, I connected it directly to the USB port on the pi zero. Before soldering it worked fine, but after soldering it started to shut off randomly during boot. The battery was disconnected during the test.
