Problems powering HUZZAH esp8266 board

[gunglefunk]

When I power the board via FTDI cable everything works as expected. I can flash firmware, upload code, run programs, etc. However, when I try to remove the FTDI cable and just power the board via batteries or bench power supply nothing seems to work. I hook power up to VBat and ground to ground but nothing seems to happen. The bench power supply shows a drop from 5v to ~1.3v and there's no indication that anything is running (no LED flashy, program doesn't appear to execute, etc.) I bought 5 of these boards at once and they all seem to exhibit the same behavior, so I seriously doubt it's a hardware problem. Any idea what I'm doing wrong?

Post a photo showing your hardware and connections for one setup and we'll take a look. 800x600 images usually work best.

As it turns out, a couple things were wrong on my end. The battery pack I was using most likely wasn't able to supply enough current for startup, and my power supply was set wrong. Once I figured out that part everything started working as expected.

Glad to hear it's working for you!
