      I left it charging for more than 2 hrs. Looks like battery still at 3.83v. I see charging battery anim on screen but doesn’t appear to have charged the battery.

      When I unplug usb power and try power switch it will not turn on. No led lights on Zumi board or pi zero.

      I’m not reading any V at switch or I2c on Zumi board. Any suggestions for troubleshooting?

        @robolink_leila Hi Leila, I think Arnold said he found that the battery was the problem. We found that one of the battery leads wasn't soldered. If anyone else gets this problem they could open the tape and see if both battery leads are well soldered.

          @tawnkramer ,
          I've talked to @robolink_arnold and this has been logged. This board seems to be defective, we'll be in contact for a replacement.

            I think I could fix this by soldering battery pins a little further down into plug. Do you guys want to see this failure case or can I attempt to fix?

              No voltage measure here across battery input looks like connection problem at the plug.
