[Solved] Battery not powering Feather M0

Projects General Guidance
1

Hello, I have a 3.3v Feather M0 basic proto and the 3.3v battery will not power the device.

  • The charge light is on when both the USB and the battery are connected.
  • When I disconnect the USB the battery does not auto-switch and take over powering the Feather.
  • Testing the battery yields a 3.92v charge exists.

Does anyone know what to check next?

The battery is connected via the JST connector. Thank you for the reply.

Please check the red and black wires. I just saw another picture of this board (or a clone) that had them wired the other way around!

This photo confirms that the orientation spline does face up.

Some rechargeable LiPo batteries from eBay have opposite wiring!

Had to swap mine to get it to work on my Feather compatible board

Thanks reversing the wires did indeed work!
