EggTimer Classic Rev D Beep Code Error

[AWright-001]

Hello, I recently built an Eggtimer classic, and after getting it all assembled it gives the beep code of one high then one low beep, which should be a battery error.
However, with the board configured for variable voltage, and a good 2s lipo that read 7.4v, I am confused on how the battery could be an issue, if the error code truly is pointing to the battery.
I was able to get into the boards programming, however the flight profile did not save after powering off and reconnecting. All of the solder joints look okay, so I am not fully sure what could be wrong.
Any help would be greatly appreciated.

Did you hit the ESC key after you made your changes? That saves them... it's not dynamic.

Also, did you do a memory initialization (CTRL-Y from the menu)?

Thanks for the reply.
I did a reset before and just did another one. Same error code of one high beep then one low beep on repeat. The battery has a nominal and measured voltage of 7.4v so I don't see how that could cause a battery issue.

Check the 3.9K and 1K resistors... you may have them reversed.

Those two are in the correct position.

Here's pictures of the board if that helps
