Electron : fast red blink when Vin connected without LIPo

Hello @mohit,@BDub,@ScruffR,@RWB it has been 7 days now since my last findings and I never heard back from any of you except to

which I do not want to do. So I guess the short answer to my question of "Open to more ideas to try" is to wait for a possible firmware update.

While I have your attention I want to ask your collective thoughts on another possible solution. The whole premise of connecting to VIN and avoiding the LiPo battery is that the Electron will be located in a location where charging a LiPo battery is not an option and changing LiPo batteries is harder than replacing four AA batteries. The location is indoors so solar is not an option.

Would the following scenario work:
Keep the LiPo battery plugged in but also connect the four AA batteries to VIN. When the LiPo battery starts to draw down power would it take power from the AA batteries to charge up and then leave the AA batteries alone until the next LiPo draw down? The idea being the LED problem is solved, I leave the LiPo in place and only replace the AA batteries when needed which is the practicality that I need. Or does VIN act like batteries being plugged into the USB port and totally powering them down before drawing power from the LiPo battery, as mentioned in the Electron Power Management on Four AA Batteries post?

I would love to get a workable solution to this problem.

Thanks
