Continued from previous post... Voltage up to 4.02. And finally reaching 4.19. After being at 4.19, the board continues to run, but the charge light goes out. I think when the light is out, it might still be trickle charging to the battery, with constant voltage and lowered current. I say this, because the reported voltage on the voltmeter was still 4.19, yet when I unplug the USB charger from the wall, I get this drop to 4.17 volts. It is also possible that drop is simply from the load of the board on the battery. Either way, it shows that the batter

A little more hackery and results regarding the batteries... Note/Reminder: We are dealing with raw LiPo batteries (no built in battery management system (BMS) protection circuit). These are a dense source of energy. Fires, explosions, and toxic fumes are possible. Don't cross the streams! (don't short circuit the positive and negative tabs on the batteries) I ordered an Adafruit Feather HUZZAH (https://www.adafruit.com/product/2821). This can run off a 3.7/4.2 volt LiPo battery, like our phones do. And, more importantly, it has a smart charging circuit, so it can charge th
