  1. 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

  2. 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
