Arc Badge Battery Mod

thingiverse

Didn't like the AA battery part on the Arc Badge, so decided to swap it out for a lipo instead. Can reuse the screws that come with the badge itself. The 3.3v step down is required because the SAO ports get direct battery voltage straight away. The badge itself has a regulator built-in for the LED functions. The step-down will eventually drain the battery, but we're talking about many weeks, not just a few days. If you're going to store the badge for longer than a week, unplug the battery right away. The button is still super easy to press. Stuck a bit of glue and double-sided tape between the charge board and the button and it keeps it totally isolated. Parts used were: 3.3v step down - https://www.amazon.com/gp/product/B07K8VXYQV Adafruit Lipo Charger - https://www.amazon.com/gp/product/B00MJ0HOKS 2000mAh Lipo - https://www.amazon.com/gp/product/B0137ITW46 Wires and connectors were already on hand.
