Helmet Mounted Lipo Battery Booster *Source Files Included*

I made this because I have a helmet cam and bluetooth communication device that both have about 3 hours of battery but I can ride for 12 hours easily in a day. I wanted something mounted to the helmet so that there was no wires running elsewhere.

I got some of these off Ebay: https://www.ebay.com/itm/18650-Lithium-ion-battery-5V-1A-2A-Dual-USB-LCD-all-in-one-boost-Charger-Module-/322373666333?hash=item4b0ef7c61d

This uses that module and a lithium polymer battery pack like this 2000mah
