Can't find my switches so we'll have to do without and only managed to secure 3 mini USBs for the chargers. People will have to source their own.

Sourced enough headers for soldering tomorrow

Soldered the circles and Lipo chargers before the previous comment was added! I didn't have a set of male to female dupont connectors, and have had to cut female ends from the headers in order to use female to female ones in some cases (not ideal).

I can buy some more poppers tomorrow to use as switches
