Battery Charger C.stl should be printed in Vase / Spiralize Mode
Battery Charger H.stl should be printed without supports and is an easy print. It holds 18650 Lithium Ion batteries snugly and you will want to push in the wires through the holes BEFORE squeezing the batteries in as they are very hard to take out again.
This allows wiring up batteries without having to weld the batteries as the connection is held securely.
The circuit diagram helps switching the batteries from series to parallel. So we can put them in parallel for charging and series for usage at 2X Volts.
Use at your own risk of course.
Please be safe and smart when handling Lithium Ion Batteries.
