3D print a case for the updated Micro Lipo Charger V2!

This features 5V input for charging single Lithium Ion/Lithium Polymer batteries. And it ships with a free JST cable.

The new V2 version features a built-in slide switch so you can easily switch between the two charging rates.

3D print the two halves in your favorite filament. Use translucent PLA to make it look like those clear enclosures from the 90’s.

The JST connectors are covered to help keep out any dust and to provide a bit of protection.

Rate switch

Flip the slide switch to chose between High or Low charge rates.

Check out this guide for more about selecting the right charge rate for your battery!

The PCB has pads for USB so you can plug it directly into anything with a USB type A socket.

It features charging status LEDs so you'll know when your battery is fully charged.

Protective Case

 

The PCB sits over the bottom half and the top snap-fits over the sides.

The case features a cutout for the built-in slide switch so you can still access it to adjust the charging rate.

This supports all of the Adafruit lipo batteries so you can safely swap between the different types.

For all the technical details, be sure to check out the product learn guide.
