Battery Charger Case 1s 18650

thingiverse

Fitted with springs, wires, connectors, solder, and hot glue, you can charge your 18650 batteries using a 1s charger. Solder the wires to springs that fit into holes, load them in place, and then run the wires through smaller holes. Secure the springs in position using hot glue. To indicate polarity, I covered the hot glue/spring pockets with old rafts - one red, one black. I designed this charger to work seamlessly with existing molex 1s connections for a friend. When paired with a Hitec X4 Micro Multi Charger, you can charge four batteries at once - even if it does take some time. This tiny Whoop charger is perfect for the job. If your budget allows for it, you might be better off investing in a real charger. However, this project was an enjoyable and successful venture that proved to work well.
