Sonoff Motion Sensor Battery Box for Lithium battery.

I wanted to stop using single use button cell batteries for my sensor so i modified the box to hold a single use vape rechargeable battery and a charging module so i can charge the battery through usb-c.

The battery is secured in place using a zip tie, and you'll have to add a little hot glue at the back of the TP4056 module to secure it in place.

• TP4056 module rails and usb-c hole.
• Battery holder
