Hộp Pin Sonoff Cảm Biến Chuyển Động Cho Pin Lithium

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.
