This is a quick video tutorial demonstrating how to add the BLE660C module to a Leopold FC660C.
CORRECTION AT 9:00: The battery will charge when USB is plugged in, regardless whether the button is on or off.
I believe the module's original seller is on Taobao, but it looks like there are some resellers shipping from China on eBay. If you're outside of China, ordering from Taobao may be difficult, I think eBay is generally simpler despite the mark-up.
Module on Taobao: world.taobao.com/item/5902365...
Module on eBay: www.ebay.com/sch/i.html?_nkw=...
Battery: www.amazon.com/gp/product/B07...
The battery I used was 503365 but the ideal size is 493998.
