From the project
WIP + POC usb Charging for Emisar D4v2 Flashlight
A work-in-progress proof of concept for adding built-in USB-C charging to the Emisar D4v2 flashlight, using a pogo-pin connector in place of removing the cell to charge it externally.
The charger PCB is a disc that sits sandwiched between the flashlight body tube and the head, in the same joint where they normally screw together. A spring contact on the board presses against the cell's positive terminal, while the pogo-pin connector protrudes to the side to bring in USB-C power through the body wall.
