Extreme capacity battery box for the Eken (SJCam, ...) Action camera. The box will replaced the scuba housing back door and can carry up to two 18650 Li-Ion cells. They can provide up to 7000mAh (connected to parallel) power, meaning 7x operation time.
The cells are connected _parallel_ to give voltage 3.7V-4.2V (as internal battery).
The wires are glued to the Battery Adapter treads. Make U-shape connectors to the upper end. See the picture and the original battery.
