Eken H9R Action Camera Power Bank

thingiverse

Extreme Power Battery Case for Eken (SJCam, ...) Action Cameras. This robust case replaces the scuba housing back door and can hold up to two high-capacity 18650 Li-Ion cells. These cells provide a combined power of up to 7000mAh when connected in parallel, effectively tripling the camera's operating time. The cells are securely connected in parallel, generating an internal battery voltage of 3.7V-4.2V. The wires are carefully glued onto the Battery Adapter threads, forming U-shape connectors at the upper end. Refer to the accompanying image and original battery for a clear understanding. Note that when the case is closed, it may obstruct visibility of the back screen. However, users can still power up the camera using the front button and activate WiFi by pressing the lower side button. The remote app can then be used to control the camera's functions. Please note that even with added shielding, the printed unit itself may not be fully waterproof.
