HDZero Rear-Mount Battery Case with SD Card Reader

HDZero Battery Case is a case for powering FPV goggles with a standard DC connector 5.5 × 2.1 mm. The case is supplied without batteries and is designed for two 21700 size Li-ion cells. It allows charging cells via USB-C without the need for an external charger and provides automatic cell balancing for safe and stable operation.

The case is equipped with reverse polarity protection. If the cells are inserted incorrectly, the output is automatically deactivated, protecting both the goggles and the connected device. Rear strap mounts allow the case to be attached to the back of the head strap, improving the balance of the goggles, comfort during wear, and proper antenna orientation.

The case includes an integrated high-speed MicroSD card reader, which allows for quick downloading of DVR recordings during charging. Since the card remains stored in the case, there is no risk of forgetting it in the computer or in the field.

The HDZero Battery Case is compatible with most FPV goggles on the market, including HDZero, Walksnail, Skyzone, Orqa, and other models using the 5.5 × 2.1 mm power connector.
