HDZero Rear-Mount Battery Case with SD Card Reader

HDZero Battery Case is a universal power solution for FPV goggles with a standard 5.5 x 2.1 mm DC connector. The international version comes without batteries, so you can use any quality 21700 Li-ion batteries. When installed with two batteries, the Battery Case ensures long runtime, supports USB-C charging, automatic battery balancing and has an integrated high-speed MicroSD card reader for transferring DVR recordings. The attachment at the end of the goggle strap improves weight balance and comfort of use.

Features:

• Use 21700 Li-ion batteries from any trusted manufacturer – you can choose the capacity and manufacturer that suits you best. Compatible with both protected and unprotected 21700 batteries;
• Charge batteries using any USB-C cable – no additional LiPo charger required. Integrated electronics automatically balance battery cells, ensuring safer and longer-lasting operation;
• The built-in USB 3.0 MicroSD card reader allows you to quickly transfer DVR recordings while the batteries are charging. Since the memory card remains in the Battery Case, there is less chance of forgetting it in the computer;
• If the batteries are inserted incorrectly, the Battery Case automatically turns off the power output and protects the glasses and other connected devices;
• Special holders allow you to attach the Battery Case to the rear part of the glasses strap, thus improving weight balance, reducing pressure at the front and ensuring more comfortable use and optimal antenna position;
• Provides more stable power than most USB-C external batteries and accurately transmits voltage information to the glasses, so low-voltage warnings are more accurate;
• Works with all FPV goggles that use a 5.5 × 2.1 mm DC power connector, including HDZero, Walksnail, Skyzone, Orqa and other models.
