HDZero HDZ2170 Rear-Mount Battery Case
Global version: batteries are not included. Add two compatible 21700 lithium-ion cells to use this rear-mount power case with suitable FPV goggles. The HDZ2170 combines USB-C charging, internal cell balancing and a USB 3.0 microSD reader in one housing.
Mount the case at the back of a compatible goggle strap to help balance the headset. After flying, use the integrated card reader to transfer DVR files without packing a separate reader.

Check Compatibility Before Connecting
Confirm your goggles accept the full listed 6.0–8.4V range, have matching connector polarity and use a compatible 5.5 × 2.1mm input. Connector dimensions alone do not establish compatibility. The source identifies HDZero Goggle and BoxPro; check the exact model's requirements before use.
Use cells approved for this case by the manufacturer. Confirm cell length, terminal style, protection-board fit and current capability rather than assuming every protected or unprotected 21700 cell will fit. Use a suitable USB-C power supply and cable; a data-capable cable is required for file transfer. Reader speed depends on the card, cable and computer.
Perfect For
FPV pilots who want a rear-mounted goggle power solution with removable cells and an integrated reader for transferring flight recordings.

Cell Handling and Charging Safety
Follow the manufacturer's cell-selection, installation and charging instructions. Install cells with the correct polarity, and never rely on protection circuitry as a substitute for checking orientation. Do not use cells with damaged wraps, dents, leaks or overheating. Keep loose cells away from metal objects, supervise charging and stop use if the case or cells behave abnormally.
