HDZero Battery Case
The HDZero Battery Case is the ideal power solution for HDZero Goggle, BoxPro Goggle, and any FPV headset that uses a standard 5.5 x 2.1 mm barrel jack. Built around two premium Samsung 21700 cells, this smart 2S pack delivers long runtime, USB-C charging, automatic cell balancing, a built-in high speed Micro SD card reader, and integrated safety protections.
Mount it to the rear of the goggle head strap using the integrated clips to counterbalance the weight of your goggles. This improves comfort and maintains better antenna orientation during flight.
Key Features
Long Runtime Power 2S1P 5000mAh pack built from high quality Samsung 21700 cells. Provides about 3 hours of runtime on HDZero Goggle or BoxPro Goggle.
USB-C Charging and Built-In Balancer Charge with any USB-C cable. No special LiPo charger required. The pack continuously balances cells for long term safety and performance.
Integrated High Speed Micro SD Card Reader Built-in USB3.0 Micro SD card reader (>90 MB/sec). Offload DVR footage easily while the pack charges. The SD card travels with the battery so you will not forget it in your PC.
Reverse Polarity Protection If cells are installed backward, the battery case automatically disables output to protect your goggles and equipment.
Comfortable Rear Mount Design Integrated head-strap clips allow the battery to mount on the back of the goggles. This balances the weight, reduces neck strain, and improves antenna orientation.
Reliable Power Delivery More consistent output than many USB-C power banks. Reports correct voltage to the goggles for accurate low voltage alarms.
Universal Compatibility Works with any FPV goggle using a5.5 x 2.1 mmDC barrel input (HDZero, Walksnail, Skyzone, Orqa, and others).
