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 a 5.5 x 2.1 mm DC barrel input (HDZero, Walksnail, Skyzone, Orqa, and others).

Does a great job at redistributing the weight so you feel less torque on your head/neck; pads are nice and soft as well. It doesn't slide around the headband, it's going to stay right where you put it. Charging the batteries via a standard USB-C is amazing, as I don't have to figure out which battery charger to get (and power source). LEDs on the case show the charge level, allowing you to see with a glance how charged you are. Haven't made use of the micro SD-card slot myself yet, but I appreciate the option.
Works perfectly -- I can't imagine using my goggles without this, tbh. Also glad to see they're working on a (free) updated part to add some cable strain relief, too!
The item bis.
Battery pack itself works fine. It has a defect with the power cable coming out of the pack that causes it to not work after a while. While the company is proactive with providing 3D prints that help prevent this issue, and they say they are coming out with a permanent solution, I’m really hoping that they provide the solution for free without shipping costs. I understand that no product is perfect, but at this price point I shouldn’t pay a cent more due to an under engineered product that didn’t go through enough testing. Otherwise it’s 5 stars.
Great battery. Feels good while wearing it and the card reader is an awesome feature. I wish they would fit it the goggles case while still on the strap. Other than that it is great.
