HDZero Rear-Mount Battery Case with SD Card Reader includes 2 x Samsung 21700 5000mAh batteries

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).
