Overview:
The HDZero Rear-Mount Battery Case with SD Card Reader is a smart external power solution designed to enhance comfort, convenience and capability for FPV goggle users. It allows the use of standard 21700 Li-ion cells to deliver stable, long-lasting power while integrating USB-C charging, continuous cell balancing and an ultra-fast Micro SD card reader into a single compact housing.
Its rear-strap mounting clips position the pack at the back of the head strap, improving balance and comfort during extended flying sessions. Compatible with a wide range of FPV headsets that use a 5.5×2.1mm DC barrel input, this unit is ideal for pilots who want a clean, integrated power and DVR file-offload solution.
Features:
- Accepts two standard 21700 Li-ion cells of your choice.
- USB-C charging system with built-in cell balancer allows convenient charging without a separate LiPo charger.
- High-speed Micro SD card reader (USB3.0, >90 MB/s) right in the battery housing lets you offload DVR footage quickly.
- Rear-mount head strap clips shift battery mass behind the head, reducing forward tilt and increasing comfort.
- Reverse polarity protection helps prevent damage if cells are inserted incorrectly.
- Provides more stable and goggle-friendly power delivery than many USB power banks, including correct voltage reporting for accurate goggle low-voltage alarms.
