Safie Pocket 2 Body Camera Replacement Battery HDS134345 3.8V

Safie Pocket 2 — 3.8V Li-Polymer Replacement Battery (HDS134345)

This 3.8V, 3400mAh Li-Polymer battery replaces part number HDS134345 in the Safie Pocket 2 body camera. It restores full recording capacity when the original cell has degraded. Dimensions are 43.30 × 42.40 × 14.00mm — confirm fitment against your existing pack before installing.

• Pocket 2 compatibility: The Safie Pocket 2 uses a flat Li-Polymer cell at 3.8V nominal. The BMS handshake on this camera validates cell voltage on power-up — a cell outside that range will be refused before the camera reaches ready state.
• Bench tested on actual hardware: We ran this cell under combined 1080p video encode and active Wi-Fi upload — the sustained draw that stresses body camera BMS protection most. The cell held voltage without tripping protection cutoff across the full discharge cycle.
• Post-swap power-up check: After fitting this battery, power on the camera and wait for the ready indicator before starting a shift. The Pocket 2 runs a self-check on every boot — if the status light does not reach ready, remove the battery for 10 seconds and reseat it to re-trigger the handshake.

Why the Pocket 2 BMS trips during simultaneous recording and Wi-Fi upload

The Pocket 2 draws from two high-load sources at once when it records and uploads simultaneously — the video encode pipeline and the wireless radio. A degraded or undersized cell sees that combined draw as an overcurrent event, and the BMS cuts output to protect the cell. This replacement cell is rated to handle the sustained draw of both loads running together. If trips continue after swap, check whether auto-upload is scheduled during active recording in the camera's app settings.

Battery indicator reads low after a short recording session on a new cell

A new Li-Polymer cell sometimes reports inaccurate state-of-charge for the first few cycles because the camera's fuel gauge is still calibrated to the old cell's discharge curve. The indicator will read low even when the cell has significant charge remaining. Run the battery through two full discharge-and-charge cycles to let the gauge recalibrate. After that, the indicator should track correctly against the 3400mAh capacity of this cell.
