DJI Pocket 2 Replacement Battery 3.7V 300mAh BHX211-320

DJI Pocket 2 — 3.7V Li-Polymer Replacement Battery (BHX211-320)

This 3.7V, 300mAh Li-Polymer cell replaces the internal battery in the DJI Pocket 2 handheld gimbal camera. It powers both the three-axis motorized stabilization system and the internal video processing electronics. Capacity figure is taken from product data — 300mAh at 3.7V, 1.11Wh.

• Pocket 2 platform fit: The Pocket 2 uses a compact integrated body where the gimbal motors, sensor, and processor all share a single small cell on one voltage rail. BHX211-320 matches that rail at 3.7V nominal, and the cell dimensions — 26.70 x 20.80 x 5.40mm — fit the internal bay without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Pocket 2 body. The BMS accepted the cell, gimbal calibration completed normally on startup, and no over-temperature flags tripped during sustained video recording.
• First-cycle BMS initialisation: Charge this cell fully through the Pocket 2 body using the OEM USB-C cable before your first recording session. The Pocket 2's onboard BMS maps battery-remaining percentage to the cell's discharge curve during that first cycle — skipping it causes erratic percentage readings from the start.

Gimbal motor draw spiking on stabilisation events

The Pocket 2 pulls current from the battery in short bursts whenever the three-axis gimbal corrects for movement. On a small 300mAh cell, those correction spikes can cause momentary voltage sag if the cell is aged or poorly matched to the body. A fresh BHX211-320 cell with low internal resistance handles those correction bursts without dropping below the BMS cutoff threshold. If you see the gimbal stuttering or the device resetting mid-movement, check that the replacement cell is fully charged — sag events happen sooner at partial state of charge.

Battery percentage jumping or freezing on the Pocket 2 display

This happens when the Pocket 2's BMS hasn't mapped its voltage thresholds to the new cell's discharge curve. The indicator is calibrated during the first full charge-discharge cycle inside the camera body — if that cycle was skipped, the display pulls percentage from a mismatched reference. The fix is straightforward: drain the cell until the Pocket 2 shuts itself off, then charge it fully via the body before using it again. After one complete cycle, the percentage readout stabilises and tracks correctly.
