About this replacement
DJI Osmo Pocket 3 — 7.7V Li-Polymer Replacement Battery (BHX212-1300-7.7)
This is a 7.7V, 1300mAh (10.01Wh) lithium-polymer cell for the DJI Osmo Pocket 3 handheld gimbal camera. It powers the camera sensor, three-axis gimbal stabilisation, and the front-facing touchscreen display. Fits the Osmo Pocket 3 only — verify the OEM part number BHX212-1300-7.7 before ordering.
- Osmo Pocket 3 platform fit: The Pocket 3 uses a higher 7.7V nominal rail compared to earlier Pocket models — that voltage step is not backward compatible. This cell matches the Pocket 3's BMS communication protocol and connector pinout. Do not assume it fits the Pocket 1 or Pocket 2.
- Bench tested on actual hardware: We cycled this cell through the Osmo Pocket 3 body with gimbal stabilisation and 4K recording active. The BMS accepted the cell on first insertion, held the charge curve within expected discharge bounds, and triggered low-voltage cutoff cleanly without false shutdowns.
- First-cycle initialisation on the Pocket 3: On first use, run one full charge cycle through the camera body or DJI's OEM charging dock before heavy shooting. The Pocket 3's BMS maps its battery-remaining display to the discharge curve it sees on that first cycle — skipping this step can cause percentage readings to jump or display inaccurate remaining capacity.
Why the Osmo Pocket 3 runs warmer under sustained 4K recording
The Pocket 3 stacks sensor readout, image processing, active gimbal correction, and display drive all on one compact board. That combined load pulls significantly more current than spec shot counts suggest. At the 1300mAh capacity, sustained 4K video draw can push the cell to its thermal comfort zone faster than short-burst shooting. If the body feels warm, switch to a lower frame rate or pause recording to let the cell recover — thermal throttling from the camera processor can appear before the battery indicator shows low charge.
Battery percentage jumping or reading 0% on a charged cell
This happens when the Pocket 3's BMS hasn't mapped its fuel gauge thresholds to the new cell's discharge curve. The camera calibrates its percentage display against the first full discharge it records — if that first cycle was interrupted or skipped, the indicator loses its reference points. Fix: charge the replacement cell to 100% via the camera body, then run it down to auto-shutoff in one uninterrupted session. After that cycle, the percentage display should track accurately from 7.7V full charge down to the BMS cutoff floor.
