DJI Osmo HB01 11.1V Compatible Battery 1100mAh Li-Polymer

DJI Osmo Handheld 4K Camera / Zenmuse X3 — 11.1V Li-Polymer Replacement Battery (HB01)

This is an 11.1V, 1100mAh Li-Polymer replacement battery for the DJI Osmo handheld gimbal camera and Zenmuse X3/X5 camera heads. It uses OEM part number HB01 (also referenced as HB01-522365). It fits the Osmo's battery compartment directly and powers both the three-axis stabilisation motors and 4K camera system simultaneously.

• Osmo and Zenmuse X3/X5 compatibility: These models share the HB01 battery format because they run the same 11.1V power rail and use the same physical connector and BMS communication protocol. The Osmo handle and Zenmuse camera heads both draw from this cell during active gimbal operation.
• Bench tested on actual hardware: We ran this cell under combined stabilisation motor and camera load. The BMS held charge delivery steady across the full draw profile, with cutoff triggering correctly at the low-voltage threshold without premature shutdown.
• First charge on the Osmo body: Insert the cell and charge it fully inside the Osmo handle using the OEM charger before your first shoot. The Osmo's BMS maps its battery-remaining display to the cell's discharge curve during this first charge cycle — skipping it can cause inaccurate percentage readings throughout the battery's life.

Why the Osmo cuts power mid-shot during active gimbal movement

The Osmo pulls current from two sources simultaneously: the camera sensor and processor, and the three gimbal motors correcting for movement. During fast panning or heavy correction events, instantaneous current draw spikes well above the steady-state figure. If the cell's internal resistance is elevated — common in aged or deeply discharged batteries — voltage sags under that spike and the BMS trips the output to protect the cell. This is not a charger fault or a firmware issue. The fix is a fresh cell with low internal resistance, which absorbs the motor-start surge without dropping below the BMS cutoff threshold.

Osmo battery percentage jumping erratically after installing a replacement cell

The Osmo maps its fuel gauge display to a voltage-to-capacity curve calibrated during the first full charge cycle. A new cell that has not been charged from within the Osmo body can present a discharge curve the BMS hasn't mapped yet, causing the percentage indicator to skip or read inconsistently. This is not a faulty battery. Charge the replacement cell fully via the Osmo handle — not an external charger — and run it down to automatic shutoff once. After that full cycle the BMS recalibrates its threshold mapping and the percentage display stabilises. Expect accurate readings from the second charge onward.
