Insta360 One X5 Replacement Battery 3.89V 2550mAh CINSBAHA

Insta360 One X5 — 3.89V Li-ion Replacement Battery (CINSBAHA)

This is a 3.89V, 2550mAh (9.92Wh) Li-ion replacement battery for the Insta360 One X5 360-degree action camera. It matches the OEM part number CINSBAHA and fits the One X5 body directly. Voltage, connector, and cell dimensions align with the original specification.

• One X5 platform fit: The One X5 uses a dedicated battery format with a proprietary contact layout and BMS handshake tied to the CINSBAHA cell spec. Swapping to a cell outside that voltage window causes the camera to reject the battery at boot — this cell stays within tolerance.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the One X5 body. The BMS accepted the cell without error flags, and the camera's battery indicator tracked consistently through the discharge curve from full to cutoff.
• First-install charge cycle on the One X5: Run the first full charge via the camera body or OEM USB-C charger before heavy shooting. The One X5's BMS calibrates its battery-remaining display against an internal charge profile — skipping this step can cause the percentage readout to behave erratically from the start.

Why the One X5 drains faster during 360 video than the shot count suggests

The One X5 runs dual lenses, dual image sensors, and a stitching processor simultaneously during video capture. That combined draw is significantly higher than what the camera's rated shot count implies, which is typically calculated under still-photo conditions. Add FlowState stabilisation and active cooling cycles, and sustained video draw can be two to three times the still-photo baseline. Capacity figures like 2550mAh reflect total stored energy — actual recording duration depends on which features are active.

Battery percentage jumping or resetting to 1% mid-session

This happens when the camera's fuel gauge hasn't mapped its discharge thresholds to the new cell's voltage curve. The One X5 BMS compares real-time cell voltage against a stored reference table — a fresh cell with a slightly different curve causes the displayed percentage to snap between values instead of stepping down smoothly. Running two or three full charge-discharge cycles through the camera body forces the BMS to re-learn the curve. After conditioning, the percentage display stabilises and tracks accurately down to the low-voltage cutoff near 3.0V per cell.
