Compatible Replacement

This four-pack of lithium-ion batteries replaces the Insta360 ONE X2 power cell. Each unit delivers 1700mAh at 3.85V for 6.5Wh capacity. They are not compatible with the Insta360 ONE X3 or X3 models due to different dimensions. Photographers needing a direct swap for the original battery will find these suitable.

Build Integration

The pack supplies four cells so you can keep spares charged and swap them without downtime. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating. No extra hardware is required beyond the camera and its standard charger. Buyers who want more storage or a second card slot will not gain that from this product.

Sustained Operation

Cells meet UL1642 and CE safety standards for reliable output during long shoots. The protection circuitry maintains stable voltage under continuous discharge rather than only in short bursts. Cycle life benefits from the quality build and integrated safeguards. Users who need waterproof housings or higher-capacity alternatives must look elsewhere.
