Two-pack replacement for Insta360 ONE X2

This Kastar IS360X2B kit supplies two lithium-ion cells rated at 1700 mAh and 3.85 V, together delivering 6.5 Wh of energy. Each unit includes built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The cells meet UL1642 and CE safety standards. They are designed as direct replacements for the original Insta360 ONE X2 battery.

Suits owners needing spare power for long shoots

Videographers who carry an Insta360 ONE X2 and want extended recording time will benefit from the extra capacity. The pack is not compatible with the Insta360 X3 or ONE X3 models because those cameras require a shorter cell measuring 2.17 by 0.51 by 1.65 inches. Buyers using newer Insta360 bodies should look for a different battery.

Steady output during continuous capture

The protection circuit maintains stable voltage throughout a full discharge cycle, preventing sudden shutdowns when the camera writes large 5.7K files. Heat buildup is managed by the over-temperature guard, so performance remains consistent during prolonged 360-degree sessions. Cycle life is extended by the same safeguards that limit stress on the lithium-ion chemistry.

Questions about this item

Which Insta360 camera model must I own for these two batteries to fit and power it?

They are built for the Insta360 ONE X2 action camera; the supplier notes they will not fit the ONE X3 because that model uses a shorter 2.17 x 0.51 x 1.65 inch cell.

If I keep my original Insta360 charger, will it charge these 1700 mAh 3.85 V cells correctly?

Yes, the pack is listed as a direct replacement for the CINOSBT/C battery, so the factory charger that came with your ONE X2 will charge them normally.

How can I verify the batteries are delivering their rated 6.5 Wh capacity after the first few charge cycles?

Record a typical 5.7 K 360 session until the camera shuts down, then check the runtime against the 1700 mAh rating; consistent runtimes near the spec confirm the cells are performing as intended.
