Two-Pack Replacement Battery for Insta360 X3

This pack supplies two Kastar lithium-ion cells rated at 1800 mAh and 3.85 V. Each cell stores 6.9 Wh of energy for the Insta360 X3 72MP waterproof 5.7K 360° VR AI action helmet camera. The batteries are new and built to the same physical profile as the original power source.

Check camera model and battery bay dimensions

The cells measure 2.17" x .51" x 1.65" and are confirmed for the Insta360 X3 only. They will not fit the Insta360 ONE X2, which uses a longer 2.36" x .55" x 1.57" battery. Verify the exact model printed on your camera body to avoid a mismatch.

Sustained recording protected by multi-circuit

Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating during long capture sessions. The cells meet UL1642 and CE safety standards, so temperature and voltage remain controlled when the camera runs continuously at high bit-rates.

Questions about this item

Does the 2-pack include a charger or just the two 1800 mAh batteries?

The pack contains two Li-ion batteries rated at 3.85 V and 6.9 Wh each. A charger is not included and must be purchased separately.

The listing mentions both Insta360 X3 and ONE X2 — which one fits the 2.17" × 0.51" × 1.65" battery?

The shorter 2.17" × 0.51" × 1.65" cell is built for the Insta360 X3. The longer 2.36" × 0.55" × 1.57" cell used in the ONE X2 will not fit.

With the 6.9 Wh rating, how long can I record 5.7K 360° video on the X3?

The 1800 mAh / 6.9 Wh pack powers the X3 for its full rated capture session at 5.7K 360°; actual minutes vary with temperature, stabilisation and screen use.
