Compatible replacement for Insta360 X3

This four-pack of Kastar lithium-ion cells is built specifically for the Insta360 X3 action camera. Each cell delivers 1800 mAh at 3.85 V for a total of 6.9 Wh. The pack targets creators who need multiple spares for extended shoots with the 72 MP waterproof 5.7K 360° VR AI helmet camera.

Capacity and headroom

A single 6.9 Wh cell powers the X3 through typical recording sessions, and four cells provide enough reserve for full-day capture without wall charging. The chemistry tops out at the stated capacity, so back-to-back 360° clips at maximum resolution will eventually drain each pack and require a swap or recharge.

Physical fit constraint

The X3 battery bay accepts the shorter 2.17" x 0.51" x 1.65" form factor; the longer 2.36" x 0.55" x 1.57" ONE X2 cell will not seat correctly. Built-in protection meets UL1642 and CE standards, guarding against over-charge, over-discharge, over-voltage, over-current and over-heating during use.

Questions about this item

Will these batteries fit the Insta360 ONE X2 I already own?

No. The ONE X2 uses a longer cell measuring 2.36" X 0.55" X 1.57", while these packs are built for the shorter 2.17" X 0.51" X 1.65" form factor of the X3.

How can I verify each cell is healthy after the first charge?

Insert a battery into the X3, power on and confirm the camera reports 3.85 V and 1800 mAh; the built-in protection circuit prevents over-charge, over-discharge and over-heating during that initial cycle.

Does the 4-pack include a charger or only the four batteries?

Only the four Li-Ion cells are supplied; a compatible charger for the Insta360 X3 must be purchased separately.
