DaVinci IQ3 replacement battery

DaVinci IQ3 21700 Battery

Device-specific 21700 reference: DaVinci explicitly describes this 4000-mAh battery as a replacement battery for the IQ3.

The manufacturer binds the cell format and replacement identity directly to one named device.

The product page names only the IQ3 and provides no approval for other 21700 devices or for an arbitrary same-format cell.

Do not convert the product specification into a general electrical safety claim; retain the permanent compatibility notice and the IQ3-only scope.

Approved evidence is limited to replacement use in the DaVinci IQ3 and does not establish suitability for any other 21700 device.
