BOBOVR B100 Battery – 10000mAh Spare for S3 Pro Strap

The BOBOVR B100 battery is the 10000mAh replacement cell for the BOBOVR S3 Pro battery head strap. Keep one charged as a spare and hot-swap it magnetically when the fitted battery runs low, so a long VR session never has to stop.

What the B100 battery is for

A spare cell for the S3 Pro strap

The BOBOVR S3 Pro head strap ships with one B100 cell. This is a second one: charge it on the side, then swap it in without taking off the headset. Two B100 batteries in rotation give you effectively unlimited playtime.

10000mAh capacity

Each B100 holds 10000mAh, the full-size battery for the S3 Pro. It powers the Meta Quest 3S or Quest 3 through the strap's pass-through while you play and recharges over USB-C between sessions.

Magnetic hot-swap

The B100 clicks onto the back of the S3 Pro strap with a magnetic mount and releases the same way, so changing batteries takes seconds and no tools.
