Battery Strap for Quest 3 and 3S

The BoboVR S3 Pro replaces the standard head strap on Meta Quest 3 and 3S headsets. It integrates a 10000mAh battery pack that charges at 20W and uses a hot-swap design to separate the discharge module from the cell. This architecture cuts pack heat and raises discharge efficiency by 6% over the previous B2 system while adding low-battery alerts and precise level readouts.

Active Cooling and Weight Balance

A built-in forehead fan runs at 100 adjustable speed levels using silent technology to keep the face cool during extended sessions. The new B100 battery nearly doubles capacity from 5200mAh to 10000mAh — a 92% increase — while adding only 28% more weight. The flatter rear profile and height-adjustable overhead bracket improve comfort when leaning back or lying down.

Hot-Swap Battery Extends Sessions

The modular battery design lets users swap a fresh pack in seconds without removing the headset, effectively removing the play-time limit imposed by the internal cell. Faster 20W charging reduces downtime between swaps. The efficiency gain means more usable energy per charge cycle, and the audible low-battery warning prevents unexpected shutdowns during use.

Questions about this item

How do I attach the strap to my Quest 3 or 3S, and what step do people miss?

Slide the headset into the front mount, then fasten the rear dial and overhead bracket; the step often missed is setting the bracket height before tightening the dial so the weight sits on the crown, not the face.

What part will need replacement first, and how do I swap it?

The B100 10000mAh battery pack is the only consumable; it releases with the power-swap latch so you can snap in a fresh pack without removing the headset.

What limits comfort during long sessions — fan noise or battery heat?

The 100-level silent forehead fan keeps airflow steady, while the separated discharge module cuts pack heat by 6% versus the old design, so neither noise nor warmth becomes the limiting factor.
