BOBOVR B2 - Battery Pack

Extend your VR sessions with the BOBOVR B2 battery

Designed to fit BOBOVR head straps, the B2 battery provides a welcome boost in battery life for Meta Quest and PICO headset users. With its 5200 mAh capacity, it can nearly double available playtime, while maintaining a compact, lightweight form factor designed not to weigh down the back of your head.

Key features

• 5200 mAh capacity (3.7 V) for extended battery life
• Weighs just 140 g, for improved front/back balance
• Magnetic attachment and hot-swap: seamless replacement without interruption
• Charge/discharge power of up to 15 W
• Charges to 80% in approximately 2 hours, full charge in approximately 3 hours
• 4 LED charge level indicators and activity halo light
• Built-in redundant electronic protections

Why choose the BOBOVR B2 battery?

The ability to hot-swap the battery with a simple magnetic connection makes a real difference in practice: no more need to interrupt a game or an immersive work session to recharge the headset. By combining multiple B2 units, battery life becomes virtually unlimited. Its lightweight design also reduces neck fatigue during extended sessions — an often overlooked but crucial factor for everyday comfort.

Compatibility

The B2 battery fits BOBOVR straps from the M1, M2, and M3 series, as well as the P4S strap. However, it is not compatible with the S3 Pro strap, which uses a different battery standard.
