Rechargeable battery BOBOVR B100 for S3 PRO / E3 PRO, 2000 mAh

The BOBOVR B100 battery pack is a high-capacity rechargeable power source designed for use with BOBOVR S3 PRO and E3 PRO VR headsets. With a 10,000 mAh lithium-ion cell configuration (nominal capacity 4800 mAh, nominal energy 35.04 Wh) and a magnetic mounting system, the B100 extends headset runtime while maintaining compatibility and a compact form factor.

Advantages

The B100 increases operating time by approximately 135% compared with the original cells, while keeping the same external dimensions and adding only moderate additional weight (184 g). It uses high-performance 3.65 V cells with an integrated Texas Instruments BMS for accurate charge monitoring and four front LEDs to indicate the current charge level. Fast charging up to 20 W is supported (USB-C input 5.0 V 3 A), and multiple safety features and temperature sensors protect against overheating, overcharge and short circuits.

Suitable for

• Extending playtime on BOBOVR S3 PRO and E3 PRO headsets
• Replacing worn or depleted batteries in compatible headsets
• Keeping as a spare battery for uninterrupted VR sessions

Monitor the four LED indicators on the battery housing to check charge level before and during use.

Recommendations

Use only the supplied charging cable or a compatible USB-C charger rated for the battery input (5 V, up to 3 A). If you own M1, M2 Plus, M3 Pro or M3 Mini series headsets, purchase the B100U upgrade kit for compatibility. Store the battery in a cool, dry place and avoid exposing it to high temperatures; follow the user manual for safe charging and disposal.
