BOBOVR B100U Upgrade Kit for M1/M2/M3 Strap VR Accessories Compitable with Quest 3 10000mAh Hot-Swap Battery 20W Fast Charging The B100U upgrade kit supports the BOBOVR M1/M2/M3 series , allowing for a complete upgrade of the original B2 battery system, providing higher charging power and double the available capacity. Still using BOBOVR's innovative battery swap design, the new battery architecture separates the discharge module from the battery pack to reduce heat generation. The battery pack adopts a high-voltage scheme (4.2v - 8.4v), increasing the discharge efficiency by 6% compared to the old model, and adding low battery alerts and precise battery level monitoring. - New B100 battery system: Compared to the B2, the capacity has increased from 5200mAh to 10000mAh without changing the volume, a 92% increase in battery capacity with only a 28% increase in weight. Due to higher output efficiency, the available capacity is twice that of the B2. - Enhanced services: If you wish, we offer an additional fast charging dock BD3, supporting 30W fast charging power, which can charge up to 80% in 1 hour for 3 hours of usage (the slow charging provided by the battery pack itself takes 4 hours, requiring more charging time due to nearly doubling the capacity compared to the B2). - BOBOVR is committed to product innovation and high-quality manufacturing, and we provide up to 18 months of after-sales guarantee service.
