Note: B100 is Only Compatible with S3 Series.  The B100 battery requires the B100U upgrade kit to be compatible with the M1/M2 plus series and M3Pro/M3mini. Please check the B100U upgrade kit. Brand new B100 battery system: Compared with B2, while the volume remains unchanged, the cell capacity is increased from 5200mah to 10000mah, the battery capacity is increased by 92%, and the weight is only increased by 28%. Thanks to the higher output efficiency, the available capacity is B2 2 times; Using high-precision BMS chips from Texas Instruments, it can accurately calculate the available battery power and transmit it to the load end to provide 1-100% battery display;（The battery pack itself comes with 4 LEDs for quick battery level checking.） Built in multiple temperature sensors and protection switches, real-time detection of temperature at different internal positions, significantly reducing working temperature compared to the previous generation of products; Enhanced services: If you are willing, we offer an additional fast charging dock BD3, supporting 30W fast charging power. It can charge up to 80% in 1 hour, providing 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). The B100 consists of 2 independent batteries connected in series, 5000mah/7.3V or equivalent to 10000mah/3.65V,BOBOVR is committed to product innovation and high-quality manufacturing. We provide up to 18 months of after-sales guarantee service.
