Brand new B100 battery system: Compared with B2, while the volume remains unchanged, the cell capacity is increased from 5200mah to 10000mah(Battery cell capacity), 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; | 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; | Adopting a high voltage scheme to improve the efficiency of electricity conversion and bring higher power output and lower heat generation. | Tip: B100 is only compatible with the new S3 Pro Strap and is not compatible with BOBOVR M2/M3 series headbands. Please do not buy by mistake.(The battery cell is 10000mah/3.65V or 5000mah/7.3V. In order to prolong the life, the system has stored 4% of the power. The actual available capacity is 4800mah*7.3V=35.04Wh)
