Overcurrent Protection 4. Drop Protection 5. Short Circuit Protection 6. Temperature Protection 7. Balanced Protection 8. Electrostatic Protection 9. Dust Protection 10. Moisture Protection

Compatibility with Scooter Battery Packs Bisida's BMS models, including 7S, 10S, and 13S, are suitable for supporting scooter battery packs with standard voltages of 24V, 36V, and 48V. Additionally, these BMS solutions can be utilized in solar energy storage systems, UPS energy storage equipment, and other battery pack applications.

Support for Various Voltage Configurations Bisida's Lifepo4 BMS can accommodate a wide range of voltage configurations, including 12S (4S), 24V (8S), and 51.2V (16S), making it suitable for diverse energy storage devices, solar cells, UPS batteries, and more.

Multi-Function Protection Bisida's BMS offers a comprehensive range of protection features, safeguarding against overcharge, overdischarge, overcurrent, short-circuits, temperature fluctuations, and voltage imbalances (passive balancing). These advanced protection functions ensure the safety and reliability of the energy storage systems.

Operating Temperature Range Bisida's BMS supports the charging and discharging of (3.7V) lithium-ion batteries within a temperature range of -20°C to 70°C, providing low-temperature and high-temperature protection. The specific parameter details may vary based on the voltage and current requirements, and users are advised to consult with the seller to confirm the accurate data.

Pre-Installation Preparation Before installing the BMS protection board, it is crucial to ensure that the voltage, capacity, and internal resistance of the battery pack are properly matched. The voltage difference between individual battery cells should not exceed 0.05V, the internal resistance difference should be no more than 5MΩ, and the capacity difference should be less than 30mAh. Failure to meet these requirements may result in the inability to charge the battery pack.

Wiring Method The wiring connections for Bisida's BMS are as follows: B- (battery pack negative), C- (charging negative), and P- (output negative). All positive electrodes are connected to the total positive pole from the battery pack.

High-Quality Components Bisida's BMS utilizes top-quality (A-level) protective integrated circuit (IC) components sourced from industry-leading solutions. The BMS is manufactured using high-quality MOSFETs and ICs, ensuring reliable performance. Bisida also offers OEM/ODM customization services to accommodate specific customer requirements.
