BMS 7S-17S 120A 3,2V Smart Bluetooth, Jiabaida

Smart BMS 7S-17S LiFePO4 120A by Jiabaida

BMS is a powerful and reliable battery management system. It ensures optimal performance, safety and long life of LiFePO4 batteries. This system uses an O2 chip architecture for data acquisition and an MCU from HDSC, ensuring accurate and reliable battery management. It allows for flexible adjustment of protection parameters, making it customizable for different customer needs.

✅ Monitors voltage: constantly checking the voltage of each cell to ensure that none overcharges or over-discharges and damages the battery

✅ Controls charging and discharging: regulate the current during charging and discharging to avoid overcharging the battery

✅ Balances cells: balances differences in cell voltage for optimum performance and battery life

✅ Transmits information: allows communication with a computer, tablet or mobile phone to monitor status and adjust settings

Suitable applications

• Backup Power Supplies (UPS): the BMS is ideal for UPS systems that require reliable and safe power during a power outage.
• Solar Systems: the BMS is used in solar systems to store and manage the energy from photovoltaic panels.
• Electric vehicles: the system is suitable for electric bikes, scooters and small trucks that use LiFePO4 batteries.
• Portable power stations: the BMS is used in portable power stations for camping, outdoor activities and emergency situations.
