20S BMS 72V Lithium Ion Protection Board with Balance Wire and NTC, Common Port, Multiple Protection, Battery Management System for Solar Energy Storage Lithium-ion Battery Pack (20S 72V 80A)

Parameter：Voltage Value: 72VCharger Voltage:84VCharging current: Recommended below 10ATemperature protection: -20 ~ 70 ℃Applicable Battery:3.7V lithium ion Battery (Single Cell)Instantaneous CurrenT: 3 to 5 Times the working current.Package Contents:Battery Protection Board*1Cable*1Please note:Our products use the integrated IC solution.It means that the SOC accuracy of the BMS is very high, and the voltage of each string will be collected. It must be required that the voltage, internal resistance, and capacity must be the same height during assembly, otherwise the BMS will disconnect and protect (disconnection protection function).This product is an industrial semi-finished product, which needs to be repaired and assembled by people with professional electrical knowledge. Thank you for your understand.

• MULTIPLE PROTECTION Bisida 72V BMS has a variety of protection functions, such as Overcharge Protection, Overdischarge Protection, Overcurrent Protection, Short circuit Protection, Temperature Protection, Disconnection protection,Balance protection
• OPERATING TEMPERATURE Bisida's BMS Lithium Ion supports (3.7V) lithium-ion battery charging and discharging in zones from 2.65V to 4.25V, with low temperature protection up to -20°C and high temperature protection up to 70°C. (Different voltages and currents have different parameter details. Confirmation required.)
• WIRING METHOD The wiring methods of Common ports of BMS: B- connection battery pack negative , C- connection charging negative/output negative. All the positive electrodes are the total positive pole from the battery pack.
• NOTICE Before installing the BMS protective board, it is necessary to match the voltage, capacity, and internal resistance (the voltage difference between the battery per section is not higher than 0.05V, the difference between the internal resistance is not more than 5MΩ, and the capacity difference is less than 30mAh). Otherwise the battery pack will not be able to charge.
• EXCELLENT SOLUTION Bisida's BMS is manufactured using excellent protective integrated circuit IC and excellent Mosfet, making it robust, long-lasting and reliable
