4S BMS 12.8V LFP Battery Management System Aluminum Substrate with Balance Wire and NTC，Common Port,with Screw Connected Cable for Lifepo4 Battery Pack (4S 12.8V 100A)

Specifications:Standard voltage: 12.8VWorking current Max: 100AOperating power consumption: ≤40uAMain circuit conduction internal resistance: ≤ 15mΩTemperature range: -20 to +70°CDisconnection protection: YesBalancing current:≤45mADischarge:over discharge voltage :2.3V±0.08Vover discharge release :2.7V±0.1VTransient protection current: 3 to 5 times the working currentOvercurrent recovery condition: charge recovery/disconnect loadShort-circuit recovery condition: charge recovery/disconnect loadCharging:Assemble the battery pack, the voltage of a single battery string should be lower than 3.3Vover charge voltage :3.7V±0.05Vover charge release :3.5V±0.05VCharger voltage: 14.4VCharging current: Less than 50A (Recommended)Note:High current charging will cause the battery to heat upSize :65mm*150mm*17mm（Width*Length*Height）Cable size: 2.0MM pitch / 400MM length/5pinThe product includes:BMS*1Cable*1Instruction manual*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).When connecting to BMS for the first time, the cell voltage must be lower than 3.3V. If it exceeds 3.4V, it will easily trigger the overcharge protection and the BMS will not be activated.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’s 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 (3.2V) Lifepo4 battery charging and discharging in zones from 2.3V to 3.7V, 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. Please communicate with the seller to confirm accurate data)
• 【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). When connecting to the BMS for the first time, the cell voltage needs to be lower than 3.3V. If the battery voltage difference is too large, the battery pack will not be able to charge.
• 【Wiring Method】The wiring methods of Common ports of BMS: B- connection battery pack negative , P- connection charging negative/output negative. All the positive electrodes are the total positive pole from the battery pack. Repair and assembly are only recommended for personnel with professional electrical knowledge
• 【High Quality】Bisida's BMS utilizes top quality (A-level) protective integrated circuit IC, from the solution of Industry car level.BMS manufactured by high quality Mos and IC .
