18650 Battery Pack Balance Protection Board for Rv Large Trucks Mkbms

ATTENTION: It is strictly forbidden to insert balance wires into BMS before connecting batteries.Must make sure that the cable is soldered correctly first , and then connect the BMS board.The sequence of connecting wires for BMS: From thin black balance wire to stare, the 2ndwire(thin red wire)connect with the 1stbattery's positive pole.Then connect each cell's positive pole in order until the last one B+.Please do not insert the plug directly after the cable is connected.Measure the voltage between each two adjacent metal terminals on the back of the plug. If it is a ternary polymer battery, the voltage should be between 3.0 ~4.2V, and the voltage of the iron-lithium battery should be between 2.0 ~3.6V. The voltage should be between 1.5~2.75V.After confirming that the wiring sequence and voltage of the cables are correct, insert them into the socket of the protection board. Attentionplease: The cables of different manufacturers are not universal, please make sure to use the matching cables.After the wiring is completed, measure whether the voltage of battery B+and B- ,andthe voltage of B-and C- are equal. If they are equal, the protection board is working normally and can be used normally. If it is not equal, please check the wiring again.Product Description:Charging current: less than or equal to 10ADischarge current: 30AInternal resistance: less than or equal to 15m ohmCharging voltage:The number of Li-ion batteryin series connection X 4.2VWiring : Same PortOvercharge protection:Detection voltage: 4.25 +/- 0.025VDetection delay: 1000 +/- 500MSRelease voltage: 4.15 +/- 0.05VOver-discharge voltage protection:Detection voltage: 2.75 +/- 0.1VDetection delay: 1000 +/- 500MSRelease voltage: 3.0 +/- 0.1VShort circuit protection:Trigger condition:external short circuitDetection delay: 300usRelease condition: disconnect the loadTemperature control protection:Charge and discharge over-temperature protection: 55Charge and discharge high temperature release temperature: 75Release condition:During normal working temperatureSelf-consumption:Working power consumption: less than 35UAOver-discharge power consumption(Sleeping State): less than 10UAOperating temperature range: -30~+80CColour: silver + greenMaterial: composite materialPackage Contents:1 * 4-7S BMS PCBA board1 * HY2.0 single head 8P lineOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
