BMS battery pack protection board function description: Support :
8S -32S lifePo4 battery (Lithium iron phosphate battery cell)
Single cell voltage detection range 1V-4.6V. High precision detection cell voltage error is less than 5MA Charging current 50A Discharge current: 200A Balance current :200MA . Controlled balance mode, when the charging is started, the voltage difference can be detected by the detected voltage difference to be greater than the set value. High-precision coulomb counter function temperature control detection Hall speed measurement
Bluetooth connection : support for android/iphone IOS phone
Support cells :Support Lifepo4
Voltage accuracy :Single cell voltage detection range (1.5-4.6V), so support a variety of cell use, accuracy error within 3 mV
Drop wire protection :detect wire not weld well and cause the voltage is wrong.balance wire drop cell protection
Overcharge protection: Connect to Bluetooth to set high-precision detection voltage, single overcharge protection and total voltage overvoltage protection
Over discharge protection : Connect Bluetooth to set up high-precision detection voltage, single-cell over-discharge protection and total voltage under-voltage protection
Short circuit protection: Can be connected to Bluetooth to set the short circuit protection value, change to 0 is turn off short circuit protection
Overcurrent protection: can be connected to Bluetooth to set up the overcurrent protection value (maximum 300A)
Current detection: within the current range of the purchased protection board
Temperature control protection: The protection board has built-in balanced temperature control, power temperature, and can be connected with 4 temperature controls to prevent high temperature danger.
balance current: 200 mA, high voltage versus low voltage discharge balance
Discharge current: refer to the current in the purchase selection as the peak discharge current
Charging current: less than 50A
Connection internal resistance: based on current to time scoring, accurately calculate the remaining battery capacity and charging current
Note: The cable is connected from the first black wire on the far right to the total negative electrode of the battery pack, which is the negative electrode of the first cell of batteries.
Then start from the black wire and start from the first white wire from right to left to the first cell, second cell, third cell of the battery and so on, and connect to the positive electrode of each cell in sequence. The minimum number of cells to be connected is 8S, and the batteries of less than 32S are not left empty. After connecting, use a multimeter to measure the voltage on the plug row. There is no problem to confirm that the voltage is correct before plugging into the protection board The same wire is connected to a red wire, regardless of its color), note that the last red wire on the third and last socket is B + which supplies power to the protection board. It is connected to the cable of the last cell of batteries. That is to say, two wires need to be connected to the bms on the last positive pole of the battery. There is a hole behind the last red wire of the third socket and B + is redundant. You can leave it alone. Other instructions are the same as the 24S protection board
