The connection sequence of the protection board to the battery and the main items::

Special attention: the cables of different manufacturers are not universal, please make sure to use matching cables;


1. Make sure that the cable is not inserted into the protection board before connecting the cable;


2. The cable starts from the thin black wire connected to the total negative electrode, the second wire (thin red wire) is connected to the first battery positive electrode, and then the positive electrode of each battery string is welded in the order of increasing voltage until the last positive electrode B+;


3. After the cable is connected, do not directly insert the plug. Measure the voltage between every two adjacent metal terminals on the back of the plug. (The voltage of the ternary polymer battery should be between 3.0 - 4.2V, and the lithium iron battery should be between 2.0 - 3.6. Between V)


4. After confirming that the wiring sequence and voltage of the cable are correct, insert the socket of the protection board;


5.
Same port protection board: B- connect the thick wire to the total negative electrode of the battery; C- connect the thick wire to the negative electrode of the charge and discharge; P- not connect; (port protection board: B- connect to the total negative electrode of the battery pack, C- connect to the charge Negative, P-connect to discharge negative)



The protection board is compatible with low series-Instructions for use: Mainly for cable connection (short-circuit the last positive cable)
Connection cable: Start with the black cable connected to the total negative electrode, and then weld to the positive electrode in the order of increasing voltage, The last extra cable is shorted to the last positive pole!
