What is the wiring method between B+B-B1B2 of 18650 lithium battery charging protection board? First of all, cables from different manufacturers are not universal. Please make sure to use suitable cables: 1. Before connecting the cable, make sure that the cable is not inserted into the protection plate. 2. Solder line B (blue). thick line) from the protective plate to the total negative electrode of the battery; 3. The cable layout starts from the thin black wire connected to B-, the second wire (thin red wire) is connected to the positive terminal of the first string. batteries, then the positive terminal of each battery string is connected in turn until the last B+ string; 4. The cables are connected. Do not insert the rear plug directly into the protection plate. Measure the voltage between each of two adjacent metal terminals. If it is a ternary polymer battery, the voltage shouldbe between 2.8 and 4.2 V, and for lithium iron battery, it should be between 2.5 and 3.65 V, lithium titanate battery should be between 1.6 and 2 ,8. V; ⑤ After the wiring sequence and voltage are confirmed, insert it into the socket of the protection board.
How to connect two keys for lithium battery
The lithium battery protection board cable has a black wire.
The wiring sequence of the protection board connection battery:
①Before connecting the cable, make sure that the cable is not inserted in the protection plate.
② Weld line B (thick blue line) of the protection plate to the total negative electrode of the battery.
③Wiring starts from the thin black wire connecting B-, the second wire (thin red wire) connects the positive terminal of the first battery string, then connects the positive terminal of each battery stringies in sequence until the last B+ string.
④After the cable is connected, do not insert the plug directly into the protection plate. Measure the voltage between two adjacent metal terminals on the back of the plug. If it is a ternary polymer battery, the voltage. should be between 2.8~4.2V, lithium iron battery should be between 2.5~3.65V and lithium titanate battery should be between 1.6~2.8V.
⑤After confirming that the wiring sequence and voltage are correct, insert the protection board plug into the lithium battery protection board wiring tutorial.
Special note: Cables from different manufacturers are not universal, please be sure to use matching cables: ① Before connecting the cable, make sure that the cable is not inserted into the protection plate ② Connect the B-; The line (thick blue line) from the skid plate to ) ist welded to the total negative electrode of the battery ③ The cable starts from the thin black wire connected to B-, the second wire (thin red wire) is connected to the positive; electrode of the first battery string, then connected to the positive electrode of each battery string in turn, until the last B+ string; ④After the cable is connected, do not insert the plug directly into the protection plate. each two adjacent metal terminals on the rear of the plug. If it is a ternary polymer battery, the voltage should be between 2.8-4.2V, and for lithium iron battery, it should be between 2.5-~3.65V .Lithium titanate battery should be 1.6-2.8V; ⑤ After the wiring sequence and voltage are confirmed, insert it into the protection board socket
