1. First connect the negative electrode of the Yadi lithium battery.
2. Secondly, the conductive wire is used as the negative electrode for discharging, and the positive electrode for charging and discharging is derived from the main positive electrode of the battery.
3. Finally, connect the signal cable from the first red positive pole to the last black signal cable.
The wiring method between B+B-B1B2 of the 18650 lithium battery charging protection board
The assembly tutorial of the lithium battery is as follows:
Tools/Materials
Lithium batteries
Lithium battery fixed protection plate
1. Prepare the required materials, such as lithium batteries; Fixed skid plate, etc.
2. Place the individual lithium batteries in an orderly manner and secure them with silicone.
3. Use nickel material for series connection.
4. When connected in series, the battery core cannot be damaged and the battery cannot be connected reversely.
5. Connect the protection board, sort the cables and stick them with adhesive.
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 string of batteries is connected in turn until the last stringe B+; 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 should be between 2.8 and 4.2 V, and for a 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.
