How to connect the 18650 lithium ion battery 3.7v and what to do if smoke occurs?

　　The 18650 lithium ion battery 3.7v wiring method is to connect the positive pole to the negative pole, connect the batteries in series, lead out two power cords, and connect the air switch. In addition, if the battery smokes, first disconnect the battery input and output terminals. The most important thing is It means to completely separate it from flammable and explosive items, so let me introduce the relevant content in detail.

　　1. 18650 lithium ion battery 3.7v wiring method

　　1. It is recommended to use 6 square meters of wire for a 10KW UPS, and 4 square meters for a UPS below 10KW. The wire requires copper core.

　　2. The most important thing when installing a usp battery is to connect the battery. The key point of connecting the battery is to connect the positive pole to the negative pole, connect each battery in series, and then lead out two power cords, one positive pole and one negative pole connected to the air switch.

　　3. The battery power cord drawn out can be made into a plug and connected to the UPS host, and other sockets can be made on the UPS host.

　　4. There are two forms of host input, one is mains access, and the other is battery access. Mains access is 220V or 380V power supply, live wire is connected to L, and neutral wire is connected to N.

　　5. The battery is connected to the host through positive and negative connections. The positive terminal of the battery is connected to the positive terminal of the host, and the negative terminal of the battery is connected to the negative terminal of the host. Remember not to reverse the connection.

　　6. The output terminal is the power supply that can be connected to the device, which is the power supply we ultimately need. The host will automatically stabilize the voltage to avoid damage to the instrument caused by voltage shock.

　　2. How to deal with smoke from UPS batteries

　　1. Disconnect the battery input and output terminals.

　　2. Completely separate batteries from flammable and explosive items.

　　3. Analyze what type of product is used in the battery.

　　4. If you do not know how to handle it yourself, for the sake of safety, you can directly contact the manufacturer’s after-sales service to solve the problem.

　　5. Check the main cause of 18650 lithium ion battery 3.7v smoke.

　　6. After the 18650 lithium ion battery 3.7v is smoked, it needs to be professionally tested to determine whether it can be repaired. It also needs to undergo professional testing such as voltage to determine whether it can be used.
