　　How to remove a lithium polymer battery and what are the replacement tips?

　　The lithium polymer battery can be disassembled by loosening the negative electrode connector nut, disassembling the negative electrode connector, disassembling the positive electrode connector, disassembling the locking strap, etc. When replacing, pay attention to the order of disassembly and assembly of the positive and negative electrodes of the battery pack. Here is a detailed introduction "lithium polymer battery removal methods and replacement tips".

　　1. How to disassemble the lithium polymer battery

　　1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton, and you can see the two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut;

　　2. Disassemble the negative electrode connector: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the fastening block, and then pull out the negative electrode connector;

　　3. Disassemble the positive connector: Use the same method to disassemble the positive connector;

　　4. Disassemble the locking strap: Unscrew the nut used to fix the battery's locking strap, loosen the locking strap, and then take out the battery.

　　5. When installing a new battery, just follow the reverse steps. However, it should be noted that the order of installing the positive and negative connectors is "positive first, then negative", which is opposite to that of disassembly. The principle is the same, both to prevent the risk of short circuit and ensure safety.

　　2. lithium polymer battery replacement skills

　　1. The order of disassembly and assembly of the positive and negative poles of the battery pack is very particular.

　　When disassembling and assembling an old battery, be sure to proceed in the following order: disassemble the negative electrode first, and then disassemble the positive electrode. Because the car body is connected to the negative electrode of the battery (ground terminal), during the disassembly and assembly process, if the positive electrode is disassembled first , the screwdriver may touch the car body. Once touched, it is equivalent to directly connecting the positive and negative poles of the car body, which may cause the battery to short-circuit and burn. Therefore, when disassembling, the negative pole should be first, then the positive pole, but when installing, the order of positive pole first and then negative pole should be followed.

　　2. The battery replacement process is simple

　　In fact, battery replacement is very simple. As long as you prepare the tools and become familiar with the relevant precautions, it is not considered manual labor. Nowadays, most models of batteries are located in the engine compartment (the trunk of some pure electric vehicles), some are covered with protective shells, and some are directly exposed. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton. You can see two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut. Remove the negative electrode joint: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the joint block, and then remove the negative electrode joint head.

　　3. Remove the positive connection: use the same method to remove the positive connection.

　　Remove the locking strap: Unscrew the nut of the locking strap that secures the battery, then loosen the locking strap and remove the battery. Just follow the reverse steps to install a new battery, but be aware that the installation order of the positive and negative contacts is positive first and then negative. The installation order of the positive and negative contacts is the same as the order of disassembly and assembly, both to prevent short circuits. Danger, stay safe.
