Many people don't know the role of lithium battery protection board. Lithium battery protection board, as the name suggests, is used to protect lithium batteries. The role of lithium battery protection board is to protect the battery from over-discharge, over-charge, and over-current, as well as output short-circuit protection.

　　The lithium battery protection board is a protection for the charging and discharging of the series lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), and realize the equal charge of the individual cells of the battery pack , Which effectively improves the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single battery in the battery pack to protect and extend the battery life; undervoltage protection makes every A single-cell battery is used to avoid damage to the battery due to over-discharge.

　　The finished lithium battery has two main components: lithium battery core and protective plate. The lithium battery core is mainly composed of positive plate, diaphragm, negative plate and electrolyte; positive plate, diaphragm, negative plate are wound or laminated, packaged, and filled with electrolyte. , After packaging, it is made into batteries. Many people don't know the role of lithium battery protection board. Lithium battery protection board, as the name suggests, is used to protect lithium batteries. The role of lithium battery protection board is to protect the battery from over-discharge, over-charge, and over-current, as well as output short-circuit protection.

　　36v lithium battery protection board wiring

　　1. Connect 12 batteries in series first. If there are 24 sections, you can connect them in parallel and then in series!

　　2. Connect the negative pole of the battery pack according to B. In turn B1_B2_B3, ,, B10_B1l_B2

　　3, the same interface:

　　The positive electrode of the battery pack is the positive electrode for charging and discharging. C-: A negative electrode that can be used as a negative electrode for charging and discharging.

　　4, sub-interface:

　　The positive electrode of the battery pack is the positive electrode for charging and discharging.

　　C-: It can be used as a negative electrode for charging.

　　D-: It can only be used as the negative electrode of discharge.
