KLS 7S 24V 20A Li-ion BMS with Balance Wire and Temp Sensor for NMC Battery Power Packs Circuit Protection

Product-related information

Main Functions of the Individual Pins for Protecting the IC:

VDD Serves as the Positive Power Supply of the Protection IC.

VSS Functions as the Negative Power Supply of the Protection IC.

V- Acts as the Overcurrent and Short Circuit Detection Terminal of the Protection IC.

Dout Represents the Discharge Protection Terminal. Cout Denotes the Charging Protection Terminal.

The Working Process of the Protective Board

B+ and B- are respectively connected to the positive and negative terminals of the battery cells. P+ and P-

are respectively the positive and negative output terminals of the protection board. T is the NTC port for

temperature detection. The NTC port needs to work in conjunction with the MCU to safeguard the battery

temperature. Sometimes, this port is labeled as ID and is utilized for battery port identification.

Lithium Battery Protection Board: Ideal for Battery Energy Storage Protection of Electric Tools and Solar Lamps.

Boasting Stable Performance, Reliable Quality, and Exceptional Durability.

High-performance chips, MOS transistors and other high-quality components are selected to ensure the stable

operation of the circuit system.

This protection board is equipped with a rapid response function, Which can effectively safeguard the battery.

Wiring Precautions:

1. Installation of the protective board demands a certain level of technical expertise in electronics.

2. During the wiring process, initially connect the B- wire at the soldering pad location to the overall

negative terminal of the battery. It is essential that the B- wire be soldered to a short and thick wire.

Subsequently, solder the wired terminal to the battery pack first, and then insert the protective board.

3. The connection between the battery terminal B- and the protection board terminal B- must be short and thick.

Failure to do so may lead to premature charging and discharging of the protection board and subsequent malfunctions.

4. When wiring P+/P-, it is necessary to utilize thick wires. Excessively thin and long wires can cause the board to burn!
