Description

Product Description

BMS for lithium battery
Why are BMS for lithium battery so important? These batteries are very powerful, but their reactions to misuse can be dangerous. Therefore, it is necessary to monitor each electrochemical cell to prevent such cases of unauthorized use.

This monitoring work is carried out thanks to an electronic management card called BMS “Battery Management System”

Lithium cells are very sensitive to their environment: If they are exposed to too severe conditions (voltage, temperature) or if they are subjected to shocks, this can lead to safety problems in the battery.

As the electrolyte is liquid, the risk of short-circuit due to leakage can quickly become dangerous. The liquid reacts with air or water and becomes extremely corrosive.

The critical cases are:
Overcharging
Exposure to too high or too low temperatures
Over-discharge followed by recharging
Short circuit
The consequences of these critical cases are:
A significant decrease in battery performance
Decreased battery life
The risk of fire

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
