Description

Product Description

The function of the BMS is mainly to protect the cells of lithium batteries, maintain safety and stability during battery charging and discharging, and play an important role in the performance of the entire battery circuit system.

Most people are confused as to why lithium batteries require a lithium battery protection board before they can be used. Next, let me briefly introduce to you why lithium batteries require a lithium battery protection board before they can be used.

Descriptions:
1. Using high-quality materials, durable
2. Fast heat dissipation, balanced protection
3. When the battery is fully charged, it will protect
4. When the battery discharge reaches a certain level, the battery will discharge protection
5. To prevent the battery current from being too large, the battery will be protected against overcurrent
6. Prevent the battery from short circuit and protect the battery from short circuit
7. When the battery temperature reaches a high level, it will protect the battery balance

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!
