Smart BMS 6S 7S 30A Lithium Battery BMS Li-Ion Battery Cell Protection Board 25.2V 29.4V BMS For RV
Product Description
Lithium battery protection board market prospects
During the use of lithium batteries, overcharging, over-discharging, and over-discharging will affect the service life and performance of the battery. In severe cases, it will cause the lithium battery to burn or explode. There have been cases of mobile phone lithium batteries exploding and causing casualties.
IT often occurs and the recall of lithium battery products by mobile phone manufacturers.Therefore, each lithium battery must be equipped with a safety protection board, which consists of a dedicated IC and several external components.
Through the protection loop, it can effectively monitor and prevent damage to the battery, prevent overcharge, over-discharge, and short circuit from causing combustion, explosion, etc.

Wire Diagram
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!
