Li-Ion Battery BMS 30V BMS 7S 30A With NTC Lithium Battery Board For Battery Management System
The addition of BMS to lithium batteries is determined by the characteristics of lithium batteries. Lithium batteries have safe discharge, charging, and overcurrent limits. The purpose of adding BMS is to ensure that these values do not exceed the safe range when using lithium batteries.
Lithium batteries have limited requirements during the charging and discharging processes. Take the famous lithium iron phosphate battery as an example: charging generally cannot exceed 3.9V, and discharging cannot be lower than 2V.
Otherwise, the battery will be damaged due to overcharging or over-discharging, and this damage is sometimes irreversible.
Usually, adding BMS to a lithium battery will control the battery voltage within this voltage to protect the lithium battery. The lithium battery BMS realizes equal charging of every single battery in the battery pack, effectively improving the charging effect in series charging mode.

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!
