Enerkey 11.1V 12.6V 3S 50A Lithium Battery BMS Board For Electeic Two Whellers 18650 Battery Li-Ion BMS 3S 12V
This series of lithium battery protection boards is a power
management system (BMS) tailor-made for ternary lithium batteries.
This series of lithium battery protection boards uses
automotive-grade MOS, 2oz thickened copper foil and copper strips
for current sharing, making the protection board highly precise,
with ultra-low internal resistance and ultra-low heat generation
If the voltage of a certain cell in a battery pack is higher than that of other cells, this cell will reach the dangerous voltage first during the charging process. At this time, the overall voltage of the battery pack has not yet reached the full value, and the charger will not stop charging.
Therefore, the cells that reach dangerous voltages first will cause safety risks. Therefore, controlling and monitoring the total voltage of the battery pack is not enough for lithium-based chemistries. The BMS must check the voltage of each individual cell that makes up the battery pack.

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!
