Enerkey 4S 80A BMS for 12V 11.6V Li-ion Battery Pack BMS Factory BMS 4S 3.2V 3.7V Battery Cell
How does BMS work?
(1) Monitor the battery
A BMS may monitor the state of the battery and it triggers a power module shutdown if the data is out of range.Monitoring the voltage of each cell is critical to the health of the battery,
and lithium-ion battery BMS usually provides each cell with an operating voltage window in charging and discharging to avoid battery degradation.Because lithium battery cells are very sensitive to overcharging and over-discharging,
and cells imbalance can lead to thermal runaway and cells degradation.It will decrease the efficiency and short the life span of the battery. Battery cells' operating voltage is between 2.5V and 4.2V depending on the lithium chemistry used.
Running the battery beyond this range will result in a significant reduction in battery life and may even damage the battery.
(2) Protect the battery
A Battery Management System (BMS) can monitor and control the charging and discharging process to ensure that the battery stays within its safe operating range.
Overcharge Protection/Overdischarge Protection
BMS estimates the battery's SOC based on voltage and current measurements. This allows the BMS to predict when the battery has reached its current limit and once the battery voltage is above/below the safe limit, the BMS will limit the discharge current or terminate the discharge.
Overvoltage Protection/Undervoltage Protection:
BMS prevents overvoltage/undervoltage by limiting the charging current or stopping the charging process. When the battery's voltage is higher/lower than the safe voltage, the BMS will shut down the charging circuit to prevent damage to the battery.
Temperature Protection
Overcharge and overdischarge can cause the battery temperature to rise or even cause thermal runaway. BMS helps reduce this risk by monitoring battery temperature and taking action when the temperature exceeds its safe operating range.
(3) Short Circuit Protection
The battery management system (BMS) continuously monitors voltage, current and other parameters to prevent short circuit. Faulty wiring will cause short circuit which poses a significant risk to both the battery and the connected device. And BMS can protect the battery from short circuit.
(4) Balance the battery
Unlike lead-acid, the voltage of a fully charged lithium battery rises quickly. If not controlled in time, it may cause battery degradation. There will be a big perform difference between battery cells which may cause the malfunction within the safe voltage range.

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!
