โมดูล BMS ป้องกันแบตเกิน และปรับบาลานซ์แรงดันแบต Lithium 3 เซลล์ 3 String 12V18650 Lithium Battery Board 11.1V 12.6V With Equalization 25A Over-Current Over-Charge

 

1. Strictly according to the diagram wiring: 0V(B-), 3.7V(B1),7.4V (B2),11.1V (B+), Do not deliberately short circuit.

2. After the line is connected， Need to charge first,then have output.

3. When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use.

4. Do not mix the good battery and the poor battery.

5. The capacity of the battery internal resistance is closer will be better.

Note: Do not mix the good battery and poor battery to use.The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying.

 

TIPS: To achieve a better balance of balance, try to use a 13V switching source to charge (self-stopping current below 30mA). Because the balanced current balance of the IC in about 45mA, while the market mostly 12. 6V lithium battery charger, charging current detection below 100mA will stop, there is no balance there is no electricity charged, resulting in each group of battery voltage imbalance . On the battery voltage and output voltage drop pressure problem, this type of protection board works is negative protection, just a good combination of some batteries will have 0.1V-0.3V pressure drop, the cycle charge and discharge will be reduced several times Voltage drop voltage, which is normal. Charger as far as possible not to use 12V power supply, 3 string Keng battery is full of electricity is 12.6V, 12V power supply charge will appear full of the phenomenon, the protection board will not be protected, it has been charged, long-term use of the battery Life impact, thank you understand.
