4X 4S 1300MA Active Equalizer Balancer 18650 Lithium Lifepo4 Battery Protection Board BMS Board Transfer Board

4X 4S 1300MA Active Equalizer Balancer 18650 Lithium Lifepo4 Battery Protection Board BMS Board Transfer Board Description

About the Principle of balance: This module is adjacent to the differential voltage balance, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential voltage when charging and discharging the battery pack. Trigger balance, the battery pack voltage error will be pulled back to the perfect value, reducing battery maintenance costs.
Balanced BMS Features: High-precision transfer equalization, exclusive balanced IC, high current 1.3A transfer battery voltage balancer, significantly balancing battery voltage, improving overall battery pack efficiency.
Operating voltage range: 3.0-4.5V, Li-ion/Lipo/Lifepo4/18650 lithium battery universal.

Balance current:
Adjacent voltage difference is 0.1V or more (current is about 0.5-0.7A);
Adjacent voltage difference is above 0.2V (maximum balance current is 1.3A);
The smaller the differential voltage , the smaller the balance current.
About Connect:
B-, the total negative pole of the battery pack (the negative pole of the first battery)
B1, the positive electrode of the first battery
B2, the positive electrode of the second battery
B3, the positive electrode of the third battery
And so ..........
About the Indicator:
1.The indicator is lighting,it mean the Active balancing work for between the batteries.
2.The indicator is no lit,the equalization have been completed or not reach for start- balancing.
3.The indicator is flash,the equalization not work.
