Active Balancer 4S 1.2A Inductive Balance 2-17S LiFePO4 Li-ion Battery

There is adjacent voltage difference of batteries when charging and discharging, which triggers the equalization of this inductive balancer. When the adjacent battery voltage difference reaches 0.1V or more, the internal trigger equalization work is performed. It will keep working until the adjacent battery voltage difference stops within 0.03V.

The battery pack voltage error will also be pulled back to the desired value. It’s effective to reduce battery maintenance costs. It can significantly balance battery voltage, and improve the overall efficiency of the battery pack.

Features

Adjacent differential pressure equalization
Max balance current 1.2A
Inductive energy transfer

Principle of equilibrium:

This module is adjacent to the differential pressure equalization, 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 pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error will be pulled back to the ideal value, reducing battery maintenance costs.

Voltage Equalization Accuracy

Adjacent voltage difference 30mV (typical)

Balanced Mode

Detect the nearby battery voltage difference. When it's greater than 0.1V, the equalization will be triggered. When it's less than 0.3V, it will stop working.

Equalizing Current

When the voltage difference is 0.1V, the equalizing current will be 0.5A. When the voltage difference is 0.2V, the equalizing current will achieve the max value of 1.2A.

Sleep Voltage

When the adjacent voltage is less than 0.03V, it will enter dormant state.

Static Working Current

0.01mA

Working Environment Temperature

-20℃~60℃

External Power

No need for external power supply, relying on the internal energy transfer of the battery to achieve the adjacent equalization.

Technical Parameters:

Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is not applicable.

Equilibrium current:

Adjacent pressure difference is 0.1V or more (current is about 0.5-0.7A);

Adjacent pressure difference is above 0.2V (maximum equalization current is 1.2A);

The smaller the differential pressure, the smaller the equalization current.

Note

2-4s and 2-8s inductive balancer has no LED indicator, and start balance when the voltage difference reaches 0.2V. Other models have LED indicator, and start balance when the voltage difference reaches 0.1V.

The inductive balancer is not recommended to be compatible with high series, the indicator will flash and report an error.

It cannot be used as a maintenance tool and the equalization efficiency is relatively low compared with our battery maintenance instrument.
