Ziqqucu 3A Active Equalizer Whole Group Balancer Lifepo4 Lithium Active Battery Energy Transfer Equalization Capacitor

Features:

1.High efficiency, high precision，

2.Low heat, high reliability，

3.Long service life, capacitor bank A is connected in parallel with the battery line bank to improve the transfer efficiency，

4.It is applicable to battery pack, maintenance and DIY battery pack.

5.Protection switch: when the voltage is lower than 2.5V, it will automatically stop and enter the sleep state to reduce the damage to the battery.

Parameters:

Current: The battery pack can be used within 2Ah-400Ah, but the larger the capacity, the longer the equalization time

Maximum equalizing current: 3A (at 1.2V differential pressure)

Equalizing voltage accuracy: 0.01V

Suitable ambient temperature: - 25 ° C to+75 ° C

Equalization starting condition: always equalizing, the greater the voltage difference, the greater the equalizing current

Principle of equalization mode: capacitor energy transfer

Static current loss: about 2-6mA (slightly different from 4S-8S)

Low voltage protection of battery: the battery is automatically closed and balanced when the monomer is lower than 2.5V

External equalizing switch: can be externally connected (generally not required)

Main body appearance size:

4S：62mm*50mm

6S：73mm*62mm

8S：92mm*62mm

Suitable battery type: 3.2V-4.4V (lithium iron phosphate/lithium ternary, etc.)

Working principle:

Through the program control of the single chip computer, the individual battery transfers electric energy to the individual capacitor B. After splitting, the whole group of capacitor c is paralleled to equalize the voltage, and so on. Simply understood, it is a series of battery packs. The batteries are connected in parallel to equalize the electric energy. The advantages are high efficiency, high accuracy, low heating and high reliability.

Low ESR electrolytic capacitor is used for capacitor, with long service life and high reliability. Capacitor bank A is connected in parallel with battery line bank to improve transfer efficiency

External switch (generally not required):

The circuit power consumption is only about 2mA and the battery voltage is lower than 2.5V.

The circuit is always working by default. If an external switch is required under special circumstances, the connecting copper foil in the middle of the S pad can be cut off with a knife, and a conventional switch can be installed from the connecting wire of the pad to control the opening and closing of the circuit.

Be careful:

B - is the total negative of the battery pack. Carefully check and plug in the plug again. Wrong wiring sequence will burn the chip
