4S 6A Active Balancer Super Capacitor Equalizer Price in Bangladesh

The 4S 6A Active Balancer Super Capacitor Equalizer is a high-current active balancing module designed to reduce voltage differences between individual cells in a 4S lithium battery pack. Unlike simple passive balancing circuits that dissipate excess energy as heat through resistors, an active balancer transfers energy between cells, making the balancing process more efficient.

A 4S battery pack contains four cells or four cell groups connected in series. The overall pack voltage is the sum of the individual cell voltages, but each cell can develop a different voltage during charging and discharging. These differences can occur because of variations in cell capacity, internal resistance, age, temperature, state of charge, and operating conditions.

When cells become unbalanced, one cell may reach its upper voltage limit before the others during charging, while another cell may reach its lower limit earlier during discharge. This can reduce the effective usable capacity of the entire battery pack. An active equalizer helps address this problem by transferring energy between the cells.

The 6A rating represents the maximum balancing-current capability of this class of module. The actual balancing current is not necessarily a constant 6A; it depends on the voltage difference between the cells and the particular board design. Some published specifications for comparable 6A active equalizers indicate that balancing current increases with cell-voltage difference and can approach the rated maximum under larger differences.

The term “super capacitor equalizer” refers to the capacitor-based energy-transfer architecture used by this type of active balancing circuit. Capacitors and switching components are used to transfer energy between battery sections instead of simply burning excess energy as heat. Similar capacitor-based active balancers are available for Li-ion, LiFePO4 and LTO battery configurations.

The 4S 6A Active Balancer can therefore be useful in battery systems where maintaining closer voltage matching between series-connected cells is important. Typical applications include DIY battery packs, energy-storage systems, portable power equipment, robotics, backup-power projects, and other compatible lithium battery systems.

It is important to understand that an active balancer is not automatically a complete BMS. Its primary purpose is cell equalization. A complete battery system may still require a suitable BMS for overcharge, over-discharge, over-current, short-circuit, temperature, and other protection functions.

The balancer should also be matched to the exact battery chemistry and cell voltage range. Li-ion, LiFePO4, and LTO cells have different voltage characteristics, so users should verify the specifications of their particular module before connecting it to a battery pack.

For battery pack builders who need stronger balancing capability than a small 1A-class module, a 4S 6A active balancer can provide a higher-current energy-transfer solution while keeping the overall circuit compact.

What is an Active Super Capacitor Battery Equalizer?

An active super capacitor battery equalizer is a circuit designed to redistribute energy between cells in a series-connected battery pack.

Instead of using resistors to convert excess energy into heat, the active circuit uses switching components and capacitive energy storage to transfer energy from a relatively higher-voltage cell toward lower-voltage cells.

This approach is known as active balancing or active equalization. Comparable capacitor-based balancers are marketed for lithium-ion, LiFePO4 and LTO battery packs.

Working Principle of 4S 6A Active Balancer Super Capacitor Equalizer

The module monitors the voltage of the four individual cells or cell groups in a 4S battery pack.

When there is a voltage difference between the cells, the active balancing circuit uses switching electronics and capacitive energy transfer to redistribute energy between the battery sections.

For example, if one cell has a higher voltage than another, energy can be transferred away from the relatively higher-voltage cell toward a lower-voltage cell. This gradually reduces the voltage difference.

The process is different from passive balancing. A passive balancer typically uses a resistor to consume excess energy from a higher-voltage cell. An active balancer instead attempts to transfer useful stored energy between cells. Comparable capacitor-based designs use the entire battery group for energy conversion rather than relying only on resistive discharge.

The actual balancing current depends on the voltage difference and the particular circuit. Therefore, the 6A specification should be understood as a maximum or rated balancing capability rather than a constant current that flows continuously.
