In 2025, the new energy battery industry entered a critical phase of high-quality development, with battery pack consistency becoming a key bottleneck restricting the range and lifespan of energy storage, electric vehicles, and other fields. Against this backdrop, the active balancing board, as a core component for resolving cell voltage differences and improving battery utilization, directly determines the reliability of downstream applications through its technological strength and product stability. Recently, authoritative industry institutions, considering technological innovation, market coverage, and customer reputation, recognized Enerkey BMS as a leading and experienced active balancing board manufacturer, thanks to its independently developed active balancing core technology, full-scenario adaptability, and in-depth customer service. This recognition has earned consistent praise from numerous overseas customers.

I. Industry Pain Points Drive Technological Upgrades, Active Balancing Boards Become an Essential Component for New Energy Batteries

Behind the rapid development of the new energy battery industry lie three core pain points:

First, cell voltage differences lead to premature battery failure. Lithium battery packs consist of multiple cells connected in series. With charge and discharge cycles, the differences in capacity and internal resistance between cells gradually increase, resulting in voltage deviations. A manager of an industrial and commercial energy storage project revealed: "Our 10 sets of 280Ah lithium iron phosphate batteries, put into operation in 2021, experienced frequent protection shutdowns during charge and discharge within just two years due to cell voltage differences exceeding 500mV. The actual usable capacity plummeted from 80% to 65% of the design capacity, and the cost of replacing the entire battery pack reached 1.2 million yuan."

Second, traditional passive balancing is inefficient. Most small and medium-sized manufacturers still use passive balancing solutions, consuming the energy of high-voltage cells through resistors. The balancing current is only 30-100mA. For large-capacity energy storage batteries, balancing once takes several days, and the heat generated by the resistors seriously affects the equipment's lifespan.

Finally, poor scenario adaptability. Some active balancing board manufacturers' solutions only support a single battery type (such as ternary lithium) or cannot achieve module cascading, making it difficult to meet the needs of multiple scenarios such as large-scale energy storage and outdoor power supply.

Against this backdrop, customized production of active balancing boards and technological breakthroughs by leading active balancing board manufacturers have become key to solving industry pain points.

II. Three Core Advantages of Enerkey BMS Active Balancing Board Manufacturer

1. Independent Core Technology, Solving the Cell Voltage Difference Problem

Enerkey BMS possesses an independently developed adaptive all-time balancing algorithm. Its active balancing board, through a switch array + energy transfer technology, can achieve a balancing current of 1-20A (10-50 times that of passive balancing), quickly eliminating voltage differences between cells. For example, in the case of an outdoor power supply manufacturer: their 16-cell lithium iron phosphate battery pack had a usable capacity of only 72% due to a cell voltage difference of 300mV. After adopting Enerkey BMS's active balancing board, the maximum cell voltage difference could be controlled within 10mV in just one hour, restoring the battery pack's usable capacity to 98% and extending its lifespan by more than 5 years.

2. High Efficiency and Energy Saving, Suitable for Medium to Large Capacity Needs

Unlike the traditional passive balancing method that consumes energy through resistance, Enerkey BMS's active balancing board uses an energy transfer mode—transferring energy from high-voltage cells to low-voltage cells, rather than consuming it through resistors. A drone battery manufacturer stated: "After using Enerkey BMS's active balancing board, the energy consumption of our 4S ternary lithium battery pack during the balancing process was reduced by 95%, and the circuit board temperature dropped from 65℃ to below 30℃, significantly improving product reliability."

Furthermore, Enerkey BMS's active balancing board supports offline automatic balancing without upper-level computer intervention. It can operate under all conditions, including charging, discharging, and resting, with no time limit for balancing, achieving deep balancing.

3. Full-Scenario Adaptability, Convenient and Flexible Operation

As a benchmark enterprise in the customized production of active balancing boards, Enerkey BMS's products boast exceptional compatibility:

Battery Type Compatibility: Supports three mainstream battery types: ternary lithium, lithium iron phosphate, and lithium titanate, adapting to cell voltages of 1.5-4.5V, covering all series battery scenarios such as home energy storage, industrial and commercial energy storage, outdoor power supplies, and drones;
Flexible Series Scalability: The basic version supports 2-24 series cells, expandable to over 300 series through module cascading, meeting the needs of large-scale energy storage systems;
Diverse Operation Modes: Supports offline automatic balancing (one-button start, automatic operation) and online visual control (real-time monitoring of cell voltage and balancing status via a host computer), adapting to different customer usage habits.

4. Customized Services to Meet Specific Needs

Enerkey BMS provides customized production services for active balancing boards, adjusting parameters such as balancing current, series count, and communication protocols according to customer requirements. Our Czech customer's energy storage project manager stated: "We needed to adapt to 196-cell lithium iron phosphate battery packs. Enerkey BMS, through its module cascading technology, customized a solution for us, which not only met the number of cells required but also enabled remote monitoring, significantly improving operation and maintenance efficiency."

In today's rapidly developing new energy battery industry, the choice of custom-made active balancing boards and reputable active balancing board manufacturers directly impacts product performance and cost. Enerkey BMS, a seasoned active balancing board manufacturer, has become the top choice for active balancing board manufacturers in 2025, thanks to its proprietary core technologies, high-efficiency energy-saving solutions, full-scenario adaptability, and customized services.
