Active Balancer 4s 2a (neey) (7421)

Product Details

The 4S 2A Lithium Battery Balance Board is a highly efficient balancing solution designed for 4-cell (4S) lithium battery packs. It helps maintain voltage consistency across all cells, enhancing battery lifespan and performance. By ensuring that each cell charges and discharges evenly, this balance board prevents overcharging, undercharging, and capacity imbalances that can lead to battery degradation over time. With a balancing current of 2A, this board efficiently redistributes excess charge from higher-voltage cells to lower-voltage ones, maintaining optimal balance without excessive power loss. It is compatible with Li-ion, LiFePO4, and Li-Polymer battery chemistries, making it versatile for various applications, including battery packs for e-bikes, power tools, energy storage systems, and DIY projects. The board operates passively, meaning it does not require an external power source to function. It automatically engages during the charging process, equalizing cell voltages efficiently. The compact design allows for easy integration into battery management systems (BMS), and its high-quality MOSFETs and resistors ensure reliable and long-lasting performance. For users seeking improved battery stability and longevity, the 4S 2A Lithium Battery Balance Board is a practical and cost-effective solution, minimizing the risks associated with cell imbalances and enhancing overall battery efficiency. Features:- Compatible Battery Types Efficient Balancing High-Quality Components Compact and Lightweight Design Overvoltage & Undervoltage Protection Technical Specifications:- Software active equalization specification Number of battery pack strings - 4S Balance current ≤2A Balance mode - Active equilibrium working temperature -20°C~60°C The 4S2A Active Balancer (NEEY) is a battery management solution designed for 4 series lithium-based battery packs. It supports 2A of current per cell for active balancing, which helps ensure that all cells in the battery pack are charged to the same voltage level. Active balancing optimizes battery performance by redistributing energy from higher-voltage cells to lower-voltage cells, thus improving the overall efficiency and lifespan of the battery pack. This balancer helps to prevent overcharging or deep discharging of individual cells, ensuring a safer and more reliable operation. The NEEY designation indicates the specific brand or model, offering efficient and effective cell balancing for applications such as energy storage systems, electric vehicles, and other lithium-based power solutions.
