Active Balancer 17-21s 5a (neey) (5424)

Product Details

The NEEY Active Balancer 17-21S 5A is an advanced battery balancing module designed for lithium-based battery packs, including LiFePO₄, Li-ion, and LTO chemistries. This balancer ensures optimal performance and longevity by equalizing the voltage across all cells in the battery pack. Features:- Capacitive Energy Transfer: Employs a patented capacitive architecture for efficient energy redistribution among cells. Automatic Balancing: Initiates balancing when the voltage difference between adjacent cells exceeds 0.1V, with current up to 5A. No Need for External Power Supply: Operates solely on the energy from the battery pack, simplifying installation and reducing complexity. Real-Time Monitoring: Some models support Bluetooth connectivity for real-time monitoring via a mobile app. Safety Features: Includes under-voltage protection to prevent damage to the battery pack. Technical Specifications:- Software active equalization specification Number of battery pack strings - 21S Balance current ≤5A Balance mode - Active equilibrium working temperature -20°C~60°C The 21S5A Active Balancer (NEEY) is a battery management solution designed for 21 series lithium-based battery packs. It supports 5A of current per cell for active balancing, which ensures that all cells in the battery pack remain at a balanced voltage level. Active balancing redistributes energy from cells with higher voltage to those with lower voltage, optimizing the overall performance and efficiency of the battery. This helps prevent individual cells from becoming overcharged or discharged excessively, extending the lifespan and enhancing the safety of the battery pack. The NEEY model is known for its reliable performance in applications such as energy storage systems, electric vehicles, and other high-demand lithium battery applications.
