ACTIVE BALANCER 4S 1A H/W DALY (48e8)

Product Details

The Daly Active Balancer 4S 1A H/W (48e8) is a hardware-based active battery balancer designed for 4-series (4S) lithium-ion or LiFePO₄ battery packs. It enhances battery performance by equalizing voltage differences between individual cells, thereby improving overall battery consistency and extending its lifespan.Key Specifications Number of Cells: 4S (4 cells in series) Balancing Current: Up to 1A Balancing Mode: Active equalization Activation Threshold: Typically 20–30mV voltage imbalance between cells Operating Temperature: -20°C to 60°C Power Consumption: Approximately 250µA during operation; 88µA in sleep mode Dimensions: 60 x 36 x 18 mm How It Works The active balancer redistributes energy from higher-voltage cells to lower-voltage ones through an energy transfer mechanism. This process balances the cells without significant heat generation, unlike passive balancing methods that dissipate excess energy as heat. By maintaining cell voltage uniformity, the balancer helps prevent overcharging or deep discharging of individual cells, which can lead to premature battery degradation.Because the battery capacity, internal resistance, voltage and other parameter values are not completely consistent,this difference causes the battery with the smallest capacity to be easily overcharged and discharged during charging, and the smallest battery capacity becomes smaller after damage, entering a vicious cycle. The performance of single battery directly affects the charge and discharge characteristics ofthewhole battery and the reduction ofbattery capacity.BMSwithout balance function is just a data collector,which is hardly a management system.BMS active equalization function can realize the maximum continuous 1Aequalization current.Transfer the high-energy single battery to the low-energy single battery, or use thewhole group of energy to supplementthe lowest single battery.During the implementation process,the energy is redistributed through the energy storage link, so as to ensure the battery consistency to the greatest extent, improve the battery life mileage and delay the battery aging.
