4s 2a Lifepo4 li-ion Active Lithium Battery Equalizer Balance Board BMS
[Lithium Battery Protection Board] The 4S 2A Active Balancer Equalizer is designed to keep lithium battery cells balanced during both charging and discharging. It continuously monitors the voltage of each cell in the battery pack. When a voltage difference appears, the module transfers energy from higher-voltage cells to lower-voltage cells. As a result, all cells remain balanced and the battery pack works more efficiently. Unlike passive balancing systems, this module does not waste energy as heat. Instead, it redistributes energy between cells. Therefore, the battery pack becomes more efficient and lasts longer. In addition, the balancer automatically starts working when the voltage difference between adjacent cells reaches 0.1V. The balancing process continues until the difference drops to about 0.03V. Because of this smart balancing system, the battery pack stays stable and reliable. This module is suitable for 4S lithium battery packs, including both LiFePO4 and Li-ion batteries. It is commonly used in solar energy storage systems, electric vehicles, and DIY battery projects. 🔹 Key Features Supports 4S LiFePO4 and Li-ion battery packs Active energy transfer balancing Maximum balancing current up to 2A Improves battery efficiency and lifespan Reduces voltage differences between cells Low heat generation compared to passive balancers Automatic balancing during charging and discharging 🔹 Technical Specifications Parameter Specification Battery Type LiFePO4 / Li-ion Battery Series 4S Balance Method Active balancing Maximum Balance Current 2A Operating Voltage Range 2.0V – 4.5V Balance Start Voltage Difference ≥ 0.1V Maximum Balance Current Condition ≥ 0.2V difference Balance Stop Difference ~0.03V Operating Temperature -20°C to 60°C 🔹 Applications This active balancer is suitable for many battery systems, such as: Solar battery packs DIY lithium battery packs Electric scooters and bikes Energy storage systems Backup power systems 🔹 Package Includes 1 × 4S 2A Active Balancer Module
