4S 1.2A Active Equalizer Board for Lithium Iron Batteries

[POWERFUL HIGH CURRENT BALANCING] Inductive power transfer technology delivers up to 1.2A of balancing current, significantly reducing voltage differences between batteries. This high-performance active equalizer improves overall battery efficiency and extends battery life, making it ideal for maintaining 4S lithium iron batteries during charge and discharge cycles. [SMART AUTOMATIC EQUALIZATION] The module automatically activates when the adjacent voltage difference exceeds 0.1V, providing a balancing current of 0.5-0.7A. It continues to operate until the voltage difference drops to 0.03V, ensuring accurate and efficient battery voltage balancing without manual intervention or complex setup. [LOW POWER CONSUMPTION DESIGN] Built with an enhanced ultra-low internal resistance MOSFET, this balancer boasts a static power consumption of less than 20 μA. The balancing current intelligently adjusts from 0 to 1.2 A depending on the voltage difference, meaning smaller voltage differences result in lower current draw for optimal energy efficiency. [RELIABLE PCB CONSTRUCTION] Made from high-quality PCB materials, this active equalizer board offers excellent durability, reliability, and miniaturization. Its compact design ensures good maintainability and interchangeability, making it easy to install and replace in your battery management system without taking up too much space. [WIDE COMPATIBILITY AND SAFE OPERATION] Operating over a voltage range of 2.0 V to 4.5 V, this balancer is compatible with lithium and lithium iron ternary batteries. Note that it is not suitable for LTO lithium titanate batteries. The clear wiring definition for B-B1, B2, B3, and B4 allows for simple connection to your battery. 4S.
