13S 1.2A Large Current Lithium Battery Active Equalizer PCB Battery Balancer Board for Lifepo4 Item Type: Lithium Battery Active Equalizer Mode: EK L13S1A Material: PCB Board Size (excluding lines): Approx. 88 x 80 x 8mm / 3.46 x 3.15 x 0.31in 1. Balance Indication: A. When the equalization light is on, the equalization work is turned on. b. The equalization light goes out, and the equalization circuit sleeps, C. The balance light flashes, the string indicator is lost, or the circuit is faulty. 2. Principle of Balance: The adjacent voltage difference of this module is balanced, and the voltage difference between adjacent batteries reaches above 0.1V. The internal trigger balance works continuously until the voltage difference between adjacent batteries stops within 0.03V. There is an adjacent pressure difference during battery pack charging and discharging. After triggering equalization, the voltage error of the battery pack will be pulled back to the ideal value, reducing battery maintenance costs. 3. Technical Parameters: The working voltage is 2.0V-4.5V, which is commonly found in ternary lithium iron batteries. Lithium cobalt oxide batteries are not suitable. Balance Current: Adjacent voltage difference above 0.1V (current approximately 0.5-0.7A); Adjacent voltage difference above 0.2V (maximum balanced current 1.2A); The smaller the voltage difference, the smaller the equilibrium current. 4. Wiring Definition: B. Total negative electrode of the battery pack (negative electrode of the first battery) B1. Positive electrode of the first battery section B2. Positive pole of secondary battery
