Balance indication: 1. When the equalization light is on, the equalization work is turned on. 2. The equalization light goes out, the equalization circuit sleeps, 3. The equalization light flashes, indication is lost, or the circuit is faulty. Principle of equilibrium: This module is adjacent to the differential pressure equalization, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential pressure when charging and discharging on the battery pack. Trigger equalization, the battery pack voltage error be pulled back to the ideal value, reducing battery maintenance costs. Technical Parameters: Working voltage is 2.0V-4.5V, ternary iron lithium battery is common, lithium cobalt oxide battery is . Equilibrium current: Adjacent pressure difference is 0.1V or more (current is about 0.5-0.7A); Adjacent pressure difference is above 0.2V (maximum equalization current is 1.2A); The smaller the differential pressure, the smaller the equalization current.
