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 will be pulled back to the perfect 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 . Note: This Link is Inductive Active Balancer: Will only balance two nearby batteries which voltage defference bigger than 0.2V Inductive energy transfer equalization board, high current 1.2A energy transfer battery voltage balancer, significantly balance battery voltage, improve the overall efficiency of the battery pack! 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. 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. Wiring definition: B-, the total negative pole of the battery pack (the negative pole of the first battery) B1, the positive electrode of the first battery B2, the positive electrode of the second battery B3...and so on. Note:Due to different production batches, there may be slight differences in the products, which will not affect normal use.The color of the harness is random and cannot be specified.
