Inductive energy fer balance board, high current 1.2A energy fer battery voltage balancer, significantly balance the battery voltage and improve the overall efficiency of the battery pack! Balance Instructions: 1. When the equalization light is on, the equalization work is turned on, 2. The equalization light is off, the equalization circuit is in sleep state, 3. The equalization light flashes, indicating that is dropped, or the circuit is faulty. Equilibrium principle: This module is the balance of adjacent voltage difference, the voltage difference between adjacent batteries reaches 0.1V or more, and the chip trigger the balance work, until the voltage difference between adjacent batteries is within 0.03V and stop working. When it is used on the battery pack, there is adjacent voltage difference when charging and discharging. Triggering the equalization work, the battery pack voltage error also be pulled back to an ideal value, reducing battery maintenance costs. technical parameter: The working voltage is 2.0V-4.5V, the ternary iron lithium battery is common, and the LTO lithium titanate battery is not suitable. Balance current: The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A); The adjacent voltage difference is more than 0.2V (the maximum equilibrium current is 1.2A); The smaller the voltage difference, the smaller the equalizing current. Wiring Definition: B-, the total negative pole of the battery pack (the negative pole of the first battery) B1, the positive pole of the first battery B2, the positive pole of the second battery B3...and so on.
