Inductive energy transfer active equalization board Equilibrium principle: This module is adjacent differential pressure equalization. When the differential pressure of adjacent batteries reaches above 0.1V, the chip trigger the equalization to work until the differential pressure of adjacent batteries stops working within 0.03V. When it is used for charging and discharging on the battery pack, the adjacent differential pressure triggers the equalization to work. The battery pack voltage error also be pulled back to a more perfect value, reducing the battery maintenance cost. High precision energy transfer equalization, exclusive IC equalization, high current 1.2A energy transfer battery voltage balancer, significantly balancing the battery voltage, improving the overall efficiency of the battery pack Operating voltage range 2.0V-4.5V, common for ternary/lithium iron battery Equalizing current The adjacent differential pressure is above 0.1V (the current is about 0.5-0.7A) Adjacent differential pressure above 0.2V (up to the maximum equalizing current of 1.2A) The smaller the differential pressure is, the smaller the equalizing current is 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, positive pole of the second battery, B3, positive pole of the third battery, and so on Colour:black Material:PCB Different batches, product appearance and color may be different, which not affect the use Package Contents: 3 x Active Balancer Board 3 x Cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
