1. Inductive energy transfer balance card, current 1.2A energy transfer battery voltage balancer, significantly balances the battery voltage and improves the overall use efficiency of the battery pack! 2. By triggering the compensation function, the voltage error of the battery pack is corrected to an value, reducing battery maintenance costs. Working voltage: 2.0V 4.5V. 3. This board operates on the principle of adjacent compensation and cannot be used as a maintenance tool. It must be connected to the battery in conjunction with a lithium battery protection board. The voltage difference generated during charging and discharging activates the balancing board to achieve energy transfer and balance. 4. This module compensates for neighboring voltage differences. When the voltage difference between adjacent batteries exceeds 0.1V, the chip internally triggers compensation until the difference is within 0.03V, then stops functioning. It operates during charging and discharging when adjacent voltage differences occur.
