1. This board operates on the principle of adjacent compensation and is not intended for use as a maintenance tool. To connect to the battery, it must be paired with a lithium battery protection board. The voltage difference generated during charging and discharging activates the balancing board, enabling energy transfer and balance. 2. Inductive energy transfer balance card, featuring current 1.2A energy transfer and battery voltage balancing, significantly equalizes battery voltage and enhances the overall efficiency of the battery pack! 3. By triggering compensation, it corrects voltage discrepancies in the battery pack to an level, reducing maintenance costs. Working Voltage: 2.0V–4.5V. 4. This module performs adjacent voltage difference compensation. When the voltage difference between adjacent batteries exceeds 0.1V, the chip internally initiates compensation until the difference is within 0.03V, then stops. It operates during charging and discharging when neighboring voltage differences exist.
