Description 1. Inductive energy transfer balance board, current 1.2A energy transfer battery voltage balancer, significantly balances the battery voltage and improves the overall efficiency of the battery pack! 2. Please note: The appearance and color of different batches of products may vary, which does not affect the use. 3. Equilibrium Principle: This module compensates for adjacent voltage differences. When the voltage difference between adjacent batteries reaches 0.1V or more, the chip triggers the balancing function until the voltage difference is within 0.03V, then stops working. 4. Balance Instructions: When the compensation light is on, the compensation function is active. When the compensation light is off, the balance circuit is in sleep mode. If the balance light flashes, it indicates a disconnected string or broken circuit.
