About this item NOTE: Not recommended to be compatible with low strings, the indicator light will flash and report an error. Before connecting the equalization board, be sure to check whether each battery is wired correctly and ensure proper insulation; otherwise, it may short-circuit and damage the board. If the board is damaged due to short-circuiting, the responsibility rests with the buyer. Thank you for acting with integrity. Applicable battery type: NCM(Li-ion)/LFP, NOT supporting LTO; Single voltage working range: 2.0V-4.5V; Static working current: 0.01mA; Suggested battery capacity: below 30AH. If above 30AH, please choose high-efficiency flying capacitance equalization. Balance method: Detects that the voltage difference between adjacent batteries is greater than 0.1V to trigger the start of equalization, and stops working when the adjacent battery voltage difference is less than 0.03V, entering an under-voltage protection dormant state. Voltage balance accuracy: 30mV (typical
