Note: If the battery is connected, it must be used with the BMS protection board. The charge/discharge voltage difference triggers the balance board to work to achieve energy transfer balance. Applicable battery: NCM(Li-ion)/LFP, NOT Fit LTO. Single battery voltage: 3.0-4.2V Suggested battery capacity: below 30AH, If more than 30AH, pls search B096NLHXPF . Voltage balance accuracy: 30mV (typical value) between adjacent voltages Balance method: Detect that the voltage difference between adjacent batteries is greater than 0.1V to trigger the start of equalization, and the adjacent battery voltage difference is less than 0.03V to stop working. Balance current: 0.1V voltage difference 0.5A balance current, the maximum balance current is 1.2A when the voltage difference is above 0.2V. Under-voltage protection dormant voltage: The adjacent voltage difference is less than 0.03V and enters dormant state. Static working current: 0.01mA Accessories: 30cm 22awg terminal wire Product Size: 3.34x1.77x0.25inch Balance indication: 1. When the balance indicator on, the balance work is turned on. 2. The balance indicator OFF, the balance circuit sleeps, 3. The balance indicator flashes, it drop cells, or the circuit is faulty. Note: The cable plug needs to be inserted obliquely, first touch the B- pin and insert it obliquely, otherwise it may cause the board to burn out!
