Built-in extremely low internal resistance: built-in upgraded MOS with extremely low internal resistance, compensating current from 0 to 1.2A, achieving lower battery voltage difference. 【Note】: 1. The adjacent compensation works and cannot be used as a maintenance tool. 2. To connect the battery, use it together with the lithium battery protector. 3. The voltage difference generated by charging and discharging triggers the work of the balancing plate to achieve energy transmission compensation. Low power consumption: the smaller the voltage difference, the smaller the balance current and the static current consumption does not exceed 20μA, which saves energy. Protect battery: A voltage error of the battery pack also triggers the balance board which is reset to an ideal value, reducing battery maintenance costs. Working principle: this module compensates for adjacent voltage differences. When the voltage difference between adjacent batteries reaches more than 0.1V, the chip triggers the compensation work and stops working until the voltage difference between adjacent batteries is within 0.03V. › See more product details; Product description Specification: Item Type: Battery Balancer Material: PCB. Wiring harness specification: 22AWG Technical parameters: The working voltage is 2.0V-4.5V.The ternary iron lithium battery is common and the LTO lithium titanate battery is not suitable. Balance current: The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A); The adjacent voltage difference is more than 0.2V (the maximum equilibrium current is 1.2A); The smaller the voltage difference, the smaller the balance current. Wiring definition: B - the entire negative pole of the battery pack (the negative pole of the first battery). B1, the positive pole of the first battery. B2, the positive pole of the second battery. B3, the positive pole of the third battery. B4, the positive pole of the fourth battery. B5, the positive pole of the fifth battery. B6, the positive pole of the sixth battery. B7, the positive pole of the seventh battery. B8, the positive pole of the eighth battery. Use: Balance Instructions: 1. When the balance light is on, the balancing work is on, 2. The balance light is off, the balance circuit is in idle state, 3. The balance light flashes indicating that the string has fallen off. or the circuit is faulty. Package list: 1 x battery balancer. 1 x cable. Note: 1. Adjacent compensation works and cannot be used as a maintenance tool.2. To connect to the battery, use it together with the lithium battery protector. 3.
