Features： 1、13S Battery Equalizer: The equalizer has 13 serial ports, the working voltage is 2.0V‑4.5V, and is generally used for ternary iron lithium batteries. 2、High Current: Inductive energy transfer equalization board with high current of 1.2A, significantly balances the battery voltage and improves the overall efficiency of the battery pack. 3、Balance Principle: Balance starts when the voltage difference between adjacent batteries is more than 0.1V, and stops until the voltage difference is within 0.03V. 4、High Precise Equalization: Equalizer provides precise balance work, the battery pack voltage error will be pulled back to an ideal value, reducing battery maintenance costs. 5、Low Internal Resistance MOS: Built in improved ultra low internal resistance MOS, the balance current is 0‑1.2A, and the battery voltage difference is smaller. Specification： Item Type: Battery Active Equalizer Material: PCB Harness Specification: 22AWG Technical Parameter: Working Voltage: 2.0-4.5V, universal for ternary iron lithium battery, not suitable for LTO lithium titanate battery Balance Current: Adjacent voltage difference more than 0.1V, the current is about 0.5-0.7A Adjacent voltage difference more than 0.2V, the maximum equilibrium current is 1.2A The smaller the voltage difference, the smaller the equalizing current Wiring Definition: B-, the total 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 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 B9, the positive pole of the ninth battery B10, the positive pole of the tenth battery B11, the positive pole of the eleventh battery B12, the positive pole of the twelfth battery B13, the positive pole of the thirteenth battery Package List： 1 x Battery Active Equalizer 1 x Cable
