3S Active Battery Equalizer 1.2A Precision Active Equalizer Battery Energy Transfer Board 1. 3S Battery Equalizer: The equalizer has 3 serial ports, the working voltage is 2.0V to 4.5V, universal for ternary lithium batteries.2. High Efficiency: The induction battery balance board has a high current of 1.2A, greatly balances the battery voltage and improves the overall battery performance.3. Balance principle: balance starts when the voltage difference between adjacent batteries is greater than 0.1V and stops until the voltage difference is within 0.03V.4. High Accuracy: The equalizer ensures accurate work balance, the battery voltage error will be reversed to the perfect value, reducing the battery maintenance cost.5. Low internal resistance: with improved internal resistance ultra-low MOS, the balance current is from 0A to 1.2A, and the battery voltage difference is smaller. Specification: Item type: active battery equalizer Material: PCB Harness specification: 22AWGTechnical parameter: Operating voltage: 2.0-4.5 V, universal for ternary iron lithium battery, not suitable for LTOR 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 balance current is 1.2Am the smaller the voltage difference, the smaller the equalizing current Wiring definition: B-, the total negative pole of the battery (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 Package list: 1 x Active battery equalizer 1 x cable (random color )Note:1. Due to the working principle of adjacent alignment, it cannot be used as a maintenance tool.2. Need to connect the battery and used together with the lithium battery cover.3. The pressure difference generated by charging and discharging triggers the operation of the equalization plate to realize energy transfer and equalization.
