Inductive energy transfer balance board, high current 1.2A energy transfer battery voltage balancer, significantly balance the battery voltage and improve the overall efficiency of the battery pack Please note: The appearance and color of different batches of products may vary, which does not affect the useBalance Instructions:1. When the equalization light is on, the equalization work is turned on,2. The equalization light is off, the equalization circuit is in sleep state,3. The equalization light flashes, indicating that the string is dropped, or the circuit is faulty.Equilibrium principle:This module is the balance of adjacent voltage difference, the voltage difference between adjacent batteries reaches 0.1V or more, and the chip will trigger the balance work, until the voltage difference between adjacent batteries is within 0.03V and stop working.When it is used on the battery pack, there is adjacent voltage difference when charging and discharging. Triggering the equalization work, the battery pack voltage error will also be pulled back to an perfect value, reducing battery maintenance costs.technical parameter: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 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, the positive pole of the second batteryB3......and so on.Colour:blackMaterial:PC+MetalSize:40 x 23mmPackage Contents:1 x Active Equalizer Balancer1 x CableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
