Goodhd 4S 1.2A balance lithium battery active equalizer balancer energy transfer BMS

Note: This board is based on the principle of adjacent equalization and cannot be used as a maintenance tool. To connect to the battery it must be used together with lithium battery protection. The voltage difference generated by charging and discharging triggers the work of the equalization board to achieve energy transfer and balance. Micro Lithium Battery Active Balance Energy Transfer Board Lithium Battery Active Balancer Rate Energy Transfer Balance 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! Balance 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 ideal value reducing battery maintenance costs. Technical parameter: Working voltage: 2.0V-4.5V ternary iron lithium battery is common 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 (to reach the equilibrium current of 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 battery) B1 the positive pole of the battery B2 the positive pole of the second battery B3......and so on. Accessories: Wiring line length 30cm pure copper 22awg terminal line! High-precision energy transfer equalization balanced IC! The four-string wiring diagram is as follows and the other strings are analogous! Note (The cable plugs with more than 13 strings need to be inserted obliquely first contact the B-pin and insert them obliquely upward otherwise it may cause the board to burn out) Packing list: 1*Cell Balance Module
