3S 4S 5A BMS Active Balancer Board Li-ion Lifepo4 LTO Battery Capacitor Equalizer Power Transfer with Protective Case

Specifications Model 3S 4SApplicable lithium iron phosphate NCM ternary polymer lithium titanateVoltage is 1 8V 4 5VQuiescent current 12mARecommended battery capacity 35 300AHWorking temperature 0 60 degrees Capacitor principle No external power supply is required The working principle is that the capacitor is adapted to transmit the charge transmitter and the entire battery pack is transmitted and balanced by using the internal energy transmission of the battery Start balancing work Port Description 1 B B1 B2 B3 B4 are the nodes of each battery 2 The two pads marked EN RUN on the board are short circuited by default so that the balance board enters the balance when it is powered on In the working state you can also disconnect the back lead and switch to control the balanced work Generally there is no need to connect the switch With automatic sleep function non professional personnel should not connect the switch to avoid damage 3 The indicator light of EN RUN is to indicate the continuous working state of the balance and it will go out only if the battery is under voltage protection or the balance board is faulty 4 The se1quence of the 4 string equalizer board is generally from B →B1→B2→B3→B4 from the low string to the high string one by one 5 The line se1quence of the 3 string equalizer board is generally from B →B1→B2→B3 from the low string to the high string one by one and B4 is empty Protection switch With sleep protection
