Feature: Lithium battery active balance energy transfer board Lithium battery active equalizer High efficiency energy transfer equalization Inductive energy transfer equalization board (current 1.5A equalization current, slightly lower precision) Technical Parameters : Working voltage 2.2V-4.5V, Li-ion Lipo Lifepo4 LTO Lithium battery universal Working principle, the inductor converts the transfer charge carrier. When the battery error voltage is above 0.1V, the balance work is started until the error is stopped at 30mv. The built-in improved ultra-low internal resistance MOS, the balance current is 0-1.2A, and the battery voltage difference is smaller. The smaller the current, the static power consumption does not exceed 20uA! With balance instructions! Balanced voltage accuracy within 30mv! Wiring line length 30cm pure copper 22awg terminal wire! High-precision energy transfer balance, exclusive balanced IC! Balance indication: 1. When the balance indicator is on, the balance work is turned on. 2. The balance indicator goes out, the balance circuit sleeps, 3. The balance indicator flashes, it drop cells, or the circuit is faulty.
