Heltec BMS 4-6S Capacitance Active Balancer for Car Audio Lithium Batteries This Listing Includes: (1) Capacitance Active Balancer Features: - Working voltage: 1.8V-4.5V - Suitable for ternary lithium, lithium iron phosphate, lithium titanate. - The whole battery participates in the active equalization of energy transfer at the same time - 0.1V differential voltage 1A equalizing current. The differential voltage is bigger than equalizing current is bigger. The maximum allowable working current is 5.5A - Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB - Equilibrium current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv! - The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH. - With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA
