Heltec 4-6S Capacitance Active Balancer for Car Audio Lithium Batteries
(1) Capacitance Active Balancer Features: - Working voltage: 1.8V-4.5V - Suitable for ternary lithium, lithium iron phosphate, lithium titanate.
 
Comes with a user manual.
 
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 the 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
