HC01 Battery Equalizer Work for 2 X 24V Battery

What is Battery Equalizer?
Specialized for keep up the voltage balance of batteries connected in series during the Charging and Discharging process, due to differences in the chemical composition and temperature of the battery cell that connected in series,It causes two battery charge and discharge differences even the battery is idle, also due to the different levels of self-discharge could lead to an imbalance between serially connected battery at charging process, because there are differences, it could make a battery excessive charge or discharge,and the other one insufficient charging or discharging.How do Battery equalizer Work?This battery equalizer can compensate both parties when the battery are connected in series as voltage difference exceeds 10 mV, then the battery equalization starts to work, Final achieved balance of the batteries set. It can be connected for long periods for automatically battery state of equilibrium.
