With the Battery Balancer demo web-app you can demonstrate on your phone or tablet how the battery balancer works. There are two sliders on each side of the screen. With these sliders you can create an out of balance battery system. As soon as you release the slider, the balancer will then operate based on the specifications in the data-sheet. The onscreen LEDs and energy flow will react accordingly.
