It looked really simple with just two short rows of tiny buttons. What? But it is just that , if you believe. I got this instead of the bigger one, as my largest LiPos are 4-cell ones. Just plug in the battery, push the "Current" button until the tiny light for the amount closest to the battery rating is lit, push the "Cells" button until the tiny light by the correct number is lit. if wrong, it will stop. Then itgoes to work. The "Status" light blinks and soon it stops when your battery is at "Storage" voltage.
I like it!
