I have this one and it works great and it balance charges your lipos. all you do is plug it the battery into the charger using the balance plug on your battery and it charges. it stops charging when the battery is fully charged so it wont get ruined if you leave it on there too long. it also displays the batterys total voltage and voltage of each cell and the lights light up green when its done charging. it charges 7.4v lipos and 11.1v lipos it also charges li-mn batterys too. hope this helps
