You have to set up both channel 1 + 2 for the proper setups, press and hold enter and it will say solo and then I beleive you press up or down to select sync. Then hold enter to start charging. I have used it to sync charge 2 3s packs and it worked flawlessly. I will say that the Hyperion chargers are great but their instruction manuals suck! I read my manual through and had a hard time getting it set up to do anything! Next time I just played around with it and it and now I understand how it works much better
