Great charger but mine has developed a problem. Channel 1 gives a "Output Voltage Too High" warning when attempting to charge any battery (channel 2 works fine). Has anyone else gotten this warning? How did you cure it?
Is there a repair center for Hyperion?

Try swapping the balance board and see if the problem follows the board. I've also heard updating the firmware may help this problem. Please post back if you fix it.

Is the balance board one of the two smaller boards inside?
Found the updates, and have ordered the adapter/cables (HP-TI-PRGUSB and HP-EOS06-PCCBL) from Air Craft RC in Japan.

Just curious, but you know you can get Hyperion accessories from some one like All E RC here in the US - you'll have it sooner than coming from Japan.

You can get some phone support from them as well.

The balance boards are the small board that the lipo balance connector plugs into. These are connected to the charger. Advice was to see if the prob you're having was the balance board or in the particular charger port.

AllERC is the company that the charger was purchased from, so they were checked first. They did not have both cables, (one listed as discontinued). Don't use balance boards as the charging cables we made by Hyperion for the bullet plug lipos that I use.(took me awhile to figure that out). Will contact them for support on Monday (thanks).
