Everette,

The black negative wire from your pack goes to the black terminal on the top of the charger. The red positive wire from your pack goes to the red terminal on the top of the charger. The two center terminals aren't used in the 10S configuration. On the side of your charger, there are two balance tap connectors labelled "Ch 1" and "CH 2". How you use those will depend on how you're hooking up your balance taps. If you use the balance boards that Revelectrix sells, you'll need a balance board for each channel. The balance board plugged into CH 1 will connect to the balance tap closest to the black wire from your pack. You'll use the 5S connector on the board. The board connected to the Ch 2 gets the balance tap closest to the red wire on your pack and you'll use the 5S connector on that board. The charger will internally treat it as two, 5S packs in series which it actually is.

Before you do any of that, you'll need to program the charger to accept a 10S pack as well as the charge rate you plan to charge at.

The hookup for all of this is the same as it was with the CellPro 10S. I charge this way all the time even though I use 5S packs and just hook them up in series. The easiest way to remember it is black always goes with Ch1 and red always goes with Ch 2. Once you hook it up a few times, it'll be second nature.

Hope this helps!
