Hyperion 7i Wiring

A little more data on the 7i:

When maxed out to 120w output, the 7i draws 151 watts. The extra power (31w) is simply dissipated as heat on the heatsink.

I charged a 14 cell NiMH pack I have at 7A (or tried to), and easily hit the 120w mark. Once there, the pack voltage slowly increased, but the charge current steadily decreased to meet the 120w limit. Actually, the 7i was outputting 121w, but close enough. I measured the current on the input at 12.5A with a supply voltage of 12.07v.

So, it looks like you need a minimum of a 150w power supply to run the 7i to its max rating. Personally, I'd choose a 170w-200w supply because it's never good to run things to their max ratings.
