When I get back from Florida, I'll have to take pics of how I ran mine. I split it to two hoses. One thing I will warn you about, batteries don't last long in the winter. Think 30 min. In warmer weather, you can change out batteries at lunch.
I have not run rechargeable batteries, but I can't recall if I've run lithium or not. I've gone through about 3 sets of batteries in it, and I don't recall what I used in it. I've been contemplating just making a battery pack for it. Put some Lipo's in it and call it a day. It will likely need a regulator (DC-DC converter) to get the voltage right, but it would eliminate having to ever change batteries mid-day.
I use the same unit, and it is the only anti-fog system I have gotten to work so far. I tried Revision turbofans, which were pretty much useless. I run it on a helmet, and just run the tube in the side of my goggles. I talked to the guys who make it in NC at Fulda Gap, and they claim that Rayovac batteries will give you four or five hours between changes. My only complaint is that the fan is pretty loud; there are plenty of fans like it that vibrate and whine a lot less.
