I got thinking about this post when I stumbled across this while using a Velosity on my VT133 with 2 25r's. Here is the live view of it firing at 90 watts with 1 second 110 watt preheat and 11 punch. I've upped the temp to keep it out of the way. So I move the atty to my VTBox200 with lipo, same settings. I'm looking at the green line, temp at this point is null. When I get home from work I'm going to replace the two 25r's in the VT133 with some LG HD2's that I got yesterday and check it again. OK, got home and put in two never used just off the charger LG HD2's....It was my not very old Samsung 25r's was the problem (maybe fakes, who knows but I doubt it) Here is my live view on the VT133 with new batteries. Looks better than with the lipo. Sorry BL, I didn't think it would turn out this way.....LOL
