Ran my IB4200 pack today for the first time, charged it up at a more "gentle" 4a charge and ran it in my T2 with Orion Method R 19x2.......very nice run. Despite this only being the first charge run through it (dumped it previous to charging, but that doesn't count), I got a solid 15 minutes of runtime before they started to show signs of dumping, I was actually very glad by the time it started slowing because it was a bit cold outside tonight........45* is cold for us at least.

Anyway, first run, went great, solid power, good punch, and super long runtime.........I'm hoping the pack doesn't blow up or anything because I like it thus far. :)
