Of course the cycle was done as normal 4amp or 4000mah rate. 35amp discharge with 180 second cool down. Blah blah blah...

I'll cycle again tomorrow night and Pack 1 IR should drop back to normal. But I'm curious as to what Pack 2 will do. I do notice run time slowing going down. But that might be due to me charging at 12 amps. I'm gonna go to 8amp charge for racing and see what happens. Plus now I'm starting to heat up my packs after charging. Of course all my cycles are 1C at 4000mAh or 4amps. 35amp discharge with 180seconds cool down for the cycle. Packs are discharged down to 6v before cycle starts. Here's the history so far. Each packs usually get 3 runs on race day. 1~2 cycles during the week. So about 4 or 5 charges a week for each pack.
