Do you find when you charge at these levels that it only takes the several minutes, but then it spends a few times that just balancing? Will these cells typically take that high of amperage and stay relatively balanced so that it's not having to rely on the tiny balancing port to balance them out? In other words if I have a pack that can charge within 5 mins, is it going to spend another 15 mins just balancing out? What's a realistic charge time for say a 5,000 mah pack when charging it from say a typical lipo cutoff voltage to a "full" (balanced) charge?
