I've been running with turnigy lipo cells for almost three years now.

2*2s 5000 20C (oldest ones, they're retired now, but they did about 200 cycles in my 2wd slash)
1*3s 5800 20C (one cell was bad at arrival, but I was able to get it working with some chargertrickery (not recommended) and it lived for about 100 cycles after that)
2*2s 5000 25C (hard cases, no problems, I'm still using them. about 100 cycles)
2* 2s 5800 25C (soft cases, no problems still using them)
2* 2s 6000 nanotech 25 C (soft cases, still using them)
2* 4s 4000 nanotech 45C (soft cases, still using them)

Except for the bad cell in the 3s pack i haven't had any problems with balancing or uneven discharges.

To roar or not to roar does often seem to stir up quite alot of feelings, and I'm not going into that question, just stating my experience with turnigy lipo cells.
