Not really. haven't run any other packs in my mini ste to compare with. I would really like to test the 35c4s3300 packs in my 8s Muggy though. That would be pushing the packs more to their limits. I have 30c Neu packs in there now, and voltage drops to 3.2-3.4v per cell at 30-40c. My 25c pq packs dropped to 2.9v/cell (in the 8s Muggy) at those ratings and they dropped to 3.4v/cell at 18c (in a 8s Slash).
