Strange battery behavior!
 

Hey guys~

One of my 4s 5000mAh packs is acting funny. It charges just fine and reads perfect when tested. The problem is that the battery has NO punch when I run. I am thoroughly confused for my Hyperion charger does not alert me of any issues either. Any help would be greatly appreciated, thanks!

Could you be a bit more clear as to what you mean by "No Punch" I'm sorry but that doesn't tell me what it's doing or not doing compared to another pack.
