    Educated Guess on Quality of batteries?

    I have a 3s 2200mah 30a discharge lipo and a 2s 1750mah 25a lipo for my quad and 2 planes. These are the only two batteries I've ever had, as I'm not that deeply involved in the RC hobby. I haven't used them in a year because I don't have a liscence yet and biking to the nearest field with an FT...

    Puffed Lipo?

    Hey, does anyone here know if the battery on the left is swollen/puffed? When I press it it goes down a little. I've seen more extreme examples of swollen lipos but wasn't sure if this was swollen.

    Motor Stutter

    I'm running an emax rs2205 2600kv motor with a 40a ESC on a 3S lipo and 5x4 props, and I'm getting issues with the motor stuttering on low throttle. I tried a 12a and an 18a ESC and had the same issue. Is my battery too low voltage or is my ESC too low amperage for the rs2205?
