    In need of 4s 1300 lipo batteries (75c is preferable)

    I am 13 years old and I can't afford to buy any batteries I only have 2 and I would like to have more batteries to fly. It doesn't matter if they are really old and don't work as well as they used to, because flying time is still flying time. EDIT: My email is alotofcatz@gmail.com

    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.
