I have a large collection of these batteries that I use in all sorts of RC vehicles, and projects.  Fantastic discharge rate and none of the 10 batteries I have in use are puffing.  Excellent quality, for your Traxxas xmaxx, udr, arrma, losi, 1/5th, 1/7th, 1/8th, 1/10th scale rc trucks, boats, airplanes, crawlers, or even use as backup power banks using ec5 to usb convertors to make your own power banks, or connect in series or parallel to make high quality packs for things like ebikes, carts, that are totally modular. Feel free to message me with any questions or requests.
