For less than $30, you cannot beat this battery. Cheap, but good. These are good basher packs. I have been running 3 of them for 1 year and a half, and while they have clearly shown signs of wear and tear, they still work as perfectly good basher packs. Yes, they have lost punch, but the cells have not lost capacity, nor are the cells off-balance. No puffing of any sort on any of the packs. Just be aware, they are pretty long. They will not fit in a stock Stampede 2wd or Rustler 2wd battery tray without some modifications. Good job Value Hobby.
