Traxxas 3000Mah 11.1V 3-Cell 20C Lipo Battery W/ Id Plug 3s - 2830X - This is a used battery of unknown age. It is either a customer return or pre-owned, and has been sitting for quite a while on the shelf. It has been tested to make sure the cells are balanced, and that it charges on a Traxxas iD charger. Please do not expect that it will look or function as good as a new battery; it is a used discount battery.
