Zeee 2S 7.4V 5200mah Lipo Battery for RC dual bump nitro starter box super cheap on Amazon

I needed some new inexpensive lithium Polymer batteries for my bump box. The bump box is just for starting Nitro RC cars. I don't really care about quality because its not powering an electric RC car. I've had these for a month and so far so good. I happy LiPo batteries are going down in price.
