I don’t think anyone knows how much tesla batteries cost, the article I see floating around simple called up a few distributors of a generic
18650A Battery not a Panasonic 18650A, which is like saying I can get a AA alkaline battery for .10 cents you can but not a Duracell ….
The item is a pair of NCR 18650A Li-ion batteries, which features 3100mAh capacity, and can be recharged and reused again and again. It can act as the power supply for your LED flashlight, LED pointer, electric bicycles and other electronic products, for durable to use. Therefore, it is really a wonderful 18650A rechargeable battery for choice.
