Tesla 18650 battery cell.

The good thing about 18650 batteries was that these were commodity lithium ion battery cells and allowed tesla to purchase reliable cells from its battery supplier panasonic at the scale it. Each battery cell weighs between 60 to 65g and is 70mm long with a 21mm diameter. Those numbers represent dimensions 18mm x 65mm and 21mm x 70mm respectively. This cell is a lithium ion rechargeable battery with a capacity of 2200 to 3600 mah.

This battery cell is smaller and lighter than the 21700 form factor. The pictured cell appears to be a much larger form factor than the 18650 and 2170 cells used in tesla s vehicles today. Tesla has been using 18650 cells manufactured by panasonic in asia in the models s and x cars since 2013. Model s modules are comprised of 3400mah cells arranged in a 74p6s configuration.

It s the same format of cells found in laptops and some other electronic devices. Panasonic s 18650 battery cell was an industry standard with a proven record of performance that was being produced in large numbers. For a long time tesla has been 18650 cylindrical li ion battery cells in its vehicles. These used 18650 tesla battery modules from a 85kwh model s.

With 41 millimeters in diameter 1 6 inches and 80 mm in length 3 15 inches it s significantly larger than the current 21700 cell used in the model 3 and model y. These are small battery cells slightly larger than the standard aa cells. Yes this thing is massive. 18650 battery these batteries are used in the tesla models x and model s.

They are rated at 500 amps 750 amps peak.
