Tesla 18650 Battery Cell

For a long time tesla has been 18650 cylindrical li ion battery cells in its vehicles.

Tesla 18650 battery cell.

Panasonic s 18650 battery cell was an industry standard with a proven record of performance that was being produced in large numbers. This battery cell is smaller and lighter than the 21700 form factor. The tesla cylindrical cells are 18 mm in diameter and 65 mm tall. Model s modules are comprised of 3400mah cells arranged in a 74p6s configuration.

18650 battery these batteries are used in the tesla models x and model s. These are small battery cells slightly larger than the standard aa cells. This cell is a lithium ion rechargeable battery with a capacity of 2200 to 3600 mah. 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.

Yes this thing is massive. These are currently the best battery on the market for energy density allowing many classic conversions to get well over 200 miles per charge. Each battery cell weighs between 60 to 65g and is 70mm long with a 21mm diameter. 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.
