The basis of the early Tesla products are lithium-ion cells in the 18650 form factor.
These cylindrical cells have a diameter of 18 mm and are 65 mm in length, a size used for the batteries of laptops.
Cylindrical cells are generally less expensive (costing 190–200 dollars per kWh as of 2014) than large format cells whose active layers are stacked or folded (approximately 240–250 dollars per kWh).
They are used in Model S and X, and Powerwall 1.

In October 2015, Tesla moved the Tesla Powerwall and Powerpack production from its Fremont factory to the Gigafactory.
The Tesla Powerwall has been produced in the finished portion since the third quarter of 2015.

2170-cells are transferred on autonomous vehicles from Panasonic to Tesla, where workers and robots assemble cells into packs using bandoliers, cooled by tubes made onsite by Valeo.

Drive units (motor and gearbox) for Model 3 are made with 90% automation.
