Tesla has revealed the Cybertruck's battery featuring 1,344 individual battery cells with a combined capacity of 123 kWh

Tesla has been secretive about the details of its battery technology for many years, and even the specific battery capacity of its models is not listed on its website. However, in the 2023 Impact Report on page 109, Tesla has revealed the "battery passport" for the Cybertruck.

Tesla has revealed the detailed "battery passport" for the Cybertruck, providing official information about the 4680-type cylindrical cells and the structural battery pack used in the vehicle. This information corroborates some of the unofficial details previously obtained through teardowns, while also revealing new details.The Cybertruck's battery pack uses Nickel-Cobalt-Manganese (NCM) lithium-ion chemistry, consistent with the findings from the Limiting Factor teardown in mid-2022. Each individual cell has a capacity of approximately 91.5 Wh, and the total pack consists of 1,344 cells, resulting in a combined capacity of 123 kWh.The battery pack weighs nearly 1,600 lbs (721 kg), accounting for around 24% of the Cybertruck's total weight (6,603 lbs or 3,000 kg for the AWD version). While the structural integration of the battery helps offset some of the weight, the overall pack is still quite heavy. The energy density is around 0.17 kWh/kg, which, while not poor, still leaves room for improvement.The details revealed in the Cybertruck's "battery passport" are significant, as the 4680 cells represent the next generation of battery format that is being developed by Tesla and will soon be produced by other suppliers for use in other automakers' vehicles.

The key details revealed in the Cybertruck's "battery passport" are:

• Battery chemistry: Nickel-Cobalt-Manganese (NCM) lithium-ion cathode

• Battery form factor: 4680-type cylindrical cells (46 mm diameter, 80 mm height)

• Number of battery cells: 1,344

• Total battery pack capacity: 123 kWh

• Individual cell capacity: ~91.5 Wh

• System voltage: 800V class

• Battery weight: 1,589.5 lbs (721 kg)

• Energy density: ~0.17 kWh/kg (170 Wh/kg)

• Estimated driving range: 340 miles (AWD), 320 miles (Cyberbeast)

The report also reveals that Tesla plans to offer a range extender option for the Cybertruck AWD and Cyberbeast versions later this year, which is expected to increase the range by around 38% to over 470 miles and 440 miles, respectively, by adding about 47 kWh of additional capacity for a total of around 170 kWh. In 2025, Tesla also intends to launch an entry-level rear-wheel-drive (RWD) Cybertruck version with a smaller battery pack and a range of roughly 250 miles. The 4680 cells used in the Cybertruck are about 10% more energy-dense than the initial cells used in some early Tesla Model Y versions, indicating the potential for further improvements as this new cell format matures.
