Technical FAQs 4

How many cells are in a single 21700 battery?

A single 21700 battery contains 4416 cells, as seen in the Model 3/Y Long-Range battery pack. The battery pack consists of 4 modules, with each module containing 46 cells.

What is 21700 battery?

21700 battery is one of the most popular and commonly found cells in the battery pack in electric vehicles, battery-powered construction equipment, portable power cutting/ drilling tools, the emergency torch, flashlight, etc. after 18650 battery cells.

What are the characteristics of a 21700 battery?

The characteristics of a 21700 battery include a capacity in the range of 3000 to 5000 mAh, depending on the model, design, and chemistry. The charging and discharging currents of 21700 batteries depend on the high or low-drain power of the battery.

Are all 21700 cells the same?

Not all 21700 cells are built the same. Some are optimized for high capacity (great for long runtime), while others are tuned for high discharge rates (better for power-hungry tools or drones). There’s a fun discussion I came across where hobbyists compared popular options.
