The most popular Tesla battery pack contains 7,104 18650 cells in 16 444 cell modules. The entailed capacity by the 18650 batteries stands at 85 kWh of energy.

Can I use AA in place of 18650?

Can I Use AA Battery Instead Of 18650? If a device is asking for a li-ion 18650 batter then it is expecting somewhere between 3 to 4.5 Volts to run. AA batteries run between 1.2 to 1.5 Volts. So, unless the device specifically says that it can run off of both power sources it will not be possible.
