It is known for its large capacity and high current output, making it an ideal power source for high-drain electronic devices such as electric vehicles, power tools, and portable electronics. The 21700 designation refers to the cell''s dimensions: approximately 21mm in diameter and 70mm in length.
The 21700 LI battery cell does not have a pin configuration as it is a cylindrical cell with a positive and negative terminal. The raised terminal on the top of the cell, typically marked with a "+" sign. The flat terminal on the bottom of the cell.
For this article we will concentrate on the 21700 format, but this is migrating towards the 46mm diameter 46xx class of cylindrical cells in a push to reduce cell manufacturing costs. The 21700 cell increased the working volume over the 18650 by a factor of >1.4x
The flat terminal on the bottom of the cell. Battery Holder: Use a 21700-compatible battery holder or a custom battery pack to securely hold the battery cells. Proper Orientation: Ensure the positive and negative terminals are correctly aligned with the corresponding connections in your device or battery management system (BMS).
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
For this article we will concentrate on the 21700 format, this is migrating to the 46mm diameter cylindrical cells to reduce pack costs.
