What should I consider when purchasing 21700 batteries?

Capacity: Measured in milliampere-hours (mAh), the capacity indicates how much energy the cell can store. Higher capacity cells generally provide longer runtime.
Discharge Rate: Expressed in amperes (A), the discharge rate influences the cell’s ability to deliver power quickly. Higher discharge rates are essential for applications with high power demands.
Type: Standard 21700 batteries or cells have a ‘flat top’. However, some variants may have a button top, which looks like the positive top of a ‘normal battery’ like this ‘πŸ”‹’.
