Product FAQ

Custom 18650 Battery Pack

When should an OEM pack use 18650 instead of 21700 cells?

18650 is often useful when the project needs mature sourcing, smaller diameter constraints, existing mechanical compatibility, or lower initial sampling risk. Final selection should compare current, runtime, space, certification target, and annual volume.
