18650 Battery Pack
An 18650 Battery Pack is a power pack made by combining multiple 18650 lithium-ion cells (each measuring about 18mm in diameter and 65mm in length).
These individual cells are connected in series (to increase voltage) or in parallel (to increase capacity), and integrated with a BMS – Battery Management System for protection and performance management, creating a customized power solution.
At Jetray, our 18650 battery packs are engineered for superior performance and reliability, delivering high-density power for demanding applications including portable electronics, electric tools, medical devices, and energy storage systems. Built from carefully selected 18650 lithium-ion cells and assembled with precision manufacturing standards, they combine exceptional energy density, long cycle life, and consistent output in a compact form.
