Jaycar Samsung High-Drain 18650 Li-Ion Battery – 3.7V 2500mAh 20A

Your flashlight, e-bike controller, or power tool cuts out the moment you push it past a light load. That's a cell that can't handle the draw. This Jaycar Samsung 18650 is rated for 20A continuous discharge — 2500mAh at 3.7V — so it holds its voltage when you actually need power, not just on paper. High-drain cells like this are what separate a tool that finishes the job from one that dies halfway through. Drop it into any standard 18650 slot, charge it, and get back to work.
