Key Features of 18650 Li-ion Battery:

High Capacity Range

Available in capacities from 1800mAh to over 3500mAh (and even higher in specialized models), balancing power output and runtime for diverse needs.

Requires Protection Circuit

Needs a protective circuit module (PCM) to prevent overcharging, over-discharging, and short circuits, ensuring safety and longevity (a trade-off for their high energy density).

Good High-Temperature Performance

Operates efficiently in moderate to high temperatures (up to ~60°C), though extreme heat can degrade lifespan (Ni-MH performs better in sub-zero conditions but worse in heat).
