Lithium-Ion Battery
Upgrade to the power of Lithium-Ion technology. These rechargeable cells offer the highest energy density available, providing long runtimes and hundreds of charge cycles. Whether you are powering a high-drain flashlight or building a custom battery pack, our Li-ion cells deliver consistent, high-capacity performance.
Available Sizes & Voltages
Unlike standard household batteries, Lithium-Ion cells typically have a nominal voltage of 3.6V to 3.7V (reaching 4.2V when fully charged).
| Size | Nominal Voltage | Characteristics |
| 18650 | 3.6V/3.7V | The industry standard; versatile and widely available. |
| 21700 | 3.6V/3.7V | Larger capacity, used in modern high-power devices. |
| 14500 | 3.6V/3.7V | Same dimensions as a AA, but much higher voltage. |
| 16340 (RCR123A) | 3.6V/3.7V | Compact size, often used in tactical gear. |
Common Usage
Lithium-ion batteries are designed for high-drain devices that require frequent recharging:
- Professional Lighting: Tactical flashlights and LED work lights.
- Portable Electronics: Power banks, laptops, and high-end cameras.
- Personal Care: Electric shavers, toothbrushes, and hair clippers.
- Vaping & Hobby: Electronic cigarettes and RC (remote control) vehicles.
- Mobility: Electric bikes, scooters, and cordless power tools.
