Quality Without Compromise: LG, Samsung & Panasonic Cells
At SPERAS, safety and performance are our top priorities. That is why all our battery cells are imported from industry giants like LG, Samsung, and Panasonic. By utilizing these world-class cores, we guarantee true-to-label capacity, stable discharge rates, and a significantly longer cycle life compared to generic alternatives.
Featured Industry Standards
While our lineup covers all sizes, the 18650 and 21700 formats stand out as the primary power sources for modern professional lighting:
- The 21700 Powerhouse: For maximum runtime and output, the SPERAS 21700 Battery (5000mAh) is the top choice for heavy-duty searchlights and long-range tactical gear. It provides the high-capacity storage needed for extended outdoor use.
- The 18650 Versatility: The SPERAS 18650 Battery (3400mAh) remains the gold standard for everyday carry (EDC) and professional headlamps, offering a perfect balance of weight, size, and reliable performance.
Frequently Asked Questions (FAQ)
Why does SPERAS use LG and Samsung battery cells?
Using cells from LG, Samsung, and Panasonic ensures that our customers receive the highest quality power sources available. These cells are known for their strict quality control, safety, and consistent performance, preventing the capacity-faking and overheating issues common with budget batteries.
Should I choose a 18650 or a 21700 battery?
It depends on your device. 21700 batteries are slightly larger but offer much higher capacity (up to 5000mAh), making them better for high-lumen searchlights. 18650 batteries are more compact and fit a wider range of standard tactical and EDC flashlights. Always check your device's compatibility before purchasing.
What safety features are included in SPERAS batteries?
Our rechargeable lithium batteries feature built-in Protective Circuit Boards (PCB). This technology protects the cell against over-charging, over-discharging, and short-circuiting, ensuring a safe user experience and extending the battery's total lifespan.
