In the beginning, we produced the cylindrical lipoly battery for e-cigarettes. It requests the battery shape be cylindrical and have a longer working time. The other important point is the high discharge current. 18650 battery can meet E-cigarette requests, but the diameter is too big for the E-cigarette. The cylindrical lipoly batteries can be made with smaller diameters, higher capacity, and higher discharge current. We have made more than 100 batteries with diameters and heights from many E-cigarette manufacturers for their different shapes of products. After that, we also found other applications for these batteries, such as electric toothbrushes, wireless speakers, wireless headsets… 

Cylindrical LiPoly batteries have carved a niche in the energy storage landscape due to their distinctive design and performance features. Here’s a look at why they stand out:

Optimized Energy Density: Their cylindrical form factor allows these batteries to pack more power into a smaller footprint, providing higher energy density compared to traditional rectangular LiPoly batteries.

Robust Design: The cylindrical shape adds mechanical stability and reduces the risk of damage from impact or vibration, making them ideal for rugged applications and portable devices.

Efficient Thermal Management: Their geometry offers better heat dissipation, reducing the likelihood of overheating and improving safety, especially in high-drain applications.

Versatile Integration: Cylindrical LiPoly batteries can be more easily stacked and arranged in series or parallel configurations, enabling diverse design possibilities across various applications.

High Power Output: Their internal structure allows for high discharge rates, ensuring consistent performance for devices that require significant power surges.

Longevity: With proper care, these batteries offer an extended life cycle due to advanced materials and protective features, making them cost-effective over time.

Customizability: Manufacturers often offer cylindrical LiPoly batteries in a wide range of sizes and capacities, making them suitable for everything from wearable devices to industrial machinery.

Our cylindrical lipoly batteries have a rich inventory, different sizes, and capacities, and they are a good choice for electronic cigarette applications or other column devices. These cylindrical lipoly batteries have a long storage time and an excellent expected cycle life: 500 cycles≥ 80%. We accept small sample orders and bulk production for cylindrical lipoly batteries, which is very friendly for start-up companies.
