E-Fatbike with "Tesla cells"

At Astonic, we have equipped our E-Fatbike batteries with advanced 21700 cells from Samsung or LG, commonly referred to as 'Tesla' cells. But what sets these cells apart from the 18650 cells by Samsung or LG? In this article, we'll delve into the differences.

The primary distinction between lithium 18650 and 21700 batteries lies in their size and capacity. A 21700 battery is larger and has a higher capacity than an 18650 battery.

A lithium 18650 battery measures 18 millimeters in diameter and 65 millimeters in length, whereas a 21700 battery is 21 millimeters in diameter and 70 millimeters in length. This size difference allows a 21700 battery to accommodate more active material, resulting in a higher capacity.

In general, 21700 batteries exhibit greater capacity and superior performance compared to 18650 batteries. They can store more energy and have a longer lifespan than their 18650 counterparts. These batteries find applications in energy-demanding scenarios, such as electric vehicles and energy storage systems.

While 21700 batteries tend to be more expensive and offer fewer options due to their relatively shorter time in the market compared to 18650 batteries, for us, the choice of these cells was a no-brainer. Quality is far more critical than cost-cutting considerations.

 E-Fatbike batteries with more power and range: Because honestly, the range of your battery can never be too extensive! At Astonic, it's even possible to install two batteries on your bike, with an inverter ensuring simultaneous energy extraction from both batteries. Consequently, many Astonic E-Fatbikes on the road boast a capacity of 40Ah or 1920 kW. If that doesn't entice people to leave their cars behind...

Larger size, more capacity! The increased size of the cells results in higher capacity, up to 4.8Ah. This extension enhances the battery's lifespan from the typical 500 charging cycles to an impressive 1,500 to 2,000 cycles.

These potential 2,000 charging cycles lay the foundation for a significantly prolonged lifespan of E-bike batteries.
