6 FAQs about Inverters & Power System Solutions

Will 21700 cells replace 18650 cells?

This makes 21700 cells ideal for high-current applications like devices like power tools and electric vehicles. While it is true that 18650 cells are still being manufactured, we will more than likely see 21700 replace them as the industry standard for everything but the most compact portable electronics.

Are 18650 batteries the same as 21700 batteries?

No. 18650 batteries have that name because they are 18mm wide and 65mm tall. The trailing 0 simply means it's a cylindrical cell. 21700 batteries, on the other hand, are 21mm wide and 70mm tall. This is why 21700 cells cannot fit in the same space that a 18650 can, but a 18650 can fit in the same place as a 21700 can.

Why are 21700 battery cells so popular?

21700 battery cells are gaining popularity quickly. 21700 battery cells offer more power and more often than not provide more current than 18650 battery cells. This makes 21700 cells ideal for high-current applications like devices like power tools and electric vehicles.

Why might an 18650 charger not fit a 21700 battery?

Most 18650 chargers are not designed to charge 21700 batteries directly. The 21700 battery has a larger diameter, which may not fit properly in an 18650 charger. Additionally, the charging current and voltage requirements of 21700 batteries may differ from those of 18650 batteries.

Are 18650 batteries good for power tools?

Batteries that we see using 18650 cells for power tools range from 1.5Ah (1500mAh) to 3.0Ah (3000mAh) in each cell. 18650 cells on the higher end of that scale have reported issues, and 2.5Ah (2500 mAh) cells seem to be where most manufacturers settle at the top.

Why do 21700 cells have higher currents than 18650 cells?

Also, 21700 cells can support very high currents, most of their 18650 counterparts. A 21700 cell can output higher currents due to its often lower internal resistance levels. These three factors are again attributed to the size difference between the cells.
