Why are 18650 cells better than AA batteries?

For starters, 18650 cells have a higher voltage than AA cells. This means that it takes less 18650 cells in series to produce a voltage suitable for consumer electronics. Also, 18650 cells have far lower ISR (internal series resistance) than a AA battery. This makes it so less 18650 cells are required to achieve a given current carrying capacity.

Spot Welding Vs Soldering Lithium Cells

It takes a high degree of skill to solder lithium cells. It''s not something that can easily be learned on the spot so that you can build a battery pack with 18650 cells. Soldering lithium cells requires a type of soldering that takes great skill to master. Spot welding, on the other hand, can be learned relatively quickly.

Which 18650 batteries should I buy?

If you are in the market for new cells, I recommend the following brands 18650 cells from Panasonic, Samsung, Sanyo, LG, and Molicel. These 18650 brands have good track records and you can trust their datasheets and ratings. Most of the time, 18650 cells from these brands will cost more, but they are a battery value for the money.
