Best 18650 Battery Explanation!

“Batteries are very, much like tires…buy what you need”


PVA has been putting out educational series videos for over 4 years now and it has always been amazed that when looking back how much of our teachings we have revised throughout the years.  We’re sure you’ve heard of many comparisons of energy to water or traffic, but after all the arguments we’ve heard, they still don’t apply much to helping folks pick out the battery that is best for them.

Batteries are easier to understand than we think.  Batteries are very much like tires in the sense of how to select and purchase them for our needs.
Tires have two main ratings, batteries have two main ratings.  The relationship between the specs is very similar.

The specs on tires are:

  • The speed it is rated for.  = How fast can the tires spin or how much speed can the tire handle.
  • The tire tread it is rated for. = How long does the tire last before it needs changing.

So let us compare this to batteries and how similar they are.

The specs on batteries are:

  • The amperage it is rated for. = How much current the battery can handle.
  • The Milliamp hours it is rated for = How long does the battery last before it needs changing.

This will help you understand exactly why we have different battery ratings and why you would select one over another.  Folks seem to have a misconception of how a battery rated for higher amps will hit harder.
This is simply not true.  It would be the equivalent of saying how racing tires will make the car faster.   Of course, race tires are essential to any racing setup, but its function is to allow for more potential rather than add any base power.  The same can be said for batteries.  Higher drain batteries in this sense are the same as having higher rated amp fuses.   These ratings are here to support more power, not to produce more power.

Therefore if you’re not looking to race around there is no reason to use race tires on your vehicle even if it is a sports car.  Using tires of a higher speed rating for a moderate commute will not increase the safety of your vehicle, and neither will using higher drain batteries for moderate wattage settings be any safer.   If your personal settings are well within the parameters of the gear you choose.  You are safe, no more, no less.

You now have two choices when selecting your batteries:

Buy batteries based on the maximum range of your device. (just in case you will floor it sometimes)
Buy batteries based on your own personal settings.  (I am disciplined and will never need that much power)

Buying higher rated tires that you are not using is a waste of tread life, Buying batteries rated too high for your setup is a waste of vape time.

Using an ohm’s law calculator, you can figure out the exact amps you need for your application.  Then purchase the battery that is closest to your answer without going over.
Or you can try one of our battery selector charts to give you an even better understanding.
