Why is a 21700 battery high voltage?

High Voltage. A high voltage is desirable in a 21700 battery because different batteries will deliver different voltages. For vapers using a mechanical device, a battery with a higher voltage will “hit harder” and deliver more current to the coil, therefore creating more vapor.

What is the capacity of a Sony VTC6A battery?

How many amps can a battery discharge?

Some batteries with a high current rating are able to discharge up to 30A without overheating. However, this doesn’t mean that you should just go out and buy the battery with the highest current rating. While this would definitely be the safest approach, you would be sacrificing battery capacity in return. Instead, you should use Ohm’s Law to properly calculate the amps you will be drawing from your battery and pick a battery that is rated comfortably above that.

Why is it important to have a battery that runs at a safe temperature?

Heat is the number one cause of aging and damage to batteries, and a battery that runs too hot will greatly shorten its lifespan.

Unfortunately for the cell, though, initial testing from Kidney Puncher suggests a fairly poor performance, dropping to around 2,100 mAh when tested under vaping-like conditions on a 0.2 ohm coil (meaning 21 A at the full 4.2 V). Still a great option for the amp limit alone, though, and more than enough for many vapers' purposes.

What is the true rating of a vape battery?

The cell advertises itself as 40A, but based on testing by vaping battery expert Mooch, the true rating is 30A. However, this is still a more than respectable rating for battery and the performance is great up to this level.

What is the maximum A for a VTC4?

However, testing suggests that the 5A tops out at 25 A and the VTC4 is ideally used at a maximum of 20 A. Both of these can technically exceed these ratings (and be used at 30 A as the manufacturers suggest), but for longevity you’d be better off keeping the current slightly lower.
