Samsung 25R VS Tesiyi battery

[Jeremy007]

In sub ohm vaping, Samsung 25R get warm, Tesiyi still cool.

Is this guy in the video for real?  You can not test the amperage capacity of a battery with a multi-meter, unless you have a load, and possibly a shunt.  I don't know who this guy is, but, he definitely does not  understand electricity.  First his multi-meter is set on miliamps, and his leads are not in the correct plugs.  With a Fluke he must have the red lead in the far left plug to measure amprage.  The latest version of the Fluke 87V has a limit of 10A continuous and 20A for 30 seconds.  In order to measure amps your battery must be under a load.  You have to get amps from somewhere....  Ohm's law is Ohm's law.  In order to have Amps, you must have Volts and Resistance.  He has Volts in the battery, but has no resistance.  In order to test a battery under load you need something like this:   Computerized Battery Analyzer (CBA) and CBA A2 500W Amplifier

Here is a real test of the battery, and it isn't bad.  It isn't better than a 25R, but it isn't worse.  A battery has to be chosen based on the needs of the user, not the maximum amps.

Here is a real test of the battery:  Tesiyi 40A

His calibrated fingertip temperature probes are not really scientific either.

Agreed!

The battery is essentially being short-circuited through the meter. As the only thing limiting the current is the resistance of the wiring, connections, and the fuse.  Useless for determining the battery's rating and a really bad thing to do to the meter!
