2-in-1 Ohm & Voltage Meter

[Grateful4jerry]

Basically, it depends on the ohms of the load, and the amp output capabilities of the battery. So ....it depends. lol.

For 18650 mechs with good batteries....not much sag on standard loads. (High drain battery, after all).
For a smaller regulated e-cigs....the lower the ohms, the more sag...because the battery has an internal resistance and can't keep up. Also...the electronics may limit it (and rightly so). Over-amping a battery is how it heats up and goes thermal.

Also, depending on how the voltmeter is, various regulated e-cigs boost the voltage to the VV setting and use PWM...so they (the volt meter) don't always give the proper reading. It depends again.

So what is it that you're testing? If for a mech, it would test battery voltage. But so could a meter without a special rig. Although a special rig is handy since it's hard to get the probe to stay on the center pin and not touch the shell and short it. You should probably take the battery out in that case...it's easier (when using a DMM).

So I guess you're right....more for testing unloaded battery voltage on mechs. Meh.

The other voltage stuff is a continual point of contention in the e-cig world. nm, I guess.

P.S.
Nice AVI. My late brother was a deadhead. No pun intended.

Thanks for the response! I was thinking it could be a convenient way (for me) to be able to keep an eye on mech's battery voltage while out and about without relying soley on quality of vape to let me know. I usually pull them sooner than i need to( luckily never too late), but I guess that's a good thing. Your brother must've been a good man

Hello,
but this 510 volt meter display 0,0 or 0,00
Thanks in adv for help.

I have the ohm meter from madvapes and as with the one the OP cites, you need a 510 to eGo adapter for most clearos. The problem is that the connection on most adapters is spotty. In a 10 pack, you might get 6 or 7 that work reliably. I recently got this 'well' adapter:

510 to eGo Adapter with Well

It has a spring loaded center pin which virtually insures a good connection. Good for eGo and 510 connections alike. It's 50 cents more than their regular 510 to eGo adapter.

I also have a multimeter and check the calibration of the ohm meter with the multimeter. The ohm meter is easier, quick check when you think the coil's getting gunked up and may need a cleaning and I always check before and after cleaning - tells me when a coil is ready to be pitched. One note - don't crank down on the clearos onto the connection - easy to do when it's dead and you don't think you're getting a connection - getting a clearo out of the well adapter would be harder to do but it's a better connection than most adapters.

Please explain how this works.

Thanks.

For voltage checks I prefer an O-Scope

Hmmmm... I do need one. Thanks for posting this!
