Batteries & Shorts

[DoubleDecker]

Hey all.

When testing for a short on the mechanical mod itself:

1. What do I need my multimeter set at?
2. Should I get a reading of 0 to indicate there is no short in the body?

I bought a mod off ebay that came with a battery. Apparently it's a Sony VTC4 18650 3.7v 2600mAh.

1. Is there any way to know if this is a knock off?

Thanks!

For new people get an auto ranging meter like.

22-Range Pocket Digital Multimeter - RadioShack.com

Get a ohm tester much easier

2-in-1 Ohm & Voltage Meter

Vtc4 is 2000 and vtc5 is 2600.

What mech? Post pics and others can chime in. Knowing eBay probably it's a clone without seeing items.

Not talking about testing the ohms.

Asking about testing the Mechanical Mod itself for shorts.

Interesting that the seller said it was a VTC4.

When I peel off the sticker that they added, the serial number says VTC5.

I'm really not sure what you are asking. A mech mod is basically a short when you fire the atty. That's why you need some resistance and a battery that can take the high Amps. Of course, everybody should have a decent DMM and not trust the cheap Ohms checkers.
On second thought, if you think there's a short, remove the battery. Set your DMM on continuity. With the button locked and not pressed, connect your leads to the negative side of the 510, and the other lead to the center pin. The buzzer should sound if it has a short.

I know it's a clone.

I'm trying to see how to test the mechanical mod itself for a short. Rather, what my multimeter should be set at and should there or should there not be a reading.



Not test ohms of the RDA.

Check your Amps with Ohms law: V=IxR, so Amps(I) = Volts/Resistance.
Set your DMM on D/C Volts. With your button locked and not being pushed, place the negative lead to the mod body or ground side of the 510 connector, and the positive lead to the 510 connector center pin. If you get voltage then you have a short. You should not get voltage unless you press the button or fire the mod.

I am trying to see if the Mechanical Mod itself has a short. I've read on multiple pages that it can short.


"Short doesn't always occur in the atomizer, test the unit itself as well. To do this with a multi-meter, take out your battery, with one probe touch the positive pin of the mod and another on the body. If the meter shows any kind of resistance, it means the current is flowing and you have a short somewhere."

Yeah, I changed my post to a continuity test.
