RBA and Shorting

[otiose]

Noob Questions:-

1. I always read that it is advisable to use a multimeter to check the ohm on the rba first before using it. Doesnt this just check the ohm reading? how does this prevent shorting ?

2. If i were to put my ego twist which I understand is a protected battery on a rba and it shorted, what will happen ? should the battery just stop and I cant fired or the battery will no longer be able to be used ?

3. In a short rba situation, what actually happens to the battery ? what is the science behind it ?

THANKS !!

I can only really answer #1. Basically a short = 0 ohm. It's like just connecting the positive end of the battery to the negative. I think shorts mostly happen in gennies with SS mesh.

I'm not sure how the protection works on the ego and I don't really know the science but I do know a short can cause a battery to over heat and explode or catch fire.

You can only short a mechanical e cig

It will blink and shut off every time you push the button it will blink. No harm done its circuit protected. The ego uses a coil in a circuit you cannot harm a correctly wired ego twist.

3. In a short RBA situation, what actually happens to the battery ? what is the science behind it ?

If you test resistance and it's bouncing around a lot you got problems. Should be steady at whatever ohm the coil is.

If it shorts your ego, your ego is dead. I did it one time one a brand new kgo battery. A really bad short will burn through either the positive or ground wire leading from the battery. Also did it on a smoktech groove. Burned the positive lead coming off the battery. So, the idea that you can only get a short on a mechanical device is wrong. I don't use a multimeter anymore. Just a device that can read ohms will work. Main purpose of a multimeter for me was always finding how long I wanted my coil to be. It SHOULD have the same reading before wrapping it as it does after, if not there is a short somewhere in the coil. Most people are turned away from genesis devices because they think they have to have an ohm meter. You don't have to have one, but it does make it a lot easier when you are starting out.

If you make certain that there isn't a short, using RBA on eGo style batteries is fine. The eGo-C line has stronger short protection than previous versions, the upgrade battery apparently having the strongest.

But I don't put them on an ego unless over 2 ohm & previously tested on a mod with strong protection.

Ego batteries from JT flash a few times & then stop functionality of the button until the offending attachment is removed. I only know because my ego-t usb won't touch anything I've rebuilt without doing it (while both my Twists will run the same thing fine).

To my vague understanding the MOSFET can melt or otherwise be damaged (I assume from too much current) but this short protection should prevent this. But things happen & these batteries weren't designed with RBA in mind.
