HELP. my RDA having or mod has problems

[tjgiants12]

When I fire my rda on my tube mod it stops firing after a couple seconds. Before I finish my hit. I've had other mods before and never had this problem. Just got this new mod. I thought it could be a short maybe but a new coil didn't change anything. Could it be my battery? Im using a mxjo 18650 30 amp battery. Help please

tube mod... is there battery rattle?, shake mod with battery inside, what do you hear? anything? rattle?

 

[tjgiants12]

No rattle or anything

How low is your ohms resistance? Just call it a feeling but I'm guessing below .2 ohms?

 

[Spencer87]

Clean the contacts... take the mod completely aprart, clean contacts put back together, check your battery though, if it is dead, you dont wanna still be using

 

[tjgiants12]

Not positive but probably around there. I don't have an ohm reader but have used this build before

 

[tjgiants12]

Battery not dead. Full charge

 

[Spencer87]

oh holdup
Check the contact with atty and mod. Maybe the bottom of the atty unscrew that out a bit... make sure that your atty is touching the contact pin to the mod

Could be you're pushing your battery too hard too. Size of wire, coil diameter and number of coils?

Edit: Batteries build resistance quickly when pushed hard, it doesn't take long for them to start acting adversely when being pushed to max amps.

I did that. Its pulled out. I think it might be to low of a build. I didn't think that mattered with tube mods though

 

[Spencer87]

it doesnt... its probably not that. it matters if you dont wanna blow your face off though

24 gauge kenthal, 4 wraps, dual coil. Probably about the size of a 3/32 drill bit

Here, you might find this of some use. I think you're working your batteries pretty hard and taking a risk.

 

[Spencer87]

Oh 4 wraps bro.... Calm down with that. I use 6 wraps and sit at 0.27.... 4 wraps there is no battery that can handle that load

What??? Please don't fire that up again. Get an ohm reader before you build another coil & fire it. This is NOT a safe build and I don't need an ohm reader to know that.

it doesn't "matter" in that the mod (if it's a mechanical) will fire ANY build you put on it. It DOES matter if you don't want to blow something up.

Mechanical mods have no safety features. You MUST know your build ohms and what your batteries can handle before using a mechanical mod.

If we are talking about a mech
Mechs are where knowing your build is MOST important there's no electronics to turn off the switch and your face sploded

What exactly is the mod you may be dropping a spring or something

According to Steam Engine that build would be under 0.2 ohms, and draw 25+ amps of current from your battery. That is beyond the maximum continuous discharge rating (CDR) of most high drain batteries. I would strongly suggest you read my Mech Mods 101 (Link in signature.) blog and follow the links it contains. If you're running a mech mod as it sounds, you are pushing it and your battery very hard, inviting a potential battery failure.

EDIT: Also you should never use a mech mod, especially with a RBA, without having a good ohm meter. All in the blog.

Thanks for help everyone. I'll put a different build on. I thought it would be fine cause this is the build that my buddy uses and has had no problems. But I don't want a hole in my face. So. Thanks

PLEASE READ THIS AND BE SURE TO SEE THE PICS !! You should never fire any coil on a mech mod without first measuring the resistance (ohm rating). Never pull more amps than the battery has to offer (so you must know the max continuous amp rating). You MUST buy an Ohm reader or digital multimeter. You must know how to use an Ohm's Law calculator (they are online).

What build works best but is still safe for cloud chasing?
