battery question

My mistake, it turns out Ohm's Law Calculator has a bit of a bug in it, at least with Chrome. The correct amperage for 11w at 1.3 ohms is 2.90887 amps. Still, pretty much every battery out there should be able to put this out. Thanks to Siam Diesel for pointing it out to me.

 

After reading various vaping forums, I agree. The picture that often comes to mind is the young chick that drools aver the latest labelled outrageously expensive handbag/dress, which is made in China in the same factory that makes the one in the market for a 1/100 th of the price. It's a bit crazy TBH.


To be realistic, the ecig and it's derivative mods and RBA's are based on a '60's (or is that '50's) design. It's never been rethought just tinkered with. How does a $160 mod justify it's price over an $70 or less mod. other than label and fad.

 

Not trying to hijack the thread but it is kinda in the ball park for what I am getting confused over.

I am seeing all these 30A and higher batteries coming out now and fully realise that this is the max amp discharge rate for that battery and is important for sub ohm etc. What I need to find is the max amp discharge rate for the normal AW and Efest batteries so I can make sure I stay within the limits.

This has come on since I have started rebuilding and have a mech mod on the way. I just don't want to take the risk of pushing the limits of the batteries. If I want to push the sub ohming I will get the appropriate batteries.

Is there a site that I can get the MAX discharge for IW and Efest batteries and the discharge rate specs for them as well?

If so can I gat a link please? I have been looking but am still not locating what I need.

Sorry to take over the thread.

Don't worry, I found it on Tatse your juice. NO IDEA why I hadn't looked there before. I have it book marked and have been trying to find this info for ages but with the wrong terminology. Don't I feel daft. lol

 

Just be extra safe and buy the new Efest 35A 18650s. Go down to .12Ω at 4.2v without having to worry.

 

Many thanks for that Ryan.

Not looking at ultra low ohms so not an issue for me. If I ever wnat to experiment at that I will, of course get the appropriate battery, but for now I just want to stay safe and have calculated a 5.4A draw at 15W on a 0.5 ohm coil. That is lower than I have ANY intention of going and wives a iA buffer for the max draw on an Efest 18350 800mAh. So I should be ok. I will also be using a Kick 2 in the mod for the safety as well so can regulate my power that way and be sure of my Amp discharge. I think a 1 A buffer is safe. Still got to fully check that out when I can find it.

As I say I am not getting in to cloud chasing but just want to go to 0.8 or so to experiment with it a bit and for coil building fun, as in different coils than plain micro coils.

Thanks again for the info.

Should point out I have calculated on my lowest Amp discharge rate battery.

 

.12 ohms! at 4.2 volts! the only reason to do that is for the sake of saying you did it in my opinion.

not hijacking the thread, its a good extension of the existing conversation

 

I'm with you mate. That's just for extreme cloud chasing in my opinion and that is mainly done for the wow factor. I'm 51yrs old. The only wow factor I'm interested in is with the missus

I do like to get a few clouds going but I don't see the need for that kind of risk factor if a mistake is made. Hell I use 30/70 juice for christ sakes.

 

I don't look at it like permission to go low, the way I look at it is you can easily survive a short without venting the battery. The higher amperage capability means a more durable battery, you can charge faster without damaging it, you don't get as much voltage droop, etc. Standard car analogy: you do 99% of your driving using less than 75hp, does that mean you should get a car with a 75hp engine? Of course not, you want a damn Hemi for that 1%. The cost difference between a shitty battery, an AW IMR, and a Sony 30A or Efest 35A is so low, it isn't even a question for me.

 

I agree whole heartedly. I just don't have any high amp batteries. Also I wanted to look at it for usind the mech in 350/500/490 mode as well for out and about. Just erring on the side of caution. I only have AW and Efest so I am happy with the quality. I have heard alot about the Sony batteries, can't remember the name for sure vtc4 maybe?, But I am happy with what I have and have no requirement as yet to buy more batteries. If I go below 0.8 or so I will definitely be getting the higher amp batteries though.
