Question about batteries

[ricisking]

So today I purchased 2 Sony US18650VTC3 1600mah batteries that have a max continuous discharge of 30amps. I bought this because I believe it's safer since my rebuildables are drawing 5-8amps. This gives me enough room. However, I then asked myself, why is it that people still buy batteries with lower max cont./pulse discharge? hope this makes sense.

I assume you already use that link or have a similar one.

With a fresh battery (4.2v), you are looking at a possible 30 amps/126 watts/0.14 coil. Is that your intention?

Using an IMR battery that is more standard to the vaping crowd at 10 amps max continuous discharge rate...
Freshly charged @4.2v = 42 watts with a 0.42 ohm coil.

I'm not well versed in this subject either, but I don't see how 30 amps will be necessary unless you are going for a new record.


Edit: I wasn't clear on continuous discharge. A pulse discharge is considered to be around 5 or more seconds, and batteries rated at 10amp continuous have higher pulse discharge rates. With a 30 amp continuous discharge and a short, you have the possibility of a melt down that I would not want to be around for. The battery will continue to discharge electricity wherever it can and not vent or fail until it reaches it's limits. Imagine a metal tube mod getting 3 times hotter before the battery vents or explodes. Sorry, but those batteries seem even more dangerous the acclaimed AW's and Efest's that everyone's been using all along.

I know that 30 amps might be too high for most but then isn't it always better to be safer than safe?

also, some of the coils that I build are within the range of .5-.7 ohms. I don't intend to go lower than that.

Well here's the link on a thread regarding this battery.

It has great reviews. Also, the guy who made the thread mentioned that sony manufactured it to collapse incase it shorts. I'm guessing he means it'll stop working.

You seem dead set on using those batteries. I defer to the wisdom gained from far more experienced vaping gurus. I hope one comes along to address this issue for you. Sub-ohm vaping in the .5 -.7 area is beyond the purview of the "New Members Forum", the danger involved is much higher than one might expect regardless of the hype. I would not do that if I were you, consider yourself warned. You should ask this question in the "Ask The Veterans" section.

Just note that Amps are not the only factor. What happens during failure is a factor. And how it happens (and how often) is a factor.

They may be great or they may not, IDK.
