Best battery for mech 2017

[Darth Xibalba]

Just ordered a hcigar Skeleton Key mech. It says 510 connection and telescopic silver contact pin/silver firing contact. Does that mean it's not a hybrid & that I don't have to worry about a protruding 510 on the rda/rta? I also was wondering what batteries most people use in their mechs, to be able to sub ohm as low & safe as possible (0.15-0.3). I use Docan cells in all my other mods, except the Hexohms. They're 35A, 20A continuous, 3000mAh. Should I just use one of those in the mech or is there something better?

I don't know what a Docan battery is. But if you're building as low as 0.15 ohms, you're below the CDR of a 20A battery, and in risky territory.
I use mechanicals exclusively, and I mainly use LG HG2s.

Here's a list of recommended batteries and the ratings they tested at from Mooch.

Cool, how low do you typically build and feel safe with those LG HG2's? Those are the pink ones right? Do ya know anything about this mech I'm getting?

Well by the looks of this chart it would seem that a Samsung 30Q, or Sony VTC6 would be the best choice for a mech, having both high amps, and high mAh

I don't have that mech, but all you need to do is follow ohms law for your builds. With a 30A battery, like the HB6, at 3.7V nominal, and some sort of safety buffer, you could go as low as 0.15 ohm with a 25A draw on that battery. Here's a link to Steam Engine to help. Ohm's law

The higher the capacity, mAh, generally the lower the current, so a 30Q will give you 20A and 3000 mAh, whereas an HB6 can deliver 30A but only with 1500 mAh. Choose your battery based on what build you want. Going with a bit higher ohm build will let you use something like a 30Q and have better battery life.

You should really take the time to learn how Ohm's law relates to vaping and battery safety.

You should also take time to learn how to use a mechanical.
Your posts show you really don't understand the risks or how tonuse it safely.

Its not hard or difficult, but ignoring it will eventually get you hurt or worse.

Here's a good place to start.

What's the difference between the HB2,HB4,&HB6? It looks like they all have the same specs according to that chart

Different versions.

--->LG HB2 30A 1500mAh 18650 Retest Results...a great 30A battery, about equal to VTC3
--->LG HB4 30A 1500mAh 18650 Bench Test Results...a fantastic 30A battery, beats HB6 when pulsed!
---> LG HB4 "Mustard" 30A 1500mAh 18650 Bench Test Results...a great 30A battery, better than brown HB4
---> LG HB6 30A 1500mAh 18650 Bench Retest Results...a fantastic 30A battery, but low capacity
---> LG HB6 Pink 30A 1500mAh 18650 Bench Test Results...great 32A/1500mAh battery, better than ivory HB6

If you don't understand the above I'd hold off putting any battery into a mech at .15Ω until you do.

Is just saying "ditto" an appropriate reaponse?

Ok... ok... I'll add that there is currently an inverse relationship between mAh (battery life) and amps. The higher the amps, the shorter the life. I find it far more preferable to carry spares in a case than to try risky builds on a longer lasting battery. Most all my mechs are running on LG HB2s, 4s, and 6s. The 4s tend to last a smidge longer...

To begin with I wouldn't in my right mind use a 0.15 ohm coil on a mechanical. Common ohm readers are not accurate enough to measure resistances that low, and you could find yourself messing around with a coil well below your desired 0.15 ohms.

My rule of thumb is to never go below 50% of rated CDR, which would mean nothing lower than 0.4 ohms on a 20 amp CDR battery. (tastes better anyway)

 

[Bad Ninja]

.15 ohm builds on a single 18650 is asking for trouble.
You can do it safely with multiple cells, but again you ned to know what you are doing.

 

[Darth Xibalba]

Yeah I'll probably keep it at .2 and above just to be safe. But the app I have does say that for the LG HB6 a .09 is possible

You need to get a better app! At .09 you're pulling roughly 47 amps off of a 30 amp battery. Not good. At .2, you're ok at roughly 22 amps.

You are either entering a value into the app incorrectly or the app is flat out wrong and giving dangerous info.

4.2v / .09Ω = 46.6a
4v / .09Ω = 44.4a
3.7v / .09Ω = 41.1a
3.5v / .09Ω = 38.8a
3.2 / .09Ω 35.5a

Drawing more than the CDR of any battery is playing Russian roulette.

...and the CDR rating drops as the cell ages.

It's called vape tool pro. You don't have to enter anything, it has a battery database, with all the specs for each

 

[Topwater Elvis]

If it is implying that a 30a CDR cell can power a .09Ω resistance safely,
it is flat out wrong & completely unsafe.
I wouldn't rely on or continue to use a dangerously bogus app.

The figures I gave in the previous response are accurate & correct.

I use that app... ignore the database... use the ohms law calculator and the mfr CDR with a safety margin. The database is based on the nominal voltage (typically 3.7 v) and the estimated max vaping current, and assumes a perfect battery. You know what assuming does, right?

I've never really understood why people new to mech's feel the need to jump into the deep end with very low ohm builds. You can get a very good vape at much higher resistance levels, it just takes a little time, research and practice. To be honest you really need to understand how the mod works, the limits of the batteries that you use, the accuracy of any ohm reader and your own limits before you even contemplate a 0.15 build. If you can't invest some time and effort into learning the ropes first, just use a regulated mod. You need to properly understand the risks and be able to identify any warning signs that something is not right before you use a mech.

Lots of people on here will help you if you decide to use a mech but in the end you are responsible for your own safety.
