battery safety with mech mods

[metathirteen]

i want to make the switch to using mech mods but theres some battery safety stuff i want to know that i dont think ive ever read about or heard anybody else mention. im not really interested in subohm builds, i wanna stay at around 1.0ohms but what im curious to know is. lets say i have a battery with an amp limit of 30A. would a clearomizer(cruddy 1.8-2.0ohm older style clearomizer) that fit on the mech mod be ok to use, or do i only have to stick to RDAs? id like to stick to using my kanger subtank mini but was just wondering the outcome. and another thing i was wondering is i hear dont let the voltage get too low, what happens if it does? is there any danger of the battery venting? i assumed it would just get weaker like any other electric cig i used.

also, i believe this is my first post. i made an account and i guess never logged in lol.

I'd suggest sticking with regulated mods if you're just interested in using a tank (especially one with pre-built heads). With a mech mod, you're outputting whatever voltage your battery is at. This means that a fresh battery will output 4.2V, but will slowly start to dip to (ideally) no lower than about 3.6V. If it turns out that you like your tank at 5V or something, you're pretty screwed. You'll never get that 5V out of your mech's batteries.

Additionally, you'll need to take care of your batteries and learn when they need to be charged, replaced, etc. This is something that you'll have to feel out with your experience, and will vary depending on the attached atomizer's resistance.

But like I said, I'd suggest not going the mech route in your case.

You can use any atomiser you want on a mech ( hybrid mech you can't but don't worry about that not worth getting)
Mech mods give out the voltage thats in the battery. Charged battery usually say 4.15 volts. A 2Ω atomiser will therefore be running at 8.6 watts and drawing about 2.1 amps from the battery. As the battery is being used the voltage will go down and so will the watts, battery get to say 3.7v then its 6.8 watts and 1.8 amps.
Most people run their battery down to say 3.5-3.7 volts , though thats up to the person some only go down to 3.9v. Myself I just go by when the vape has diminished a fair bit from a fresh battery , happens to be around 3.7V.

what if the voltage gets too low? would the battery just die, or would it be pushing the battery to work or anything dangerous at all? id like to stick with the subtank mini with the rba deck. i eventually plan on getting an RDA but not until i feel confident with everything i need to know about mech mods. pretty much how everyone explained it so far is how my ego one battery is working so the feeling wouldnt be anything new. i dont mess with variable voltage or anything like that. maybe somewhere in the future ill dabble with that stuff.

Running 30amp batteries in a mech with a clearomizer you will have no issues. The CDR amp limit of a battery doesn't mean you have to use that battery at its max CDR, being your coil in a mech is your only adjustment to affect vapor production, even a 1.0 ohm clearomizer coil will work just fine. I use RTAs mostly with my mechs in the 1.3 to 1.8 ohm range, fresh charge they vape strong, get down near the 3.5 to 3.7v charge range, they still work but the vape is a bit anemic. Get a mech like the Nemesis that comes with a kick extension ring, you could even put a kick circuit into the mech near the positive pin at top, just set the dial to your desired wattage, max 15 watts with a newer version kick circuit, and it will output that wattage through the full duty cycle like a regulated. Just remember, being you are not using your batteries at maximum output they way you are describing, they will run you a long time, on my Nemesis when I run a Kayfun on it with a 1.5ohmish coil, I get about 1/2 a day chain vaping on it before needing a tank top off and battery swap out.

Going to be using a Subtank, definitely make sure the mech top cap with the 510 connection has an adjustable 510 pin and that the Subtank 510pin doesn't get recessed, don't force to much pressure on it, take the top cap off, put the tank onto it, adjust the pin to make contact, then put that assembly back onto the mech. Don't use that tank with a SMPL or other direct to battery top cap connection.

Looks like your questions have been covered. You do need to have an ohm reader to measure your builds/stock coils when using a mech.

But if you are interested in learning more, below is my post for someone new to mech mods and/or rebuildables.
__________

When considering how low you can build you need to give yourself some headroom. I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A battery (like the Samsung 25r), that would be 10A. This Ohm's Law Calculator tells me that a 0.4Ω build is as low as I would want to use.

The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, a 20A battery may only be a 10A battery."

With a 30A battery (like the LG HB6), 0.28Ω is the lowest I would build.

I highly recommend you spend some time with @Baditude & @Mooch (two of our resident battery/safety experts) and visit their blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Here are links to some of Mooch's blogs:

• No matter what is printed on the battery wrapper: There are no 18650 batteries with a genuine rating over 30A!
• Links to all his battery tests to date: List of My Battery Tests | Mooch's Blog
• Picking a Safe Battery to Vape With: Table of 18650 Battery Safety Grades | Mooch's Blog

Hand several links to Baditude's Blog - Table of Contents: The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:

1: Yes a clearomizer will be fine on your mech.

2: If battery voltage drops too low (something like 2.5 volts) you won't be able to recharge it.

You can use mechs with space for a kick module to get the reliability of a mech and the voltage regulation and protections of a regulated mod.
Most of my kick modules fire down to 1.2 ohms. Most of my coils are 2+ ohms.
