Do remember tghis is a parallel 2 battery mech, not 2 battery series mech. Important is calculating your amp draw as the voltage does not "double" the voltage as a series mech will. Here's a mech safety poster that can help you out.

Edit: Oh, and note that's at a full charge of 4.2V. As you use the batteries the voltage will drop, changing the amp draw accordingly. A 3.7V nominal (what the battery is actually "rated" at, but is 4.2V with a full charge) can actually be a useful number to plug in when calculating your load on the batteries.

Those are the exact number i punched into the ohms calculator lol. As well as a few others.

I dont plan on running just one battery in the mod, even though it can be used with one or two batteries, i still plan om always using two. At least for now anyways.

The way i see it, any one can read/follow directions and have a positive end result, but that doesn't mean you understand what you're doing, it just means you know how to follow directions. Following directions isnt good enough for mech mods. Before you even put batteries in a mech mod, you should have a clear understanding and be 100% positive you know what you're doing before firing one up. Thats why i asked so many questions. I want to be 100% sure. I could watch 7000 videos and follow directions for multiple builds all day everyday, doesnt mean i understand/know what im doing. I dont want to be that guy that does that, thinks he knows it all because he read a few articles and watched a bunch of youtube videos. Id much rather ask questions and be confident with a clear understand of what im doing and why.

Awesome info/advice guys. Thank you very much for being patient. Now running two fully charged batteries doesnt double the volts and or amps right? Does it stay 4.2v and 20amps since they are matching batteries, or does it stay 4.2v but raises to 40amps?

Ahhhh there we go. Thats what i was looking for. Thank you

Depends on the setup. Yours is parallel so the volts stay the same and the amp load is "split" between the two batteries (essentially each battery pushes half the load and only "feels" half the amps, so you could technically draw up to 40A on the two batts.)

In a series configuration, on the other hand, the voltage is doubled, and the full amp load is "felt" by each battery.

Both of these allow you to reach higher watts than a single-battery setup, but each by different methods. Parallel increases the amp limit, allowing you to build lower resistances to achieve more watts. Series increases the voltage, which gives more watts at a given resistance, but also REQUIRES higher resistances be used (wattage goes up as the SQUARED inverse of the resistance, though, so you still end up with twice the watts when both volts and ohms are doubled.)

I watched a video of someone reviewing a different mech mod and he said max wattage for that particular mod was 200w. Thats why i asked about mine. Sorry for wanting make sure i know the limits of my mod.

Anyone who offers a video review who talks about "max watts" on a mech mod as a "spec" should simply be shot ignored, as they are clueless to rely on for any advice.

I'm sure he read that off the box, but it makes you wonder what on earth a figure like that is based on. MOST mechs don't have stats like that, because what does it even mean? That's like buying a funnel and asking how many gallons it'll hold. There might be one smartass out there who'll sell you a "200 gallon funnel" but that doesn't change the fact that it really all depends on your bucket.

Ok i gachya. I assumed that he meant you can build your coils at whatever amps your batteries can handle, as long as your build doesnt exceed 200w. Since batteries and electrical devices all have limits, i figured the internals of the mod had their limits before they started to fail. Granted i know there's no chips or wires, but there are a few parts and pieces they are built with so assumed they would have limits as well. But now it makes sense that the batteries are the weak spot and if the build isnt right, the batteries will fail before the mod

I mean, that' all true, too, but it's going to depend on things like how well you clean and care for your device and how much "mojo" was in the universe on the day it was made, as much as it will on the make and model.

Some one said to read baditubes blog. Im reading his blog and this was linked in the suggested blog to read.

Punching the numbers into the ohms calculator says it will work.

This is why i ask questions. Im looking into the things and trying to learn the things everyones telling me to. If punching it into the ohms calculator say it will work then how come you guys are saying it wont?
Isnt that why you make coils to the resistance that will allow the correct amps to work safely?

If i punch in the ohm calculator
4.2v
3.5 amp
1.2r
14.7 w.
The batteries are 6.7-6.8amp. I dont understand why that wont work

The most recommended batteries that anyone here will recommend are authentic Sony, Samsung, or LG.

Your panisonic batteries are 4.9a.
You obviously didn't read the links I provided.

Sure you can use 2 4.9a CDR cells with high enough resistance coil(s).
When I said not to use those cells in mech I had no idea anyone would buy a dual cell mech & rba with the goal of duplicating the vape from an ego twist.

It has nothing to do with using them under any specific watt, it is getting even a half decent vape without exceeding the CDR.

I did read your links. I posted the numbers i said before i seen your post w the links. I was typing before you posted it and didnt refresh the page so i didnt see it until after i had already typed n posted mine.

With a few different ppl saying two of the batteries i got i shouldnt have got and keep telling me to learn ohms law made it sound like they wouldnt work and it was driving me crazy trying to figure out why they wouldnt work/shouldnt have got them/got the wrong ones.
