New to Mech Mods

[cburcet]

Hey Everyone,

I have been vaping for about a year and a half now and have gotten my first mech mod. I got a Tuglyfe box mod and have some questions for your guys. I did the math on the batteries and voltages but wanted to run them by someone who knows. I am using 2 Brillipower 18650 3100mAh batteries that are 4.2 volts fully charged and have a max discharge of 40amp. I am using a vector RDA that is set at exaclty 0.33ohms. With that info, i got that the continuous is at 12.7272 which means i should be good to go but want to be sure.

C.

Thanks for the info Rabbit. I had a feeling the info on the battery was false after i found a chart online but this link beyond confirmed it. Any recommendations for a good battery to use with this mech mod?

First welcome to VU.
Second here is link to the actual specs of the batteries you have. The https://www.reddit.com/r/electronic...1ra/brillipower_40a_3100mah_18650_bench_test/

Your math is correct and in a parallel box figure 1.5 times the continuous amp limit of the battery . So if we pick the low end of what Mooch found in his battery tests (15 amp actual continuous discharge rate) *1.5 = 22.5. You have plenty of headroom at a .33ohm build.

Thanks Stereo. just to see if I understand fully, the batteries in parallel have a max discharge of 22.5 so since the discharge rate with the coils in 12.7272 i am in the clear? Sorry for the "dumb" questions but I understand about ohms and electricity but in vaping it is new to me

Yes, you technically have the amp limit of both batteries since they are in parallel and they are sharing the load. However, 1.5 is the multiplier often used to account for any loss and to play it safe. If your box was running in series (like the noisy cricket) the amp limit would remain the same as a single battery but your voltage would double instead. So 8.4 volts instead of 4.2, roughly speaking. You won't actually get quite 8.4 or 4.2 for that matter at the atty.

Thanks Stereo. I was looking into changing the batteries i have and want your opinion. I am thinking of either the LG HD2C or the Sony VTC4. Which would be better for the box mod?

 

[StereoFreeze]

In my parallel mechs I use Samsung 25r's. The samsungs are 20amp. Unless you plan to build really low, less .15, 25 amp batteries are not really needed. If you do plan to build really low VTC4's or the new LG HD2 (the purple one). When they are back in stock I plan to get some of the HD2's. Also Liion wholesale or illumn.com for battery purchases. Skip ebay, amazon, etc.

In case you don't know, I will add that the batteries you are going to use in dual battery mods should be kept together. You will see this term referred to as married. The concept being you keep the usage on the batteries the same. So purchase as a pair and always keep them together. In use, charging, etc. You don't take one of them and put it into a single battery device and then later use it in a two battery mod.

 

[cburcet]

no, definitely. i just ordered 4 of the Samsung 25r. should be here mid week. then i will give that mod a whirl. wasn't working to my liking with the brillipower.

If your not getting the desired ramp up time you might need to change your build up. My go to builds for mech mods are 7 wrap 24 guage nichrome around a 2.5mm bit. Usually comes out to .2 ohms and I use this for single battery mechs. For parallel I go lower and use a 28/38 nichrome fused Clapton at I think around .15ohm's.

Hey Stereo,

Check out this link.... http://www.amazon.com/dp/B01AOEFRBI?tag=upcindex-20

I truly hope this is a clone. My set up that is just like this cost close to 200. Whats your opinion?

 

[StereoFreeze]

Definitely a clone. Read a few of the reviews and some people who ordered it confirm.

@cburcet One more thing I should have mentioned because it's important. The tugboat mod is an unregulated box mod, not a mech mod. I don't mention this for semantics, but because your batteries are not going to be the only thing that limits how low you can build. If you build too low the mosfet protecting the switch can fail and that would not be a good thing. The tugboat parallel box should not have any build lower than .15 so be sure to keep that in mind.

Thanks Stereo. I honestly don't plan on doing any build lower than .3. I am not too comfortable going lower than that. The vulcan is at .33 but i had someone in the store make it for me and they used coils that were pre made from a bag that were clapton.

Hey Stereo, got another Q for you. I just put in fresh Samsung R25s in the mod so in essence based on what you explanied a 0.22 ohm build wich draws 19 amps of power should be ok to run since the mod is running in parallel?

 

[StereoFreeze]

Yep, you are good.

Hi guys, I need some help regarding my maraxus mod its a tube mod. I'm just wondering why does it hits hard when the battery is in reverse position. meaning positive down and negative up. but when the battery is in its normal position it doesnt hit really hard. any thoughts on it? thanks

[StereoFreeze]

I don't know why it would hit harder. Quick google search seems to indicate running your battery backwards is not a great idea. Here is a reddit thread with a short discussion on the topic.

 

[vap3r]

That thread can misinform if read literally. IAmSecretlyACat is wrong in that installing a cell with the positive down will turn the body of the mod positive. The body remains grounded until the circuit is complete. Because the Maraxus is designed with vent holes located near both poles, you are free to install your cell in whichever orientation you desire with the caveat that if you do install your cell with the positive facing the lower vent holes, you need to be particularly vigilant regarding the integrity of your battery wraps. Always orient your cells facing available venting. Always verify the integrity of your wraps before cell installation.

Thanks Stereo. I appreciate you help and patience. Here is the final build working perfectly.

Hi! So that means it's really okay to use my battery in reverse? Thank you so much. Anyway im using sony vtc 5 battery and AWT yellow 40amps..

@vap3r thanks for the clarification.
