Good point on the battery super T. Vwls double check the ones you use. Some sites list AW IMR 18490 1100 mah as having an 8C rating RTD say the AW IMR 18490 1100mah has a 15C rating. I've also found other sites listing a High drain AW IMR 18490 1100 as having 15C. that will make a big difference. The 15C version would be a max continuous amp discharge of 17 amps with a safe load at 70% of max would be 11.55amps. A .39 ohm coil will pull about 11amps on fully charged battery so if using those you should be fine.

However an 8c rating would only be a max discharge rate of 9 amps so you'd not only have no safety margin you'd be exceeding the max amp rating.

I'm digging the matching button and ginormous drip tip! Congrats on snagging that bad gal on the classies!

70% is to allow for headroom and safety because batteries wear out and manufacturers overstate their abilities. As batteries age they become worse because recharging cycles build up their internal resistance - and their ability to hit those discharge rates suffers.

If you are exceeding that from day one then i see a 3d printer for $16k!

Not to worry. The AW IMR 18490 3.7V 1100 mah batts I use are from RTD (I could get them cheaper on Ebay but I won't take that risk - they might not be legit); they have a max continuous discharge rate of 15C and an amp limit of 16.5. My standard go-to coil is drill-twisted 26 gauge Kanthal measuring .4 to .5 Ω. A fresh AW IMR 18490 (4.2 volts) running a coil of .4 Ω resistance pushes a current of 10.5 amps. (As the battery loses juice, amps dip to 9.25 at this resistance.)

I always do my homework - I'm a nut about battery safety. (Turns out my face and hands are important to me )

If you want to simplify things, this chart is cool: Lowest Safe Resistance by Battery. (Still always know your battery though and always use an ohms law calculator- that's my motto. Oh and don't buy batteries that seem crazy-cheap but look like they are legit. Not worth the gamble.)

That problem is being addressed by Robert. The new kit with upgraded contact and spring will make sub-ohm vaping possible without damage to the REO.

There have been many changes in the past few months with more and more Reonauts getting into RBA's for their REO's. With lots of experimentation going on with the low ohms new problems and concerns surfaced.

True to form Robert stepped up and will soon have these kits in hand.

Once the kits are here the new REO's will have upgraded contacts installed. Kits will be available to purchase for installation in other REO's.

Yes Karen - you are exactly right. And I plan to order the kit when it comes available... the reason for the convo in this thread is trying to figure out what to do in the meantime. What this all comes down to is me being responsible enough to look for a solution to a very bad thing I've been doing - dripping and driving.

you like (cough) long, lazy, luxurious, laid-back hits?

LOL I do lung inhales... and I keep going till I feel, er satisfied. Which usually results in an exhale of extreme cloudage. I could definitely see Marylin vaping.

not so - you cannot use a 0.4Ω on a Reo mini, or any Reo, because even assuming your battery can tolerate it - and that varies from one manufacturer to another viz AW v Efest for example cite different maximum constant discharge rates, the spring will not.

There is no evidence available on the ability of the new rebuild kits to make a difference to this, although an uprated spring will be better and a BeCu firing pin will eliminate sparking and dissipate heat better. The constant in all this is the same: you cannot overstress your batteries without risk and you can check this easily with an Ohms law calculator.

I have no wish to make this over-technical and boring, but it is not safe to say that a rebuild kit will be able to change fundamental physical laws. Something about a free lunch springs to mind.

OK you just blew my mind. Regroup. So the sub ohm kit will not do me any good? Well sh........t. (Fill in the middle of that word however you see fit.)

The subohm kit will not do any good if you have a batt with a low continuous discharge rating. SuperT is right, the ultimate deciding factor on how low you can go is your batt. Like you said you have the AW IMR 1100 which is more than capable for your ohm range. So no worries there.

What the kit WILL do for you is significantly lower the voltage drop of the mod. What this means is that there is an inherent resistance in all the parts of your mod, from the spring, to the firing pin, to the 510 connection. Making these parts and connections more conductive (which reduces V-drop) allows more power to be delivered to the coil. This will allow you to do 1 of 2 things; you can either stick with your current coil ohms which will result in a significant boost in performance (more watts) , or you can raise the resistance of the coil (from .4 to .5 for example) and get the same vape (in terms of watts) but extend your battery life (due to less current). The hot spring acts as your protection, and the stock spring that comes on the REO will start to sag and collapse anywhere between 6-8A, and also causes the most V-drop. Robs upgrade kit the new spring is designed to handle subohms so I am under the assumption that it can handle 10-13A without saging (just a guess).

I found this website explains things better than I can, plus I think in formulas and it gives some great examples: Explained: Under Load Voltage Drop | The Vape Break Room

Yeap what SeaNap said, your batteries and the kit will work great. The kit wont fix crap batteries.

Execuse my noobness when it comes to reos but, the only batteries these will take is a 184490? Looking into the reo because dripping and driving sucks.

 

[Filthy-Beast]

the Reo mini 2.1 takes 18490s and the Reo Grand takes 18650.

 

[Un5tab1e]

How much bigger is the 2.1 than a original?

hey thanks for the answer! Will the grand be getting the sub ohm kit as well?

 

[Filthy-Beast]

Yes the kit will work in the mechanical Grands or Mini 2.1. If you like to play with different RBA/RDAs look at the LP grand, it has a low profile drip cup and will work with any of the RBA/RDAs but would not be a good choice for cartos or regular attys.

Button-top 18490s or flat-top 18500s is what I was told by an owner of 5.

AW IMRs are the recommended batteries. Both REOs are designed to use the button top battery. As already mentioned, the 2.1 takes 18490s, the grand takes 18650s. The grand gives you both increased charge duration on the batteries, as well as a full 6ml juice supply. For many folks, a full day's worth of vaping.

There are more than a few owners that are quite pleased with being able to attain the flavor and vapor of dripping while motoring down the highway. Feeding more juice (affectionately known as "squonking") is easily done with one hand, eyes still on the road.

Jj - bro you'll be wanting a grand . any mini - original / 2.0 / 2.1 is very small. It's hard to visualize how small they are until you actually see one in real life. Great awesome mods (I've had 2 2.0's) but I'd suggest starting with a grand. The 6ml bottle and 18650 battery put it over the top. The extra working space to work with the bottle and just filling the bottle is so much worth the small size increase.

A grand is only slightly larger. It's the size of a business card and about as thick as a pack of smokes.


Great to see you here bro

Ya, it has to be a 18650! Looks like I might be getting a grand when they are released with the the sub ohm conversion. I was told mid march, we shall see!
