Did you get your IMR10440 yet??

 

[Katya]

It's here! The first IMR10440 High Drain Battery!
Another First, Only Available at Clouds of Vapor!

Make that wimpy 10440 mod Rock! 3.7v 350mAH. Only $6.99 each.

I don't even own a wimpy mod yet, but I've been eying the Little Sister for a while because it's small and variable voltage. It uses two 10440 batteries (3,7v, 350 mAh). Would you recommend that I use your IMR High Drain instead and why?

[Hi, Drozd! ]

Yes,
I would recommend them.
The make my Little Sister Rock.
The High drain batteries hold the voltage steady, so your 1st vape is as good as your last!

Thanks, BB. I'm still on the fence, not about the batteries, but about the LS. I hear it only lasts 2-3 hours. And I love my Riva and my eGo.

BTW, your LR cartomizers are wonderful, except I keep forgetting that I'm using LR and I already burned two of them. I'm so bad at LR. I like moderate resistance cartos, 2.4-2.6Ω range.

Thanks for your response.

 

[Drozd]

hey BB... could you possibly provide the tech specs on the IMR 10440 batteries.... I mean as far as C rate and all that... (same thing I had to ask about the IMR 14500 before (you should really think about putting that info on your site))



[Hi Katya] *once you know what voltage, what resistance, and what battery....we can throw together the quick and dirty math to give you a pretty close rough guess as far as how may continuous seconds the battery would last (you'd of course break that up as far as how long you press the button and how many times you press the button in an hour on average).....but yeah I'd suspect that something using a small battery like a 10440 size is only going to run about that long....

I'm in the market for some new 3v batteries in the next couple of weeks and currently don't have a ton of time or the patience to search for the answers myself. I've been stacking two Tenergy 750mah RCR123A's LiFePO4 and they aren't lasting as long as they used too. I've been using the charger that came with these batteries and made the mistake of charging a newer set of 3v Tenergy RCR123A Li-ION batteries with this charger which pretty much killed them instead of using the charger those batteries came with. Anyway those are the two chargers I have for my 3v batteries. Other than purchasing these exact two types of 3v batteries again what other (and better) options are there that will work with the chargers mentioned? The one mod can use the 16340 batteries (and I do have a charger for them) the other can't so I figure for now I'll just stick with the 3v batts for now? Thanks for the assistance.

Hi Aaron,

I am not a big fan of LiPo. I have not had very good life out of them.
I am a big fan of IMR High Drains. I have them in almost all sizes.
If I don't want to use IMR's since they only come in 3.7v, I use my regular Li Ion's which are 3.0v. To charge the 3.0v 16340's I use the 3v/3.7v switchable charger on my site.
I hope this helped.

 

[MillDog]

Hello, Got 4 of the IMR 14500 and love them...

 

[Bigbuyer]

Hi Milldog,
This has come from Missy. The combo of LR and High Drain puts too much stress on the circuitry. You end up with a collapsed spring and a burnt switch.

 

[JuniorNA]

Hey bruce. I didnt realize that High drain kept the voltage at a more stable amount. I mean, i did in a way...but I also thought that high drain means that the batteries die sooner because of the constant voltage they were outputting, where as a li-po reduces voltage to last longer. I will order some 18650 high drain from you for my journeyman to see how long they last.

Also, I have your trustfire charger the 3.7 volt for 12.99 - will i be able to charge the cr123 3.0v batteries in there? ON your site it says it will fit the CR123, but will i burn them out with a 3.7v charger when they only are 3v batteries? I want to get the cr123 for 6v vaping to use all these standard resistance attys that I have just sitting around. Thanks !

Hey Bruce and company:

Does anyone happen to know the dimensions of the 22650 batteries on the CoV website? I'm thinking about building a mod around one, but I'm unsure how big around/tall they are. Any chance I can get a size comparison of a 22650 vs. a "C" size battery??

 

[CloudBurst]

The actual number 22650 represents the size as well.
So the 22= 22mm diameter, 65 = 65mm long.
Hope this helps.

 

[0smitty]

Actually, that helps a lot!!! I figured the numbers had some relationship to physical dimensions, but now I understand said relationship. Thanks for the help!

Hi Bruce,

I'm glad I saw this thread. It's so big I only read the first couple pages so apologies for answering a question you may have already answered.

Do you have any IMR High Drains that, stacked, would equal 6v vaping? All I see are 3.7, which would equal a knocked-on-my .... 7.4v.

Thanks!

 

[Bigbuyer]

Sorry, all IMR batteries right now come in 3.7v only. I have the LiFePo4's and the Li-ion in 3v.

Thanks. Now I know I haven't overlooked a possibility.

 

[Grammie]

Got my I IMR10440's today.....do you think I will need the spacers for these particular batteries?

 

[Bigbuyer]

No Grammie, you should be good to go! Enjoy!!
