Batteries batteries everywhere IMR this PCB Protected that, C ='s what? My head is spinning

[twolostminds]

So I've learned enough about batteries to know I don't know enough about batteries. I've read warnings on charging, storage, usage, and seen videos of them exploding while sitting there doing nothing after being charged. Oy Vey!

I've read the stuff on taste your juice and headed on over to RTDVapor to see what is available. I sit there staring at all the batteries more confused than when I started. Thinking I may need to double fist some coffee and start over. lol

I am looking for a couple 18650 batteries for the Sigelei 20W I just ordered from fasttech. I run my MVP 2.0 2600 mAh with coils ranging from 1.6 to 2.0 Ohm's at 8.5 to 10 Watts and it lasts a day and a half so I am thinking 3000 mAh to 3200 mAh's for the 20W Sigelei should be good for 2 full days. Am I making a good guess-timate?

I read that some batteries drop off in performance more than others but couldn't make use of the chart showing which was better because I am color blind and couldn't distinguish the different lines on the chart. What batteries would you all suggest for my current needs? I am also considering getting a Igo W3 RBA loaded with .9 Ohm coils and a Ibtanked with 2.0 or 2.5 cartos's Would I need a different battery for those toppers?

I am also torn between the Xtar VP1, Nitecore Intellicharge I4 or the Elfest LUC, what do you guys think?

Get these: Sony VTC5
And this: Xtar VP1
The only place to get batteries is rtdvapor.com, IMHO

I second the above recommendation

They are certainly the best batteries and charger available for ecig applications - one soon finds that high drain ability of batteries is most important

I have both the Xtar and Nitecorei4.....both are great chargers. You won't be disappointed in either one. As for batteries RTDVapor or Orbtronic are very good vendors. I just ordered these batteries from Orbtronic w/free shipping.

I aggree with these batteries. At 2600 mAh and 30A max discharge they are IMO the best battery for the Sigelei 20W and for sub ohm use.

The Panasonic 3400 mAh NCR18650B are only rated for 6.8A continuous. I would not use these in the Sigelei 20W, nor in a sub ohm setup. The Sony will also probably last almost as long at higher power because they will have less voltage drop.

RTD Vapor is a great place to buy batteries. So is Orbtronic and Illumination Supply. None of these shops will sell you counterfeit batteries.

Out of the chargers you list I would go with either the Xtar or the LUC.

Have fun and vape on

I agree with this. That battery is not ideal for use in a mod, especially a regulated mod due to it low continuous discharge rating in amps, high internal resistance, and not being a high drain battery.

This battery is best suited for low drain applications like a flashlight. There's much more to choosing a battery than just picking the one with a lot of mAh.

Can I run my Itaste SVD on the Sony VTC5 18650 batteries?

I have a K100 and would like the batteries to be multi-purpose.

Yes you can.

Ordinarily I would say that you don't need an ultra-high amp battery like the SonyVTC5 for a regulated mod (10 amps is plenty, any more would be overkill), but since you'll be sharing these batteries with a mechanical mod (and an RBA with sub-ohms?) this would be a good choice for double duty.

Did you mean an unregulated mod?

I use these and run them at <10W output in a regulated Mod. The rated 6.8A at a min battery voltage of say 3V (they do not get this low, mine shuts off at 3.3V) is a power of 20.4W, throw in a safety factor of 50% and under 10W use I would think is acceptable.

Am I missing something?

 

[Baditude]

For WhazatU:

Regulated mods use pulse width modultation in their buck boost circuitry to create higher voltage than the 3.7 volts of our lithium batteries. This is what some people call the "rattlesnake effect".

This process uses multiple high frequency electrical pulses many times a second delivered to the atomizer coil. The voltage which you set the processor to give to the coil is the "mean" or average output, however the processor may need to deliver twice that output to actually deliver that mean. On an oscelloscope, this process is observed as a wave form. The upper "spikes" in the wave form is this 2X voltage which pulls more amps than what the "mean" actually is. The amp draw on the battery can be twice what the mean is. This requires a true high drain battery.

This can be difficult to understand, and even harder to try to explain. This is how Provape explained it to me:

And a followup explanation in this thread:

http://www.e-cigarette-forum.com/forum/provape/524874-question-tech-engineers-provape.html

The Panasonic NCR18650B 3400 mAh battery has high internal resistance, a lower continuous amp rating (6.8 amp continuous), and not being a high drain battery going against it. It's hybrid chemistry is heavily weighted toward the ICR side of the fence, and performs like an ICR battery. How do you think they can pack so many mAh into the battery, just like ICR batteries have?

This battery will function in a regulated mod, sure. But its limitations will not allow the regulated mod to perform at its optimum performance like the manufacturer designed it to.

All true 18650 high drain batteries have low internal resistance and a continuous discharge amp rating of at least 10 amps. The hybrid Pansonic NCR18650PD and PF series have the highest mAh rating (2900 mAh) currently on the market and still have 10 amps, low internal resistance, and still be considered a high drain battery.

Baditude,

Thank you for the quick response and additional education on batteries. So much to learn and so little time and I have a long way to go!

Good points. Not that hard to understand (used to design switch mode power supplies, my first job right out of school). While this battery's rated ESR is 45 mohms, I found a test data set using continuous current that shows a calculated an ESR of 110 mohms. This compares to an identical test data set for the AW 700 mAh 18350 battery that shows a calculated ESR of 90 mohms. The Provape link you indicated recommends the AW battery but cautions it does not have much margin at higher power levels due to it's ESR. That is also true for this battery, but even more so due to its slightly higher ESR (20 mohms).

Bottom line: Good points and good reading. I think I'm ok with the low power levels I'm using. If you use them at higher levels, you run the risk of not having them perform as well. Even if those power levels are within the capability of your mod's circuitry.

Thank you!

Thanks for all the great information guys and the additional links they all really helped me understand what and why I need it.

Placed my order for ^^these^^ last night from RTD and got my shipping confirmation this morning. FAST It'll still be a couple weeks until I get my Sigelei 20W from FastTech and I was wondering when it comes time to use the VP1 to charge the new VTC5's for the first time should I charge them in any special way to ensure performance and longevity?

No special way. Just be sure to put the positive end of the battery pointing toward the display screen. Remove the batteries soon after they have reached their full charge on the charger.

It may take a few charge cycles for the batteries to achieve their optimum charge capacity. And by this, I mean a few charge and discharge cycles.

You won't be disappointed, great all purpose setup. Charge them fully before using. I charge my batteries at the end of the day at 250mah, no real reason behind that other than the fact I'm in no hurry. They will easily handle the 1000mah setting.
