@GraceH Small world! I used to live in Richmond and dated a girl that went to WKU...
Well sure... I've got AW IMR 700mah's. I had made statements that I figured they'd last as long as my 650 twists, but everyone said no due to the Vamo having more electronics... But these are lasting me longer than the twists did...
Great info, thanks!Your average eGo battery is quite possibly from the bottom bin of the lowest quality batteries obtainable by man. Read: High internal resistance. AW batteries are regarded as decent to high quality batteries, and most likely have lots less internal resistance. Less amperage wasted to heat generation.
Internal resistance is also most likely the reason why people think new batteries "wake up" after a handful of cycles. Normally, with lithium batteries, the internal resistance will lower somewhat during the first few charge cycles, giving somewhat more oomph due to less ohm. Something something formation-something.
... or so rumor has it.
Might also have something to do with ... well... size. And not as in capacity by itself.
Battery size not only dictate capacity, but also discharge ratings. A batteries capacity is ... duh... rated in milli-amp hours. Take a 2100mah battery. Should be 1 hour worth of delivering 2100mA, or 2.1A. This rate is called 1"C". Pulling twice this, 4.2A would be 2C. Etc.
For a 700mah cell to deliver 2.1A, it would be pulling 3C. Working harder to deliver the same amps. Wasting more energy to heating up the battery and not your coil. 3C should be no problem, but when we're talking 15-20w+ vaping on low-res setups, this theory becomes practice quite quickly. Where a 2100cell discharge at, say 10C, the 700cell would be at 30C to deliver the same amperage. Not recommended with random no-name batteries of questionable origin and chemistry.
When I began researching mods I made many comments, on ECF and elsewhere, that I thought the 18350 would last as long as my 650mah spinner and be the batt for me. EVERYONE said "oh no, don't be silly, an 18350 will only last a couple of hours, you'll need to carry at least 2 back-ups with you to get a full day". Well I'm rockin my brand new Vamo V2.5 at with a ProTank at 4 volts, and have been since 6am today. I still have a 3.6v charge left. Am I glad that I did buy 2 18650's too? Sure, they will come in handy for camping and outings. But for day to day, I'm thinking these 18350's are a winner! One thing I am wondering though, people have told me that new batteries take time to "break in" and will hold a charge a bit longer after they do. Can anyone verify that?
PS, LOVING THESE 18350's lol
A real man uses a 18650s not them there little girly 18350s Thems fore sissys;-)
