Calling All Battery/electrical Guru's

[Brian]

Below is some info on battery life that I copied form vaprlife. Can someone tell me how the 1400ma (bolded and underlined) was calculated? Also, would the life be different if you used a 510 atty? I seem to recall reading somewhere that the 510 uses more power, but can't remember the specifics. Thanks in advance!

From VAPRLIFE.COM:

The VP1 has 360mah batteries (milli amp Hours) meaning if you press the button and don't let up, it will supply 360 ma per hour. Now the 801 atomizer is roughly 3ohms, after tests the atomizers draw 1.4 amps when in use. So 1.4 x 3 =4.2 volts. A 360 mah battery can supply a device for 1 hour with a360ma draw. With a draw of 1400ma draw on these atomizers you get:360/1400 = 0.26 hours of life for that charge. Its the same on theVP2, it has a mah rating of 900mah. So 900ma/1400 = 0.64 hours of life.

So to summarize:

VP1 with button on will last ( 60 min x .26) = 15.6 minutes or 936 seconds VP2 with button on will last ( 60 min x .64) = 38.4 minutes or 2304 seconds

Of course you only press the button when you want a hit, right. If a hit is equal to 5 seconds to keep it simple.

VP1 (360mah) will give (936 sec/ 5 sec hits) = 187 hits, before changing battery VP2 (900mah) will give (2304 sec/ 5 sec hits) = 460 hits, before changing battery

For the most part Jeso breaks it down pretty well for everyone. But yes if you use a 510 atomizer the battery life will be shorter. This is because the resistance on the 510 atomizer is much lower than say a Penstyle atomizer (302,304,801 etc) it heats up much faster and uses more power. Either way on a VP2 for example your still going to get well over 4 hours using a 510 atomziers. I usually managed to push around 5 sometimes even 6 depending on how I was vaping.

Dang man, you only get 5-6 hours on a VP2? Don't think I've ever had less than 8.

I'm quite happy with the battery life I get with both my VP2 and Spade, but was curious about how much difference there would be with 510 vs 801/302 atty. Plus, I really struggle everytime any electrical talk is being discussed so I was really trying to understand Jesso's calculations. I followed pretty good, but don't see the jump from saying 4.2 volt to 1400ma. Would really like to understand that.

Which atty do you prefer on the VP2 Chris?

Which atty do you prefer on the VP2 Chris?

Although I usually use the 510 I think the 302 penstyle atomizer works better

Hi Brian, Jeso is using what is called "Ohms Law" a calculation from this law is E(volts)= I(amps)x R(ohms). So in his calculation E= I(1.4 amps)x R(3 ohms), so E = 4.2volts. The 1400ma that you are refering to is the 1.4 amps(converted to miliamps to determine miliamp hours-mah) that was determined from testing the draw of the atty under load with a multimeter.

Did I just confuse you even more?

Actually, I had already found that equation for Ohms Law. I thougth the 1400 ma was 1.4 ams, but wasn't sure. I just got confused by him calculating 4.2v and then jumping to 1400ma. So really, the 4.2V isn't used in any other part of the calc. This did help Jeff, thanks.

OK - so next question - how many amps does 510 draw???

[Brian]

Never mind - I've figured out all the calculations and understand where there 1.4ma comes from. Also got the calcs for the 510 using the same method.

Thanks!
