<br />
The guys here <a href="http://www.e-cigarette-forum.com/forum/vamo/355592-vamo-battery-thread-16.html">http://www.e-cigarette-forum.com/forum/vamo/355592-vamo-battery-thread-16.html</a> were wondering about the performance of the VAMO e-cig with 1 28650 battery or with 2 18350 stacked.</div>
<div style="text-align: center;">
I have some Efest batteries from the last test and awsum140 measured some current consumptions for me.</div>
<div style="text-align: center;">
So we created a "vape" simulation with both batteries, it draws the same power that the Vamo uses during vaping for 5 seconds and rests for 25 seconds. All that to simulate the actions of the user while using it. It's like chain vaping until the battery reaches the 3.3 cut off voltage. (we didn't use the 2.750V cut off since users tend to recharge the batteries at 3.3V)</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
The 18650 gave us 250 puffs both times. Continuous vaping for 2 hours</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
The stacked 18350 gave us 477 puffs (?!?) the first time and 479 the second time. Continuous vaping for 4 hours</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
Seems like using two stacked batteries performs a lot better.</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
Get the files here:</div>

<br />
<br />
Note: the stacked 18350 batteries ran cooler than the 18650 mainly because the mod draws 1.02A at 7W so there was not so much stressing.</div>

<div style="text-align: center;">
Here is an interesting battery. This is not a high drain (IMR or Li-Mn if you prefer) battery but it's protected for over currents and temperature.</div>
<div style="text-align: center;">
The test was performed with a 1A charge current as Fenix recommends but i didn't used the 3V cut off but the normal 2.75V.</div>
<div style="text-align: center;">
Take a look on the temperature of this unit. On 1.92C (5A) Discharge the battery has reached 60 Celcius and the analyzer paused to let the battery cool down. The protection didn't kick in so i guess it goes further but no need to risk it.</div>
<div style="text-align: center;">
It's a neat battery for flashlights anyway, in most cases you do not need to discharge at higher C ratings.</div>

This battery is a winner. Infact it performs almost as the 2250mAh version.</div>

Excellent batteries, performed 102.0%!!!!!</div>
<div style="text-align: center;">
Remember anything above 80% is fine but this was amazing.</div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
Usually the first discharge is out of the box and the batteries perform a little lower, after charging with the analyzer during the routine the battery is more refreshed and performs almost full.</div>

I also have to thank Ms Anita Gross from Eneloop Sales & marketing division who sent me samples of their batteries. Excellent customer service (pretty fast too) and they were happy to answer all my questions.</div>

This battery straight out of the box gave me 91% and then after a charge it gave me 97.9%. I'm pretty sure if cycled one or two times more it will reach 100% or more but i am having the analyzer testing two AAA eneloops right now so i may test later.</div>

Samsung has this model which has a 18A discharge rate, At 3.33C (5Amps) it performs similar to the panasonic CGR18650CH but only for 17 minutes. It performs with around 96-93% capacity and the temperature is quite low (mostly because of the high discharge rate it didn't bother much). Here is some data at 5A loads</div>

<div>
The battery gave me 2.103Ah for 25 minutes continuously, note the temperature rise, it has reached around 36 Celcius.</div>
<div>
Then there is a 10 minute rest, the temperature starts to fall now.</div>
<div>
Then there is a pre-qualify charge which finishes in a few seconds and the main charge starts.<br />

This battery has been rated around 92-93% capacity when discharged at 5Amps and 97 to 93% at 1C which seems to be great (i got 95% with a different battery at 5A). Anything above 80% seems to be OK but i prefer to get the most. After that the analyzer charges the battery up to 30% for storage mostly. Soon i'll be able to discharge at maximum rates (10A for the panasonic.) Also take a note on the temperature and how it varies depending on the current.</div>
