The VAMO battery thread

[caged]

To get this thread back on topic.......

The Vamo is struggling at 9 watts with a single 18350 using a 3 ohm Cisco 306. The battery dropped from 4.2 volts to 4 volts in very little time then it started tripping protection circuitry. 8.5 watts is working so far with the battery reading 4 volts.

Edit: Spoke too soon. 8.5 watts is tripping the protection circuitry, though not as bad. Stacked 18350s have no problem.

What kind of 18350?

NOTE: Resistance does change with heat.

18350 - 700 mAh?

4 Volts on 3 Ohm Atty pulls 1.33 Amps (1333 mA) - no problem - just half an hours useage based on 700mA for 1 hour (700 mAh)

Based on Watts over Volts x Amps (W over V x I) 4 volts on a 3 Ohm atty should give (4 volts x 1.33 Amps) 5.32 Watts.

Something is wrong somewhere.

Efest (800 mAH).

I'm using AW IMR 700 at all watts no problem except short battery life for my way of vaping. 8.5 watts and 1.7 ohm resistance and constant all day vaping with minor breaks.

According to this video review Eagle VV & VW Mod Review (aka the Vamo) - YouTube to get optimal battery performance the atomizer resistance needs to be in the range of 3 ohms, if less the Vamo won't achieve the set voltage and the device operates at a voltage deficit. The voltage deficit is very high if using a LR atty < 2 ohms. The reviewer does state that the voltage deficit is not specific to the Vamo and is common to all devices when LR attys are used.

My coils are in the 4 ohm range and I get very good results from the Vamo in VW rms mode. I think I get better performance using the stacked battery configuration in comparison to a single 18650.

Technically yes, but in reality, not so much. At 4.5v set value into 1.5 ohms, it is putting out 4.48 volts, which is pretty close. That is 13.5 watts(the VAMO has a max of 15).....who really hits a 1.5 atty that hard except for charting purposes?

Just sayin...

I have been using a single efest IMR 18350 in mine at work. If I keep single coil 2 ohm cartos on it, I get about 6 hours at 7 watts before needing to replace the battery. I tried a 1.5 ohm dual coil at 14 watts and it kills the battery within an hour so I do not use them at work.

When I stack the 2 18350s I can run anything on it for over a day. I have not used an 18650.

I just brought the vamo from vaporbreak can some one suggest me a website were i can get good charger and batteries.
I never used any mods i have a ego t , i am new to this

Thanks

RTD Vapor
Is my go to for batteries and chargers.

RTD is great ... Orbtronics can sometimes be cheaper ... Steammonkey is selling his Panasonics even cheaper than orbtronics but he doesn't carry the charger.

 

[Underwhelmed]

Here's my criteria, YMMV.

RTD takes PayPal, have just about every type of battery you might need, and they ship super fast.

When I wanted to order from Orbtronics a few months ago, they had all their inventory zeroed out and when I messaged them to ask what was up they said it was because they were in Europe. They did contact me a few weeks ago to tell me they were back.

I've never ordered from Steammonkey. I wonder if he allows local pick-ups since I'm just 40 minutes from Ft. Worth. If so, I might get a couple more Panasonics from him.

I'd be willing to bet he might let you pick them up but I believe he offers free shipping on those Panasonics.

 

[Underwhelmed]

That is a good price on them, especially with free shipping.

I have just used the atty resistance check on two separate Vamo's and it varied between these two configurations using the same atty.

18650 AW IMR gave a reading of 1.5 ohms
18350 AW IMR's (stacked pair) gave a reading of 1.7 ohms

Has anyone else has this problem ?

PBusardo noted that in his review, made the wattage output just a hair off as well. Some of them are a tenth or two off.

Thanks a lot guys for pointing me in the right direction, i am so glad i found this forum.
Thanks again

I currently have the ego-t with smoke tech daul caoil 1.5 ohms cartomizers, if i use them on the vamo what voltage and wattage should i use. Ignore my question if it make no sense.

it is mentioned that its a flat top would that matter?

I use the same carto deepdeep.

With an 18650 - start around 3.4 volts.

With 2 x 18350 (stacked) - start at 3.0 volts. (they are vicious with 1,5 ohm carto's)

Adjust as necessary, depending on ejuice and preference.
