Confused about batterys, think i am exceeding battery capability...

[Justin Proctor]

So looking into mech mods...Before i went near that area started doing some research and it appears even with my regular VAMO i could be exceeding what it can produce. Just trying to clear it up incase i am misreading something...

So atm i am running a 1.5ohm coil on these batteries. I am running at 6v (Vamo max). When i use ohm law calc and insert 6v and 1.5 ohm coil it says i am using 4 amps which i know is less than half the AMP draw so i should be safe there and it says i am drawing 24w. Should i be concerned about the high watts.

The only reason i mention this is because if i turn this around and run at 15w (Vamo max) and a 1.5 ohm coil it says i need 4.7v. And my battery is only rated for 4.25v.

Am i confusing the issue ? Am i safe using it in voltage mode. I had always just assumed that running at max 6v or 15w was going to give me the same result on vapor production and throat hit. But maybe i am wrong.

Your fine.

The max the VAMO is going to be able to send to a 1.5Ω coil is about 4.7 volts, so there is no need to set the VAMO higher than that.

You essentially answered your own question when you plugged in the numbers using the VAMO's maximum wattage. Even tho when you switch to voltage mode, you can toggle up to 6V, that's not what is going to fire.

It is a regulated device, and will not perform outside of it's limitations.

4.2V is the charging capacity of your battery. Where you don't want to exceed that number is when your charging your battery.

When using in a mech, fresh off the charger your battery is going to output 4.2V, and then slowly drain down from there.

I fully understand what you are saying in terms of running it at 15w will only send 4.7v. But are you also saying that if i run the VAMO in volts mode there should be no difference in running it at 4.7v instead of 6v ? This doesnt seem right....I mean as long as i am not sending more than 10Amps should it not fire at 6. Your comment has left me more confused

Also i feel like i am getting more vapor running at 6 rather than 4.7....Is it all in my head ?

 

[Justin Proctor]

Think i have just figured it out....Are you saying this is nothing to do with the batteries....Is it simply because of the VAMO....

If i was for example using a 3ohm coil and tried to run it at 15w....it comes out at 6.7v....Therefore i would only get 6v because that is what the vamo is limited to ?

If i am understanding this right i have been exceeding the limitions of the VAMO and not the limitations of the battery....So i have caused no damage to the batteries ?

Yes.

It doesn't matter that your battery is rated for 10 amps, it is a regulated device that will not exceed it's design limitations.

YES!

lol. These are the things that i want to understand fully before looking into mods. I guess looking into my protected device isnt exactly the best way to learn anything about the batteries

I only mention the batteries because one of mine is beginning to show some wear on the outer shell. I would stop using it all together but i tend to run my battery down to 3.9-3.8v and then stick it on the charger and replace with the full charged on. Just dont feel like i am getting a good hit when running at less than 3.8v...Pretty sure both batteries are on their way out because atm 4.2 to 3.9 is only taking about an hour.




Still safe to use or is it dangerous looking ? Only charge that one when i am in the house to be safe atm.

From what I could find the Vamo, at least the V3 is will give you up to 5 amps. As long as your battery can support 5 amps you should be good. There is some talk though about the booting technology where it will "boost" the amps of the battery need to get it where you set it. Ongoing debate on that with no conclusions that I could find.

Make sure you have good batteries and all should be good. Know your batteries discharge rates and charging rates. Heck know the cutoffs too.

The vamo has an amp limit of 3.5 amps. Regardless of what mode you run in, that's the upper end of the amount of current flow you will get. If you run a combo that would calculate higher amp draw, then you only get the voltage up to 3.5 amps, regardless of the setting.

I can't tell in the pic, as long as the wrapping isn't ripped your fine.

Don't quote me on this; but I'm fairly sure that batteries drain down to 3.8V-3.7V rather quickly, but will hang around 3.7 for awhile before going downhill from there. The less far you drain your batteries down between charging cycles, the longer your batteries lifespan will be. Honestly though, big deal? Just use your batteries so you can vape, man. Batteries are inexpensive. You could be using your batteries much longer than you currently are. Your VAMO will cut-off and stop using the battery when it drains down to 3.5V, which is fine.

Your being very cautious, which is great, but there is no need to be so overly-cautious that you are not getting enjoyment/use out of your batteries!

A big part of the appeal with a regulated device is... well it does most of the technical stuff for you. Your VAMO will not over discharge your battery, so feel free to use it until it displays "LO" indicating that the battery needs to be charged. It will not fire a short. It will not power up if you put your battery in backwards. VW is the best mode for a VAMO, because it will measure the resistance and automatically adjust the voltage to accomplish your set wattage (in your case looks like you are digging 15W).

The VAMO claims to have a 5 Amp limit, but that's not how it operates. No matter the resistance of the coil you put on it, the VAMO will not exceed 15 watts of power. It won't fire anything below 1.2Ω, so I'm not sure where the 5 Amp specs come from but it doesn't matter. If you want to crank anything on a VAMO as high as it can get, just go to wattage mode and crank it to 15W. That's the limit.

I have heard that it hands around the 3.7 mark for a while....But i could be sitting not getting a satisfying vape for an hour....Replace the battery with a full one and i get a nice hit off it....So it seems the batteries i am using cannot give me 4.7v when they are down to 3.7.

So much for marketing crap. This I did not know. Thanks.
