Aga-T2+ poor results- HELP!

[dam718]

Yah, my quick and dirty test was popping the bottom cap and trying my multimeter in amp mode, connecting the battery neg to the VAMO case. I got 4.76 amps. Obviously there's efficiency loss, so then I popped the AGA off the top and pushed the case of the AGA against the vamo case and did my best to connect the pos posts with the multimeter in amp mode...got 2.75 amps or something.

I want to rig up a setup to let me hook the AGA and VAMO together with leads in between that I can meter from....but the other thing nagging at me is I know the VAMO is using PWM, and I know that PWM is often misread by digital multimeters.

So hell if I know. Seems dumb to state 5 amp limit if it's impossible to hit with the 15 watt limit, (15 watts at 5 amps is 3 volts, which would necessitate a 0.6 ohm coil...which the vamo obviously won't fire), but when in China....

What battery configuration are you using with the Vamo? From what I have seen, it cannot hit its amp limits using a single battery (18350 or 18650), but with stacked 18350's it will fire that low res coil at 6 Volts all day long... Jumping way past its 15W "limit"

I haven't done that myself, only ran it with a single 18650... May be worth a try.

That's a pretty hot setup though... Something is surely going to explode... LoL Be careful!

I'll let you know. I have a pair of 18350s on the way. (I figured, even if it was working well with the 18650 I have, it's far more efficient to buck voltage down from 7.4 to 6 than it is to boost from 3.7 to 6. So I should get better efficiency from 18350s...of course they are lower mAh, so we'll see what's better). I plan on rigging up my test method with the multimeter to see what the vamo is actually pushing, assuming I can trust what the digital multimeter reads out when it's running in VV mode.

Don't you mean 0.8 ohms?

yes 0.8 ohms, not sure why i do that, is 0.08 different to 0.8?

yes, that would be smoking. let me know how it performs

 

[StaircaseWit]

yes 0.8 ohms, not sure why i do that, is 0.08 different to 0.8?

Yes, by a factor of 10.

0.8 ohms = 8/10 of one ohm.

0.08 ohms = 8/100 of one ohm.

I just wanted to make sure we weren't talking about a coil with an *extremely* low resistance.

thanks, i think i mean 0.8, 2 clicks under 1 ohm, that would be exxxxtreme vaping at 8/100 of 1 ohm.

see for me , with the provari a 5 amp limit would be great. i love a 4 wrap with 28g, giving me a resistance of about 0.08ohms, i would love to vape this at maybe 14 watts, but a 0.08 coil is amped out at around 10 watts, but if the provari had a 5 amp limit, i could vape my 0.08 ohm coil @ 3.5v to be at 15watts. but for now the max wattage, max amps on the provari equals about a 1.2 ohm coil at around 4.1volts, although its a great vape, i do prefer around 12 to 13 watts, i have found a 1.0 to 1.1 ohm at 3.6 ish to be my sweet spot. but i still would like to try a 0.08 coil at 15 watts, but that is still way under 4 volts, i seem to prefer high watts at low volts, it just seems to me when you vape hi watts and hi volts the vape suffers somehow.

You need a good mechanical mod with high drain batteries. They are perfect for how you are wanting to vape.

 

[OttoBahn]

You need a good mechanical mod with high drain batteries.

Genuinely curious why..

Why?:

1. A mechanical mod (vs a vv)
2. A high-drain battery (vs, non)

Reason - I've heard it said often, but never a clear reason(s) as to why (and the advantages/disadvantages of either/both - when using an RBA)..

 

[eHuman]

Mech mod = no electronics to fry, combined with HD battery = .8Ω atty vaping capability.
VW MODs won't fire an atty below 1.2Ω, but they need to be run with HD batteries too.

i have both, i do own a mechanical mod as well as a provari v-2, love them both, but like the provari better, with the provari i can run a 0.8 ohm coil with no problems, but usually opt for a 1.0 to 1.1 for you can obtain a higher wattage and amps with the 1.1 coil compares to the 08 coil on the provari. the mechanical mod is also great, but dont like the drop off in vaper production after a while, waiting for a 13 watt kick, then i will be set. and always use aw imr's, but heard the mnke batterys may be better for lower resistances, what do you think?

 

[eHuman]

I have only used the EH and AW IMRs. I love both my mech and my ZMax for different reasons. I haven't used a kick, I can't justify the cost, I wrap coils based on the 3.7 range for the mech so I get good vape for 85% of the battery life then I swap batts. I remember you talking about the short drop off on your battery, mine doesn't behave like that.

The voltage drop does kinda suck with unregulated mods, but you can get some crazy wattage going. I haven't really looked into those batts, so I can't answer about them. Have you tried twisting your wire for a coil? I'd be curious how twisted 32g would compare to your 28g coils. Here is Todd doing a bit with them:

no i have never tried twisting wires, have seen that video before and was meaning on giving it a go, but just never got around to it. you know the mechanical mod i have is just average, its an omega, i guess its the silver bullets brother. it just has maybe chrome contacts, so its probably not to efficient. once i get(or if i get) my caravela in oct (unless i win the caravela lottery) i will try some of that crazy wattage. i will get some 26g (i think thats the lowest i have seen) and do a 3 or 4 wrap, with some ohms about 0.5 to 0.7 just to see. but for now i am really loving 28g/ 1.0 to 1.1 ohms at around 3.6 volts. for the most part i set up all my gennys this way so i can vape them on both a mechanical and the provari. every now and again i do a 0.8 to 0.9 on the mechanical mod to 15 to 16 watts

its probably my omega, with just chrome contacts it might be why. once i get the caravela with some brass contacts i am sure it would perform way better, and i probably be using it way more than the provari

I hope someone has seen this but I have to ask. Just got a aga t+ using ss 400 and 32 wire. Meter reads 1.5 to 1.6
Vamo reads 0.8. After adjusting coil and wick got it to read 1.7 on vamo. Now getting 02 code and vamo shuts off. New to the RBA and getting frustrated.

I'm no expert in these matters since a couple of RBAs are on the way I will be trying out for the first time, but 2 things do come to mind.

1. Make sure your wire contact is good, ie. no looseness, coil wires not touching each other.

2. The SS mesh not shorting out by touching the bottom of the tank.

 

[mwhitley]

Going to double check both. Thanks for the reply.

what voltage do you have it set to?

 

[mwhitley]

I was using the vw at 5.5w. But the problem is when I check the ohms on the vamo it's saying 0.8 ohms. Then flashes 02 code and shuts off.

 

[shortyjacobs]

Vamo does not have error codes. N02 means rms mode, N01 means avg mode. They are modes of voltage delivery, you hold either + or - for 10 sec to switch. You want mode 02. Don't hold your + key so long when reading ohms.

As for low ohms, you have a short. Fiddle with the coils while pulsing power, use an unregulated mod if need be. You'll get it.

Also, switch to variable voltage and set voltage at 3 while until you get the coil running right.
