My ego battery lasts longer than my18350's

[damselle]

I bought a new mini vtube that came with an 18350 batt. It only lasted for four hours. The company sent me a new one, but the new one also only lasts about four hours. Off the charger, the battery power reads 4.2...I'm assuming this means that I can only get 4.2 volts from this battery?

Is there an alternative?

Well, here's a guess.

1) That brand of 18350 (whatever it is) may not be the top performer.
2) The eGo is modulated to 3.4 volts. It actually "pulses" the electricity and kind of cuts it down. Whereas a vv APV/mod has more circuitry for the vv part and may lose some efficiency too.

So for #2, you'd have to measure total watts expended over time at the 3.4 volts to compare. Also I'm assuming you used the same atty/carto on each as a test.

Alternatives.
1) Try different brand 18350 to see if it matters. (EDIT: see my next post below)
2) Up the ohms a bit on the atty/carto for the vtube... and use higher voltage. Higher voltage is more efficient.
3) Get the longer extension for the vtube and use a bigger battery. Sometimes you may trade a bit of efficiency for options/convenience. The bigger battery will compensate.

1) Try different brand 18350 to see if it matters.
2) Up the ohms a bit on the atty/carto for the vtube since it's probably hotter anyway (at least for the start)

EDIT: Editing for lavatube/vtube....

No, I didn't use the same atty. didn't realize that made a diff...

Can you make a recommendation on a good brand?

I edited, so see my 1st post (you quoted the one where I didn't realize a vtube was a LT type of vv APV).

The ohms matter because they control how fast it uses electricity at a given voltage (like 100 watt bulbs using more electricty than 60 watt bulbs).

That's a good question on batteries.... I'd 1st check that it is a protected battery (unless the vtube has a protection circuit built in) for the 18650 and then .... IDK. There are some real battery smart people on here, wait a bit and you'll get a more informed answer than I can give you. I just keep 3 sets of an average reputable battery charged for my box "mods'. IDK about how one brand performs 5% better than another! lol. So I don't really bother following those conversation. Other do, though. So hang on!

The site says
* Uses one 18650 (1600mah) or 18350 (700mah) flat top high drain battery

The "High Drain" battery would be like an AW IMR battery. They are well reviewed. However, note that high drain batteries store less charge (but release it faster) due to different battery chemistry. <-- (as of this date). So that explains the difference too. If it says use high drain for the small battery, use flat top high drain.... it requires it.

I assume that also means that it has a boost circuit. Although not as efficient, they allow more than 4.2 volts. I could be wrong on this tho... there's so many models and features.

You could try 5 volts and 3.1 ohm stuff. May extend the life a bit. I just keep a stack of charged batteries for my mods. Easy to swap them out.

That is perfectly normal for an 18350 mini battery

Off the charger, the battery power reads 4.2...I'm assuming this means that I can only get 4.2 volts from this battery?

Is there an alternative?

4.2 volts is fully charged and never let it go over, when charging. However, you can turn up your mini lava tube to a higher voltage, that is what it is designed for. 4.2 fully charged battery. Lava tube can boost it to 6 volts if you have the right cartomizer/atomizer.

 

[damselle]

ok, thank you Conan. maybe I need two.

 

[njgeek]

Make sure you are using standard resistance cartomizers (or whatever), 2.8ohm and up. The point of a VV is to up your voltage to match the higher resistance; high volts at high resistance has more power in watts and less battery draw in amps compared to a low resistance atomizer on a low voltage device.

But, the 18350s aren't powerhouses. I have a Provari Mini with an extension cap, the 18350s last about 4 hours, the 18490s last about 6-7, and my 1600mah 18650 in a VTube lasts a good 9-11 hours.

 

[njgeek]

Definitely have 2-3 so you can have a decent rotation going.

damselle,

Get yourself some AW IMR 18350's there gonna be your best 18350 Batt

I'd say get reputable battery, even a few of them, or switch to the 18650.
