Is these safe volts/is my battery working as intented?

[Dislokaatio]

So, i do have eVic-VTC Mini with Uwell Crown (version 1) tank,using 0,5ohm coils. Also i have Samsung inr18650-30q battery in it. I was wondering, is it safe for battery to use 50W in power mode? It says volts are 5,10V and amp is roughly 09,5A when i'm firing it.

I've heard that ampers should be fine with that battery(?) at ~9A, but i was just wondering, are the volts?

So far i haven't noticed any problems using those settings, exept battery drains fairly fast (not instantly, i have pretty good amount of time to use it with 50w) using 50w compaired to like 40w (at 40w, volts are 4.56V and ampers ~08.5A), but my mod is starting to say "weak battery" when battery level is little bit higher than half, then dropping watts to 40-45w removes that "warning" for awhile and occurs again at ~3/8 battery power left, and so on.

This didn't happen when i used different tank, TRON-S, but also i didn't have to use as high as 40-50w with that like i have to with Crown. It was more like 20-25w with that tank if i remember correctly.

Sometimes i just continue using 50W even when mod says weak battery, vapor is just slightly cooler then, but i haven't noticed anything else really, battery doesn't really heat up abnormally or anything.

Also the battery should be authentic, it's purchased from local shop in Finland, and you cannot really find pirate stuff in markets here

I don't really understand anything about ampers or voltages, so i just want to be sure it's safe, even when there haven't occured any real problems so far.

Thanks to anyone who takes time to answer this, much appreciated!

That is usually the sign of a battery nearing the end of its useful life. The 30Q is a legitimate 3000mah battery with a safe constant discharge rate of 20A. If your mod is warning you about a weak battery, it's likely that the mod is detecting that the battery can no longer provide the amperage needed to supply 50w of power.

An inexact but useful rule of thumb for a regulated device is Watts / 3 = Amps needed. 50W / 3 = 16.6A, something that battery should be able to do in new condition. But as the battery ages the ability to perform up to spec drops.

Your battery may well need replacing. My advice is get at least two batteries for every single battery mod and at least four for every two battery mod. A deeper battery rotation means fewer charge cycles per battery and longer life.

Hey, thx for the answer! I have some questions:

So first, why my mod then says at 50w 9,5 ampers, if it should be 16,6? And secondly, do you have any idea about that volts, is those on safe range?

Also sorry, i've only vaped about a year on-off, so i don't really know that much =)

The amp displayed on the screen is a meaningless output amp from 'chip' to delivery device, it has nothing to do with input amps from cell(s) to 'chip'.

The 'chip' pulls amps from the cell to boost voltage, the voltage displayed on the screen is also output, the battery cannot supply more than 4.2v fully charged, nominal 3.7v, low voltage cutoff is power device dependent/specific.

What does the mod report for voltage when the amp reading is lower than expected? Voltage sag could account for the amp readings you are seeing.

As Topwater Elvis said, those readings aren't from the battery. They are readings from the electronics as it tries to create the 50W vape level you have dialed in. It still sounds like battery voltage sag. Try some new cells. 30Q is fine, but you need to know they are legitimate and not knockoffs. Either way, it looks like your battery isn't up to the task. Generally, a 20A cell is pretty much maxed out at 60W vape levels.

I might have some answers!

[edit: didn't see the other two posts before finishing my reply. "WE" might, that is.]

That current reading is what the chip in your mod is delivering to the atomizer. It's not the same as what the chip is drawing from the battery. That's "nice to know" type information, but it's not useful in determining whether your battery is capable of performing safely in your device.

Also sorry, i've only vaped about a year on-off, so i don't really know that much =)

You knew enough to ask a question and around here, that's good enough.

Great answers already!

If you are finding that you like to vape at the upper end of that single battery mod, it might be time to consider a dual battery mod alternate.

Continuing to vape at 50w when the mod is reading low battery means you are not actually vape at the set output. When regulated mod's display low battery when vaping, the actual output is reduced. Some mod's display the reduced output, provided you can see/read the display during vape.

Stepping up to more batteries would greatly enhance daily vape time, and allow you to explore optional builds and vape experience.
