35a Battery

Hi

I'm using Samsung 21700 T40 batteries.
Trying to figure out..
Is it best to charge a battery when it's discharged or nearly discharged?

I like to keep things simple with a routine of charging once a day, but then the battery will be set to charge even when there's 15-30% power left.

Is that bad for the battery?  

Hello—am I calculating correctly? I now have a Jackaroo mod that takes a 21700 so I ordered the Molicel 21700 P42A. Someone on the forum helped me out once before and here is the calculation I used. I figured in at 30 watts –I am usually between 23 and 30 watts

30 watts/3.2 battery cut-off voltage/.9 - 90% efficiency = 10.4 Amps
(30)(3.2)(.9) ---max wattage to be used is 86.4

What about my 2 battery mod --is that calculation for each battery. For example, I ordered a Geekvape Aegis X that takes 2 batteries so If I had that same calculation would my wattage be 86.4 per battery?  

Hello All,

Does anyone know which 18650 battery would last the longest when vaping at 13 watts? I have listed some below but any not listed recommendations are welcome as well.
(PS please don't respond with battery safety information or suggestions for me to look at mooch ratings)
Also, does anyone know if the vendors in the last 3 below links are reliable?

Thanks!

I purchased a Vaporesso Swag II.
It comes with two coils. One of them is a
0.15ohm GT4 Meshed Coil - rated for 50-75W, best 60-70W I liked how it tastes.

The Swag uses one battery only.
Is it safe to use Samsung 30Q 15A batteries and run the Swag at 65W?
If not, what battery would your recommend in order to use it safely at that wattage?

I’m asking because I have always considered the “rule”: maximum W = 3XA  

I am looking for a dual 21700 mod. The available ones, I probably will buy but, there aren't many to choose from. There are several single 21700 mods. My question is how long (on average) will a single battery mod charge last (I know this question is subjective). I vape around 65 watts, most of the ones I have seen online are rated 100 watts. I do not want to leave home and my mod die out because it was a single battery mod. I know I could carry a spare charged battery around, I just do not want to have to. Thanks  

Hi
I'm usually vaping at just 14 watt (mouth to lung, nothing heavy).

Now I'm soon getting a new mod that takes 21700 batteries, so I'm searching for the best batteries without spending too much or too little.
(aiming for Samsung, LG or Sony, to be safe)

I see some batteries hold 5000 mah, like the Samsung 50E (cyan).
But it only has about 10 amp discharge rate.
So less than half than "regular" 4000 mah batteries for example.

Is 10 amp more than enough for vaping at just 14 watts, or should I find a more "high-drain" battery?
I want to be safe and avoid risks or heat.  

Hi
I just got a Xtar VC2s charger for my 21700 batteries (Samsung 40T).
Chose that charger also because it "charges at safe low current".

When it charges 2 batteries, it's at about 1000 mAh for each battery. All good.
But when charging only one battery, it charges it at 2000 mAh. Hmm?

I assume 2000 mAh is still "safe".. But won't that reduce lifespan on the battery?

The charger manual says "when the power supply is insufficient, the charger will reduce the charge current correspondingly".
So maybe I should get a usb power supply with like 1000 mAh output?

I will only be charging one battery at a time, and prefer charging slowly if that gives more safety and lifespan.

But I don't know if charging at 2000 mAh is really an issue..  

Hey vapers.

Wanted to start a thread for discussing the DNA 250c chip, all of its features, options, performance, etc.

I started this threat to not only begin a discussion about the DNA 250c chip, but to also share something with new users that may prolong the life of their batteries.

With battery life, I mean the number of charge cycles it'll take before noticeable decline in performance, and general battery health. My advice of setting the cutoff voltage higher will shorten actual run time.

I've noticed that 'out of the box' the DNA 250c is set to soft cutoff the battery at 2.75 volts.
This results in a 3.00 volt reading on my charger when I get the batteries out.

This, in the opinion of many, is too low for batteries to go, and especially to remain there for any length of time.

So, I want to share with you how to change the settings so that your mod will cease using the battery at 3.1 volts, which results in your battery resting at a healthier 3.35 volts.

Here's how :


​
Click the image for a larger view.

Basically, in Escribe, go to Options, then User Interface, then Advanced. Select Mod tab, and then Battery tab. There you will see the 2.75 volt setting, and you should change that to 3.1 volts. Upload setting to device, and you're done.

The DNA 250c comes with a wide array of options and customized performance.

I'd love for people to chime in and share their tips and expertise with Escribe and the DNA 250c chip.

So let's hear t !

P.S. When will Evolv update Escribe to list 21700 batteries ?

Hi everyone,
Hope your all having a great weekend! Hopefully someone can help me figure out any good canadian or American reputable vendors for 18650 batteries for my arrow sense mod. Out of all the vendors listed in the battery thread, only one had the batteries I wanted, but it was in the US and would cost over $50 for shipping. Hoping to find shipping for $20-30 canadian instead. I am particularly interested in the batteries on the forums listed as tested by mooch in a stickier post. Or Sony battery with 2500 mah , I like to vape with two 18650 batteries at 60-80 watts.  

I've been using only twin-18650 mods for some time, and before the shipping ban came into effect, I bought a backup of my most-used mod (a Geekvape Aegis X), but since the 100W single 21700 / 18650 Voopoo Drag X Plus was only $35, I also picked up one of them as another backup.

I vape exclusively on RDA's, typically with a 3mm dual coil twisted build with 24 or 26 gauge Kanthal or nichrome-80. 5 or 6 wraps with 24 gauge, 6-8 wraps with 26 gauge. I typically vape these between 90 and 110 watts.

I did not expect to get a 'true' 90-100 watts out of the Drag X, so I set a target of around 60 watts. I mounted a 3mm dual coil twisted 28 gauge build with 6 wraps, which on my Aegis X vapes great at 60 watts, and very good at 50 watts. It measures at 0.45 ohms.

But on the Drag at 60 watts, it only vapes at what feels like 30 watts on my Aegis. Setting it higher makes no difference either, it seems to 'top out' at ~30 watts regardless of the setting. 60 watts @ 0.45 ohms is only around 11 amps, so I doubt I'm hitting an amperage limit.

I am using 18650 batteries (VTC5A), and it is about time to replace them, as I am only getting around 70% the battery life as I did when new. I will be picking up some 21700 batteries at the same time, which hopefully help with things on the Voopoo.

Does anybody have any good experiences with ~60 watt builds on a Drag X Plus?
