Going From A $100+ 21700 Mod To A Simple Aio Pod..

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?  

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  

I ordered a SXmini SL class with the sx485j chip and it recommends a 35a battery. I only use .15ohm coils at 60 watts so I should be good with a samsung 18650-35E right? Going to buy 21700 batteries once these start losing their charge because I just got them recently..  

I've been looking at this kit because it seems simple and has more power than my Aspire Tigon. Does anyone own one and what do you think of it?
Hopefully this is posted in the right place.
Any and all replies are appreciated.
Thank you.  

Or maybe even a heretic, or a blasphemer?
I like mini tanks and small batteries. My favorite setups are mini protank version 1 clones with 650mah basic ego style batteries. Stainless steel finish, no funky colors or designs. Single bottom coil on the tanks, no air flow controls. Standard voltage batteries, no twisty things on the bottom, no usb passthrough, no digital displays, just a battery. I like the ego style because the protruding button is easier to find and helps keep them from rolling around. The lack of features I don't need means the batteries are small. I like small, sleek, simple.

I have a nice big fancy Smok vv/vw battery. If I cut my juice in half with VG I can blow some massive clouds without knocking myself out. I found this to be mildly amusing for a short period of time. I also found out that with my regular mix when I dialed around for the "sweet spot" I ended up at 3.7 volts...

The mini tanks don't hold a day's worth of juice, and the 650mah batteries don't last all day. So what? Tank gets low, twist it off and pop another on. Battery light flashes, same thing. I've got a battered old EGO case from my first starter kit, it holds four tanks and batteries and a bottle of juice with room to spare.

I got my first mini pro tank from a vape shop. I just assumed it was a Kanger, but there was no mention of Kangertech anywhere on the packaging or tank. Whatever, I really liked it. I figured the real deal would be even better so I ordered one online. Kanger had discontinued the version 1, so I bought the "new, improved" version 2. It was good, but I liked the clone version 1 better. The clone tanks are polycarbonate rather than pyrex, but I don't vape plastic eating flavors, so that's a non-issue.

Now I'm not knocking all the cloud chasing, coil winding, wick trimming gear heads that seem to dominate these forums, but if there's anybody else out there who enjoys vaping with a nice, simple, inexpensive setup, I'd like to hear from you.  

Since I started vaping over a decade ago I've been using Pila chargers and hadn't seen a reason to buy anything else.

I'm now looking at a mod that ideally wants a 21700. Will it fit into the Pila? If not, what's a good charger to use with it?  

So, I recently purchased the Gaur-21 with the Valyrian II Pro, and the mod is 21700 and 18650 compatible. I was curious as to the benefits of the 21700 batteries, because I’ve only used 18650s.  

So I have been vaping since 2010, and still use my original REO's with a RBA. Back in the day, I would gift a new vaper with an ego to get them started because it was cheap, simple, and had just enough battery life to not have to recharge constantly. Also, it was easy to switch out attys and try different flavors without worrying about leaky tanks.

I met a young man who smokes 2 packs a day menthol, and is really open to switching. I have a pretty good supply of various flavors of 24mg 80pg/20vg liquid. What can I get him that will make it easy for him to start now (and isn't beyond my ability to help)?  

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..
