never used external battery mod before - have questions

[tara81]

Just curious about batteries in mods. I am thinking of buying the sense arrow or eleaf lexicon 235W or the vapresso polar mod 210 W, but I don't understand if two LG HG2 18650 3000mAh batteries are the right batteries for these mods . I also don't understand, how will I know when to recharge my batteries, I shouldn't wait until they are completely drained from what I've read and noticed with my internal mods, they do not allow to vape at around 10-20 percent and say to recharge.

The mods will indicate a visual notice or msg that says batteries are low. No need to worry, they all will do that.
The LG's HE 2 are the ones I think that Mooch recommends. If you haven't already visited the Battery forum, it may be a good time to.

How high of a wattage do you actually plan on using? All of those are dual battery mods and it's not going to matter what batteries you use, you aren't going to get 200+W out of a dual battery mod...at least not safely or at reasonable resistance levels. I believe those batteries are 25A batteries so about 150W (25A * 2 batteries * 3) is about as high as is reasonable to go with them. Even with legit 30A batteries, 180W is going to be the max cap with a dual battery mod. Even if the mod can manage 200+ watts, that is going to only happen at extreme lower limits of resistance of the coils it can support and will likely be overtaxing the battery. I don't know why manufacturers keep insisting on posting specs that really aren't feasible. If anything in the vaping world should be made illegal, it should be false advertising.

A good 20 amp CDR battery is good for a safe 60 watts. The LG HG2 is a good 20 amp 3000 mAh battery, so as you have two of them you are good for 120 watts. The relationship between amp limit and mAh is like a seesaw, the more of one the less of the other you have. 20 amp 3000 mAh like the LG HG2 or the Samsung 30Q provide in my opinion the best balance of these two values.

You do not have to wait until your batteries are completely discharged before you remove them and charge them. Lithium batteries have no memory as such and can be charged at any level.

Yes when the batteries are at a low charge level, they may not be able to deliver their maximum power due to voltage drop in the cell.

Read stuff in the battery section by mooch and some of the other authorities on this matter...

The above advise is half right and the other half applies to a mech and not a regulated mid.


To be safe use major brand batteries Sony, LG, Samsung ect...... Choose the highest CDR rating you can get. As the amp rating is what determine safety.. mah number determine run time. And generally the higher 1 is the lower the other. . So there's a trade off runtime vs safety. Fir a 200 watt regulated mod you should have at least 25 amp rated batteries. . Almost none of these really exist on 18650.

FWIW the amps supplied to the atty may or may not be more than that drawn from the battery.. Mod makers rarely say what they are drawing from the battery.. they sometimes give recommended amp..... which ypu can assume is max draw.

Regulated 2 18650 batteries can supply 200 watts so can 1 battery... they just can't do it at high own rates or for very long. Mah determining time and voltage and amperage capacity the ohm range for full capacity. the main limitation being the circuit boards ability to buck or boost voltage and disapate heat.

All the above information is correct for the most part. As advised, go to the Batteries and Charger sub-forum and /or read Battery Mooch's blog on batteries to educate yourself.



External batteries can seem intimidating to new vapers. That need not be if you educate yourself about battery safety practices. The most important things to know:

1. Just make sure that you always routinely inspect your batteries. Inspect the plastic wraps for holes or tears, and make sure the insulating ring on top of the batteries is intact. Are your battery wraps and insulator rings intact?

2. Buy your batteries from a reputable trusted battery supplier to avoid getting counterfeits or poor quality batteries like rewraps. Avoid buying batteries from Ebay, Amazon, or local vape shops. Trusted battery suppliers:

3. Preferably, buy your batteries from among the "Big Four" battery brands: Lg, Samsung, Sony/murata, panasonic/Sanyo. Avoid buying China-made batteries, often referred to as "rewrappers".

Are You Using a Rewrap (Rebranded) Battery? ​

​

4. Buy a higher quality Li-ion battery charger made by Xtar or Efest. The inexpensive Efest LUC v2 ($20) or more expensive but feature-rich Xtar VP4 ($40) would be my recommendations. Guide to Choosing a Li-ion Battery Charger

Never charge batteries if unattended or while you are sleeping. Charge on a fire resistant surface.​

5. Never carry loose batteries in a pocket or purse where they could come into contact with coins or keys. Protect them in a plastic battery case.

6. My standard lecture on choosing batteries for a regulated mod is as follows:

​

Are you using a single, dual, or triple battery mod? In the interests of keeping things simple:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.​

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.​

WATTAGE PER SINGLE BATTERY on REGULATED MOD:
(Wattage doubles using 2; triples using 3)

Up to 45W:

LG18650HB2 1500mAh 30 amp CDR

LG18650HB4 1500mAh 30 amp CDR

Samsung 18650-20S 2000mah 30 amp CDR

* You don't need a 30 amp battery in a single battery 40 - 90 watt mod if you only vape around 30 watts or less; that would be overkill. All the 30 amp batteries only have 1500 - 2000 mah which have a short battery time per charge. I use the 15 amp Samsung 30Q 3000 mah battery (good for up to 45 watts) vaping at 30 watts and get nearly all day use with a single battery. I'd probably only get about half a day's use if using a 30 amp battery.

The above advise is half right and the other half applies to a mech and not a regulated mid

Specifically which parts of what I said do you think are incorrect?

 

[AngeNZ]

I use the lg hg2 - get fantastic battery life at the massive 15 watts I use - which I think is similar to what you use.

Get some plastic battery cases to store and carry your batteries in.

And just as important - get a quality battery charger.

I am with sonicbomb, I am also curious which half you think only applies to mechs?

I'm stumped by this statement, too. If you disagree on what was stated by another poster, then counter that statement with the facts.

Choose the highest CDR rating you can get. As the amp rating is what determine safety.. Fir a 200 watt regulated mod you should have at least 25 amp rated batteries. . Almost none of these really exist on 18650.

This is actually not completely true. As I stated in my post above, you don't need a 25 - 30 amp battery in a 200 watt regulated mod if you only vape at 30 watts. As long as the battery has enough amps to put out the necessary watts used, you don't need the extra amps. You will get longer run time using a higher mAh battery.

There are actually several 18650 batteries available with 25 amps or more:

Sony 18650VTC5A, 2500 mah 25 amp CDR
Samsung 18650-24S, 2500 mah 25 amp CDR
LG 18650 HD4 2100 mah 25 amp CDR
LG 18650 HD2 2000 mah 25 amp CDR

LG18650HB6 1500mah 30 amp CDR
LG18650HB2 1500mAh 30 amp CDR
LG18650HB4 1500mAh 30 amp CDR
Sony 18650VTC3 1500mAh 30 amp CDR
Samsung 18650-20S 2000mah 30 amp CDR​

I wanted to try the newer mesh coil tanks, thinking of either the falcon tank 0.15 ohms or fire pro double or triple coil at 0.15 ohms. I'm guessing I would need 60-100 watts?

Thank you so much everyone for explaining things to me I think the lg2 3000 mah would be ok for this.

The only Canadian online vendor I could find with these batteries are dashvapes.com, but I don't know if they are reliable? Most of the other vendors don't ship batteries across border , or the ones I checked.

As stated by everyone above, as far as batteries are concerned, if using a regulated (electronic mod with adjustable wattage), coil resistance is irrelevant. What is relevant is the wattage setting that you will be using. With the Lg HG2 20A 3000mah batteries you will be good for up to 120 watts when using 2 batteries.

Coils will have a recommended wattage range to fire the coils (usually printed on the coil itself). This is a "recommendation" but is not set in stone. You can safely use a lower or higher wattage setting. Use the wattage setting that best suits your vaping preference. You may need to adjust the airflow of the tank to find your "sweet spot".

Dashvapes has an excellent reputation, especially for ensuring the authenticity of their products. When I was looking for a Canadian battery supplier, they told me they get their batteries from Illumn, which is one of the recommended vendors listed above. While I can't guarantee their veracity, I'm inclined to think they're honest. The batteries I've purchased there have always behaved as expected.

If you'd really rather stick with one of the recommended vendors above, check through all their sites because I'm pretty sure a few of them will ship to Canada. Many people have had no problems at all getting batteries from the US, although a few others have had trouble with customs. Personally, I prefer to let Dashvapes deal with the international shipping.
