Battery question

[Adrian581]

hey just bought a Panasonic NCR18650B 3400mAh rechargeable Li-Ion Battery for my itaste svd and was just wondering what kind of charger is suggested I have a
Double Bay Charger for Lithium Ion mod batteries
Capacity 2 port
Input voltage 100 - 240V 50-60Hz
Output voltage 4.2V
Max output Current 600mA

Those are what the site I got them says no brand name on the charger but was wondering if there was a better charger seems like it did not charge the battery fully

 

[danca90]

Nitecore i4. I'm kind of in love with mine.

 

[BigBen2k]

xtar VP1; accept no substitute.

 

[suspectK]

Takes like 20 hours to charge with a normal charger. I'm currently looking into a better charger specifically for this battery.

 

[Adrian581]

ahhh so the fact my charger puts on a green light don't mean its fully charged just means its vapable lol do the xtar and nightcore take all size batteries I also have a lil efest battery forgot the right size and don't feel like taking it out to check since its the battery I am using lol

What voltage capacity does your battery reach? My charger has a 3.0 and 3.6 volt rate. The 3.0 rate will get it around 3.8 Volts for capacity, and the 3.6 will get it up to the full 4.2 Volts.

Details:


•Capacity 3400mAh
•Nominal voltage 3.7V
•Charging Voltage 4.20V+-0.03v
•Size: 18650 (Cylindrical

is the details on the battery that the website gives me

Run it 3.6, that is the setting for Li Ion, that charger setup for charging Li Ion and NiCD or NiMH, but you have to manually switch it and CANNOT mix the batterys..the intelligent chargers detect the batteries and adjust charging rates, patters, and voltages accordingly

Remember you can actually push TOO much charge into a battery too fast just like taking it out too fast...most chargers slow charge CV/CC (constant voltage/constant current) for Li Ion, the reason it takes so long charging is Li Ion is capable of pushing tons of current vs recharging

(an analogy) think of it as a big tank (for energy), there is a tiny 1" line going in trickling in (slow charging), when you use it, you open the huge 8" valve at the bottom

The charge rate of a typical consumer Li-ion battery is between 0.5 and 1C in Stage 1, and the charge time is about three hours. Manufacturers recommend charging the 18650 cell at 0.8C or less.

sloooooowly fill that big ole energy tank...then drain it fast

This is the beauty of Li Ion and it's curse...you can't charge it too fast or it increases the change it could go kablooey

With those specs you "could" conceivably push 3400mA into the battery at a 1C rating

the "b" is not a high drain battery and really shouldnt be used with a regulated mod. it has a 6.8 amp limit.
with such a lower amp limit dont be surprised if anything over a 4 volt setting seems a little anemic at times as this battery wil not have the power needed to upconvert to a higher voltage.

personally I only use the B in a mechanical with a .8 ohm coil

I still don't get it lol..... is there a website somewhere that goes into all the different batteries, how they work, and the chargers? I'm ordering my first two mods (still on egos and twists at the moment) in about a week and am STILL confused about batteries.... almost to the point of wanting to order the itaste mvp v2 instead just so I don't have to deal with them.

I've recently spent a good deal of time learning about the different li-ion battery chemistries and researching which specific batteries are recommended for specific applications. I've condensed this information in my blog which might help people understand:

Battery Basics for Mods: IMR or Protected?


I concur with thrasher about the 3400B Panasonic battery. It is not a high drain battery, which regulated mods require for optimal performance. The boost curcuits in the processor need a high drain IMR.

There's more to choosing a battery than the highest mAh rating. The right chemistry needs to be matched to the application used.

When in doubt, always go with an IMR. The one that is the most recommended is the red AW IMR battery.

I got the 3600 mah battery cause I thought it would last forever it last awhile but thought it would be longer what kind of battery should I get for my svd or should I just get a better charger? I am sorry but it all is so confusing

yea me too and I'm an electronics hobbyist.
Read a lot and I think this is the simple version. Someone Correct me if I'm wrong.
-Mechs should have a protected battery
-Regulated pv's like the vamo,svd,eVic ect have their own protection so don't need protected batteries
-Avoid Li-ion. IMR is best
-nitecore i2 or i4 charger
-Panisonic NCR18650PD (high drain-high capacity) 2900mAh 10A Seems to be the only one EVERYONE agrees is a good battery for regulated pv's (li-ion Li-Mn? hybrid)

-AW and panisonic are the best brands
-AW is a panisonic battery
-Efest is the second best brand

You can't trust the mAh specs as well as you would hope...

The most recommended battery supplier for this site is
Genuine AW Batteries at RTD Vapor

I currently rock this in my Vamo V3 for almost 2 days straight of pretty heavy vaping
Batteries : Efest IMR 18650 Flat Top

But as Baditude said...listen to him! He is the forum resident battery guru!!!

IMR is a "grade" of Li Ion...different technologies, different chemical makeup

IMR are better for our uses because they are designed for high drain situation, (some of them VERY VERY high drain), ICR's are protected because they can't handle the load usually thus they put the protection circuit built in

Better explanation here...but Baditude's blog on batteries is more concise

There are recommendations in the link I just provided above. Any of the batteries in the list with 10 amp are suggested.

The batteries that have a higher amp (20 - 30) are specialty batteries for people who are using Sub-Ohm coils on RBA's.

thanks for the help can u suggest a trusted website to buy them?

At one time not too recently in the past, protected li-ion batteries were recommended for mechanical mods. However, the protection circuits in protected batteries fail, and that leaves the volatile chemistry of the NCR/ICR batteries vulnerable to vent flames or worse when they fail. Li-mn IMR batteries are inherently a safer chemistry not requiring protection circuits.

ECF battery guru rolygate recommends using IMR (safe chemistry/high drain) batteries for ALL APPLICATIONS. Hybrid batteries are an acceptable substitue. -- http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html

Regulated mods have built-in protection, but require a high drain battery to operate optimally. Therefore the IMR is recommended again.

Never use a non-protected NCR/ICR battery in a mod. These are sold at FastTech, Ebay, and Amazon, so if you decide to purchase from them be sure you know you are not buying the wrong kind of battery. If not sure, don't buy it.



If using a mechanical mod, a Vape Safe Mod Fuse is recommended as a second layer of protection.

Ah, How did I miss this. I do have a similar list saved from a battery thread. Wish I'd have seen this before now.

I'm pretty happy with my efests. However, I only got them because the shop didn't have flat top AW's. Only button top.
