Samsung INR18650-25R R5 2500 mAh (GREEN) vs Built in Battery

[Nevets80]

Hi Everyone,

I have an eleaf iStick 40W TC that I have enjoyed for quite some time with a Kanger Subtank Mini 2. I was on my way to get another one, since the battery life does not last but maybe half a day or so and I need an additional PV (I have others, but not with TC), when I seen the new eleaf iStick 60W TC. I am ready to also try the Kanger TopTank that is available, so I thought about getting the new Kanger tank with this new 60W TC PV, but then questions filled my head, and I was hoping that I could ask you for your help. I think that it would be helpful to note, I am looking for something small like the 40W and 60W (hand-held small devices for on the go), so moving to something bigger with double 1850 capacity is not for me, as well as I am fine using the 40W at only a temp of 270 degrees at the locked 40W with a 1.5 Ni coil from Kanger.

My first question is about using the Samsung INR18650-25R R5 2500 mAh (GREEN) that is recommended by many in the reviews I have read. One of the main reasons I wanted another iStick is due to the fact that the batter life does not last that long, and with switching to one 1850 batter cell, it appears that I get even less batter life than the built in battery the 40W has. Is this true, that moving to a single battery cell such as Samsung 25R Green will actually decrease the amount of battery life I get with a built in battery?

My second question is, has anyone experienced the MELO 2 and Kanger Top Tank, and can provide brief information as to why one is better than the other (tank size, usability, each using different 'brand' of coils, etc.)?

I am fine with my 40W TC and Kanger Subtank Mini 2, but as with anything, there usually is a reason for looking into new and improved PVs and tanks as they are released and I was hoping someone could help me in determining if these new tanks and PV are better than the 'older' items I currently have.

Thank you!

The 18650 battery fits in a replaceable battery mod.
Do you have a replaceable battery mod?

 

[Nevets80]

I don't have one yet, the iStick 60W TC I am looking at does though. So therefore I have to decide if I want to buy this mod and then buy the 25R Green battery cell, beginning the journey of replaceable batteries. Since it has 2500 mAh, and my built in battery on the 40W TC has 2600 mAh, I am not sure the benefits of it other than buying a few replaceable batteries that I can charge outside of the mod.

The main benefit of using a mod which uses replaceable batteries is, when the battery dies in a year or two (about 300 charge cycles), instead of replacing an entire mod ($50 - $100) all you need to replace is a $6 battery. Of course, you need to also purchase a decent box battery charger for about $20.

If your mod with an internal battery runs out of a charge, you're finished vaping until you can recharge the battery. With a mod which uses an external battery, when that battery runs out of a charge, you replace it with a spare that you carry in a plastic battery case. I don't leave the house without my mod and two spare charged batteries in a battery case.

Another thing to consider is, the internal non-replaceable batteries are LiPo batteries, which are not safe chemistry. When they go into thermal runaway, they burst into flames. IMR/INR replaceable batteries are safe chemistry; about all that they do when they go into thermal runaway is vent hot gas.

I'm also not of fan of on-board battery charging of internal battery devices. The USB charging connections tend to wear out over time and can prove to be dangerous.

LG HG2 $5.99 3000mAh High Drain IMR Battery INR18650HG2

These should last longer than the Sammys.

 

[Nevets80]

Thank you so much for the information on the batteries, as I was unaware that built in batteries were LiPo batteries, and I did read about the dangers of those. And thanks for the LG HG2 suggestion, 3,000mAh is much better, and I think I have made my decision on the mod/batteries and the need for an external charger. Any thoughts on the new MELO 2 that comes with the starter kit, versus the new Kanger TopTank that is replacing the sub tanks?

 

[Nevets80]

Sorry, one more question outside of the tanks. When purchasing the LG HG2 batteries, is there a recommendation for the battery charging case that I should purchase along with it?

 

[Baditude]

You're talking about the box battery charger I presume.

Any charger made by Xtar, Nitecore, Pila, or EFest Luc are recommended chargers. All of these can be found online at ecig stores like RTD Vapor. Also good prices on batteries to be had there.

 

[Nevets80]

Thank you, yes box battery charger is what I was asking about, and I see an Xtar VC2 charger that can be a good 'starter' box battery charger for me to begin charging the two LG HG2 batteries I am purchasing. Thanks again!
