Best 18650 batteries for power and duration?

[johnm1971]

Just wondering what everyone out there is using and which batteries are the best for vaping? I have a Kanger Dripbox and I am using Samsung INR18650 25R 3.7A batteries in it. I vape fairly heavily and find I am going through about 3 charges a day. Am I using the best batteries or are there some better ones out there that would deliver more power on a full charge and last longer? Any opinions or comments appreciated!

• READ this => Calculating Battery Current Draw for a Regulated Mod

The highest mAh 20A cells.

• LG HG2 3000 mAh 20A CDR
• Samsung 30Q 3000 mAh 20A CDR

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

• RTD Vapor
• Illumination Supply
• Orbtronics
• IMR Batteries
• Liion Wholesale

Thanks a lot! I did buy my Samsungs on Amazon, so that's good to know! I'll check those links out.

Also consider the "new" AW 18650 IMR 3000mAh 20A CDR. Same specs and performance as the LG HG2.

From what I can see from following the links above and searching for the Samsung 30Q 300mAh batteries, they have a maximum continuous discharge of 15A. The Samsung INR18650 25Rs maximum continuous discharge is 20A, which I need. The Dripbox is basically an unregulated mech mod, and the coils that come with it, and that I'm building are around .25 ohms. So, on a fresh charge, my batteries going to be at 4.2V and to fire a .25 ohm coil, it's going to draw 16.8A. I realize the 30Qs LAST longer, but i wouldn't be able to use them, would I?

Looking at the Dripbox it has a max output 60 watts. Not sure how that comes into play.

Here are @Mooch battery bench tests on the three 3000 mAh cells.

• AW 20A 3000mAh Flat-Top 18650 Bench Test Results...a good high-capacity 20A battery, could be an HG2
• LG INR18650-HG2 20A 3000mAh Bench Retest Results...a great 20A battery!
• Samsung 30Q 20A 3000mAh 18650 Bench Retest Results...a great 20A/3000mAh battery!

Mooch's bench tests of the Samsung 30Q revealed this battery actually tested out as a 20 amp continuous, so it tests out better than its official specs.

0.25 ohms is at the limit of a 20 amp battery. I never feel comfortable building that low myself. Everyone is free to set their own parameters, and I can only say what mine are.

I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A batteries, that would be 10A. The Ohm's Law Calculator tells me that a .4 ohm build is as low as I would want to use.

The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, your 20A battery may only be a 10A battery.

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway​

Ok. It says different on the specs on the websites. So it Does have a 20A MCD. Thanks
