Dual LiPo packs or dual 18650? What gives longer vaping time?

Phone Guy · Apr 16, 2014

I assumed when building a diy mod that the ability to swap 18650 would be king. Apparently I'm now reading people claim parallel lipo packs deliver more vape time?

I vape a lot, and can easily go thru 3x 2600mah batteries on my dna futura or semovar vaping at 12-15w in a day. Would dual stacked lipo of similar capacity perform better? Like 2z 2000mah/2400mah lipos?

I use a 6000mah 3.7v lipo and I never go below 4v vaping a lot. But, I can't remove it. It also stays on the charger most of the day as well at work. So, I'd go with a lipo from hobbyking.

You can get the same Mah with duel 18650 and swap them out if the 6000Mah runs dry on you during the day. But I haven't used the flat Lipo pack to compare but you will have more space filled up in the mod to get 6000Mah in the Lipo's. I can fit 2 18650's and a DNA board with USB charger in a Hammond 1590G box

lipo's have lower internal resistance and always will have better run time and power delivery @ same mah and probably a better c rating. Know that all lipo's are not the same, you can get some bootlegs that are worse for wear..

I try to use lipo's with erryting

but you cannot beat easily swap ion cells when recharging.. But who has only one mod rolling lol..

USE mini lipo connector. With a magnetic back you can still swap batt easily. I would love it if companies started making mods using RC Lipo's. It is beyond my comprehension that this is not already the norm. Space be damned, it is about the vape!

Lipo's work more efficiently so the same mAh should last longer (by how much no idea might be negligible), but lipos will take up more space. Saying that they will handle much higher amps and overall are a safer battery (since they are designed to be used by users) so it really depends what you want. If your chain vaping at low current then your 18650s will probably give you the longest life at a reasonable size, but if you are cloud chasing your lipos would be the best bet. I really can't understand why lipos aren't the markets favourite especially as they can be charged so quickly

Two 2100Mah 18650 Sony VTC4 batteries in parallel in my SX350 box mod last all day + for me. Vaping a Kayfun, 1.5 ohm coil at 14.5 watts. 4.2 volts at 7:30 am and around 3.5 volts at 10:30 pm. I vape a lot too. Fill the Kayfun 4 or 5 times in the course of a day. Thought the info might be helpful. I am looking at the 6000 Mah, 3.7 volt LiPo for my DNA 40 mod. Recommendations for an enclosure appreciated.

I have only found 1 3.7 volt LiPo at hobby king. I must not be looking in the right place. The one I've found, 6000 Mah is too big for my proposed case. Any hints to slightly smaller ones. I am vaping a dual 18650 build now at 4200mah and it lasts me all day so I am looking for something in the 4500 to 5000 mah range. Thanks for any help.

Hi Matt, go to batteries and acc., select all li-po's, and then at the top of the listing will be a row with 12s,10s, etc., select 1s. That will get you individual cells vice packs.

Did that. Still haven't found what I want. The size of the 6000 mah must be a standard as all the others in the 4 to 6000 mah range are pretty much the same size.

This fine print is a not so subtle reminder to always read the fine print before signing anything.

What are other batteries designed to be used by?

Model helicopters and drones mostly. Also r/c cars.

Hi Matt, what's the dimension of your box mod?

Did you have to use the bap cover?

MattB101 · Oct 26, 2014

It's a Hammond 1590G box with the 10mm Bap flat SX350 cover. 50mm Wide x 41mm Deep x 101mm Tall, when assembled. Exterior dimensions. (2"W X 1.6"D X 3.95"T). I used the Bap front because the two 18650 batteries pretty much fill the inside of the box and I didn't have to do a lot of cutting and drilling. If anyone is interested in purchasing a Bap cover they are available from Shapeways.com. I have to say that they are definitely proud of them!
