Pros, easier to get custom shaped batteries to allow for varied physical mod design. Generally regarded as safer then replaceables as there's less likely to be user error in manipulating batteries. Manufacturers can also assure the proper Lipo is in there to meet the load, unlike replaceable battery setups where the manufacturer can only advise you on what batteries to use, but folks throw in whatever they find on sale on eBay.

Cons, First, it usually only recharge in the mod. Second, unless it's built to be changed by the user (easily as an actual feature not prying it apart yourself) when the day arrives that the Lipo will no longer hold a charge (which it will, all these batteries can only be recharged x number of cycles, 18650s or Lipos), you have a brick. Typically in a higher end mod the option to swap Lipos is available, so it's more an issue for the less expensive mods that use internal batteries. Third, the IMR chemistry of an 18650 is actually safer than that of a Lipo, so that failures are less likely to be as dramatic as flames shooting across the room. Not to say Lipos are unsafe per se, given the large numbers in use they clearly are safe the vast majority of the time, but they need to be treated right just like any other battery.

The M-17 is great mod with a good Lipo. It is also fairly easy to replace or upgrade. Axisvapes also now do a model now that uses either 18650s or 26650 batteries.
Another pro that Eskie didn't mention is from a design perspective you can fit more power into a smaller lighter package.

Not much to add that hasn't already been stated. I had one of the original Innokin MVP's which had a Lipo battery. My sister has it as a backup to her iStick 30, even though its now over three years old.

I've always been a fan of regulated mods that use replaceable IMR/INR batteries. A mod with an internal Lipo battery is useless if you are caught out with a drained battery; with a mod with removable IMR/INR batteries you can carry a spare or two with you, quickly change out batteries, and continue vaping.

I also like being able to specifically choose what battery to use in a mod; unlike Eskie, I don't trust Chinese manufacturers to know the best battery to put inside a mod. As an example, Joytech included an ICR chemistry battery (the Samsung 26F) with their original eVic. This was a poor battery choice considering the safer chemistry IMR/INR batteries that were available at the time. Do not use the Samsung 26F battery above 5A or 20W!

Lipo batteries, like ICR batteries, are not "safer chemistry", like IMR/INR batteries are; Lipo's depend upon the protection circuitry of the processor to be safe enough to be used for vaping. That's probably why you don't see many mech/unregulated mods using Lipo batteries. Issues with Lipo's are relatively rare, but when they do occur they are rather spectacular in a bad way. Issues with IMR/INR batteries in regulated mods are even rarer, and when they occur they generally just vent hot gas and don't flame out of control.

I'm not a big fan of USB onboard charging, which internal battery mods use. Just my personal observations from comments on this forum over the years, they tend to have saftey issues more often than external box chargers. Again, I like to choose the charger that I'll use to charge my batteries, and not depend upon a Chinese manufacturer to make that decision for me.

Since some manufacturers are now offering replacable Lipo batteries in their mods, I'm beginning to relax my bias against Lipo batteries a little. For my :2c: I still find IMR/INR chemistry batteries to be preferable.

  • For those who want to learn the differences between IMR, IMR/hybrid, ICR, and LiPo batteries. What do those numbers and letters on batteries mean? What's an amp rating and why is it more important than the mAh rating when choosing a battery for vaping?

My two DNA 200 boxes use Lipo. I like them but it doesn't have the same capacity as let's say a Rx200. In fact I wouldn't recommend Lipo if you want the thing to last you whole eight hour shift because it won't.
So, it's 1100 @ 200w, 3000 @ 8.5w?

LOL no! Lipo mAh are EXACTLY the same as any other battery in the world. Watt-hours is what you need to compare it too. If I take 3 3000 mAh 18650, wired in series, I get 37.8 watt hours. That means the battery can maintain 37.8 (might as well round up to 40) watts for one hour. If I have a 3s 900 mAh lipo I will get 11.34. So no a 900 mAh lipo does not have 3x the capacity that an 18650 does.
