lithium polymer in vape mod?

[nighlykeira]

Hello, is lithium polymer battery safe for mods?

What is the advantage and disadvantages?

 

[fourtytwo]

Sure.
A lot of people use Lipo for mods. Most use them in box mods.

 

[nighlykeira]

is it better than 18650 batts?

 

[fourtytwo]

Depends on you preferred form factor.
18650 batts are easy to swap and charge. Relatively common, inexpensive and durable.
Common flat LiPo's that are used in RC come in a vast number of shapes and are typically used in box mods and charged in place.
I do not know of any commercially made device that uses flat LiPo's where the user removes the battery to charge it.

Cordless phones
RC cars
High end RC remotes
cordless drills and other various tools

there are many applications for this

You are correct sir!
What I should have said was, commercially made VAPING device...

LiPo's are not new to vaping devices.
The Darwin used, what I believe, was a common 3 cell Lipo of the type commonly used in 400 class electric heli's. There have also been a number of small devices from China that used single cell flat LiPo's. All of these, as far as I can recall, used charging ports.

the problem is, Lipos are more violent when not handled properly... so i think they stick to Ion cells, just to help with user error....

its for the best.... you should have seen the mess a Li-Po cell did to my RC boat....

 

[fourtytwo]

I agree.
The lack of a hard shell of common flat LiPo's saves weight and, in many cases, space. This is excellent for RC vehicles but not so much in vaping equipment.
With an RC vehicle, you want light weight and high, fast discharge rate.
Vaping gear requires durability and high capacity.
I think, unless you have a particular form factor in mind where only a flat pack would fit, i would stick with the more common round cell.

The below is from another post, but I thought it was applicable.

IMHO the metal cased round cells are actually more dangerous in a worse case situation.

ive never seen a lipo used in a cell phone i have seen people say they are lipo's because they are flat and look like lipos so they assume they are but all of mine have always been li-ion's even my S3 sitting here with me i just popped open to look and its a li-ion as well.
i thought they blocked the use of lipo's in most mobile devices a few years back after a few in laptops melt down when people were using them.
ether way her mods look fantastic i love how tiny this one looks

The recalls were actually li-ion...here is some info Lithium-ion Safety Concerns – Battery University

Here is some great info from a great source Battery University.

The polymer hype of the early 2000s is still going strong, however, most users cannot distinguish between a regular Li-ion and one with polymer architecture. Lithium-polymer differs from other battery systems in the type of electrolyte used. The original polymer design dating back to the 1970s uses a solid (dry) polymer electrolyte that resembles a plastic-like film. This insulator allows the exchange of ions (electrically charged atoms) and replaces the traditional porous separator that is soaked with electrolyte. A solid polymer has a poor conductivity at room temperature and the battery must be heated to 50–60°C (122–140°F) to enable current flow.The much anticipated “true plastic battery” promised in the early 2000s did not materialize; the conductivity could not be attained at ambient temperature.

To make the modern Li-polymer battery conductive at room temperature, gelled electrolyte is added. All Li-ion polymer cells today incorporate a micro porous separator with moisture. The correct term is “Lithium-ion polymer” (Li-ion polymer or Li-polymer for short). Li-polymer can be built on many systems, such as Li-cobalt, NMC, Li-phosphate and Li-manganese. For this reason, Li-polymer is not considered a unique battery chemistry. Most Li-polymer packs for the consumer market are based on Li-cobalt.

With gelled electrolyte added, what then is the difference between a normal Li‑ion and Li‑ion polymer? As far as the user is concerned, the lithium polymer is essentially the same as the lithium-ion battery. Both use identical cathode and anode material and contain a similar amount of electrolyte. Although the characteristics and performance of the two systems are alike, the Li‑polymer is unique in that a micro porous electrolyte replaces the traditional porous separator. The gelled electrolyte becomes the catalyst that enhances the electrical conductivity. Li-polymer offers slightly higher specific energy and can be made thinner than conventional Li-ion, but the manufacturing cost increases by 10–30 percent. Despite the cost disadvantage, the market share of Li-polymer is growing.

Li-polymer cells also come in a flexible foil-type case (polymer laminate or pouch cell) that resembles a food package. While a standard Li-ion needs a rigid case to press the electrodes together, Li-polymer uses laminated sheets that do not need compression. A foil-type enclosure reduces the weight by more than 20 percent over the classic hard shell. Furthermore, thin film technology liberates the format design and the battery can be made into any shape, fitting neatly into stylish cell phones and laptops to make them smaller, thinner and lighter. Li-polymer can be made very slim to resemble a credit card. Read about the Pouch Cell.

Charge and discharge characteristics of Li-polymer are identical to other Li-ion systems and do not require a special charger. Safety issues are also similar in that protection circuits are needed. Gas buildup during charge can cause some Li-polymer in a foil package to swell, and equipment manufacturers must make allowances for expansion. Li-polymer in a foil package may be less durable than Li-ion in the cylindrical package. Li-polymer is not limited to a foil package and can also be made into a cylindrical design.

hum, I guess the key with most e-cig batteries is being safe with them.... been using Lipo's almost three years and not a single issue....the Darwin's 2-parallel batteries worked great for a year and were replaced with fresh ones and still working great....all the 20d mods I have use flat Lipo's also without issue.....

Most high power batts for e-cigs can cause issues if not maintained and used properly....cockpit trouble (user error) can be reduced with non-removable batteries IMO...just charge in place.....

 

[transamspirit]

If I wanted to use a li-po battery to build a mod, what amperage would be required for a fixed 3.7v setup? A vv setup?

the groove comes to mind when i read this.....

i agree with you, but manufacturers can mess up too...

No amperage (rating) would be required, it depends on the intended use of the mod. You can buy large LIPOs with C ratings of 100 or more.

 

[txredxj]

you would have to figure out what your max amp draw will be to find the C rating you will need (max voltage and lowest ohms used in box mod). C rating is multiplied by rated mah of lipo. so if you have a lipo with 1200mah (1.2amps) and a 10c rating you get max continuous rating of 12 amps. there are lipo batteries with low C ratings that are used in phones and hand held gps type devices that wouldnt work in a mod box.
