unprotected vs protected batteries

[mikeyv1984]

I am new to the forum and wanted some input on a question ive had for quite some time:
I buy aw and efest imr 18350s and 18650s for my mech mod and i use the same batteries in my vamo v5. The vamo gets hot when i take a 7 second hit. I was wondering if i should use protected with the vamo. It occurs with all of my atomizers (russian kraken and aerotank mega), running around 2ohms . Output is rms.

Im no expert but I have been told to stay away from efest. I use vtc. I sure some one will be along to correct me if im wrong.

NO - NEVER use protected batteries in a VV/VW mod.

In fact, there is no reason to use protected batteries at all these days.

Efest are ok, others such as are AW,Sony, Samsung, Panasonic and maybe some others I can't recall this early are considered by many to be better.

One's with "fire" in the name are generally to be avoided.

Protected batteries in general should NOT be used in a regulated mod. While they may work, there's an equal chance that their "protection" and the mods circuits will conflict, and not perform well. In a mech they're fine, although the newer "safer chemistry" IMR type batteries are the ones to look for when buying new ones.

Don't scrimp on your batteries, get them from known reliable sources.

The reason for "protected" is because that battery chemistry (Lithium Cobalt) can explode should the battery be made to vent. Lithium Cobalt batteries are also a very low "C" rating, so they don't have the performance that we need for vaping. (only work for low voltage/high resistance devices)

You want to look for Lithium Manganese (LiMn) IMR or LiMn Hybrid batteies which are safer chemistry and have higher C ratings.
There are also a lot of counterfeit batteries on the market, which makes where you buy batteries even more important than which battery you choose.

Neither AW or Efest make batteries. (same goes for Orbtronic) They buy batteries and put their labels on them. So it's important to do your homework, and figure out which battery they use. They use good batteries, you just need to know which one it is. So that you know for sure what it's limits actually are.

For a list of IMR (Li-Mn) and IMR/Hybrid safe-chemistry, high-drain batteries for vaping check out Baditudes blog: Battery Basics for Mods
- choose the safest and right battery for your applications here. Includes a list of name brand, high-drain, safe-chemistry batteries with mAh & amp ratings in 18350, 18490/18500, and 18650 sizes.

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
* Lighthound
* Orbtronics

Hello Mikey and welcome. There is a wealth of information to be found here. Happy vaping.

Protected batteries are never to be used anymore. They are more dangerous.

Protected will not work right in a vamo because they are typically 2-3 amp batteries or less. The vamo can draw up to 6- 8 amps potentially to run the boost circuit. Especially when the battery gets lower on power.

If the vamo is getting hot it is most likely a contact issue in the threads causing a weak ground (-). This creates resistance at the joints and resistance is heat.

Clean all contacts well, and using noalox really does work wonders for improving ground connections.

2 ohms is actually peaking the vamo with a single battery, you will actually barely be able to hit 15w when the battery drains from full.

I use efest, they are fine and safe.

I can highly recommend that you stack a set of new 18350 imrs paired for life. (Read safety information in my stacking blog or other source) The ouput will increase substantially to 30w in voltage mode and the stress on the chipset will be much lower. Battery life will be double what your used to.
