Confused about NCR18650PF.. Protected/Unprotected

[8a31]

Ok I just confused the &^% out of myself while trying to find new batteries. I have decided on Orbtronic/Panasonic NCR18650PF. The problem I am having is the battery comes in a protected and unprotected configuration (so it seems). Doing a search I can find them listed as 3.6V and 3.7V. THIS THREAD states they are all 3.7v and the 3.6V is just misprinted.


I was going to order the batteries but then notices some sites list them as protected and others unprotected both showing identical part numbers. Then I looked at Mountain electronics site and they list part numbers of NCR18650PF-PROT for the protected Orbtronics branded and NCR18650PF-BT for unprotected Panisonic brand.
My smok SID says to use unprotected batteries but some of the most in depth threads here say NEVER use unprotected batteries.


This brings me to my 2 questions. 1) does the protection circuitry actually matter with this being a hybrid battery? 2) Which one would be the best for me to buy?

Get the unprotected ones. Your SID has all the protection built in.

Orbitronic adds protection to the Panasonic cells. It is not needed for those hybrid li-ion cells

I agree with anumber1. Get the unprotected version.

The NCR18650PF is an IMR/hybrid battery made by Panasonic, and Orbtronic re-brands them - either with or without protected circuitry added. The protected version is for flashlights; in fact Orbtronics has a disclaimer on their website stating that these are for flashlights and NOT for e-cigarettes.

The un-protected Panasonic/Orbtronic version is an excellent battery for mod use.

Thank you Anumber1 and Baditude for your help. That is what I had hoped but after reading some of the more comprehensive threads about batteries I wasn't sure.
