So I have done some reading on the chemistry in the batteries we use in our mods, and I am starting to think about service life...

Is it conceivable that the AW IMRs (which are LiMn batteries) have a longer service life than the AW P's (which are LiNiCoO2 batteries) when being used on our PVs? I ask as it seems that the AW IMR's Lithium Magnesium chemistry are better suited for consumer-level "High Drain" applications and are often thought of as good choices for "high pulse current" and "high amperage applications". In regards to the Provari, Lavatube, and the Kick, the AW IMRs are recommended exclusively. On the AW P's, it seems there is a higher chance of the battery's internal protection kicking in when you are hitting higher wattages, which is why Provape does not recommend using anything but the IMRs. Provape has also acknowledged that the LiNiCoO2 cells have been used in the Provari with limited success. At lower voltages and watts, it seems to perform well while offering better battery life than the LiMn cells. However, at higher voltages, these batteries do not work nearly as well.

The power requirements of our mods are pretty substantial if you think about it. You could even argue that they draw more power than these batteries were perhaps originally designed for. Does it seem the AW IMRs are best suited to these relatively heavy power requirements, where as the AW P's will be subjected to more stress? Has anyone ever tested to see if the AW P's suffer an early demise compared to the AW IMRs? On paper, it would seem that the expected service life of the P's would be less than the expected service life estimates based on use in other electronics...

(Please forgive me for neglecting to bring LiFePO4 batteries into the discussion. It seems that lithium iron batteries are falling out of favor in the vaping world and so discussion of them would not be as useful. With that said, t
he LiFePO4 batteries have a higher current peak than the LiCoO2 batteries do and a substantially longer service life than either of the two batteries discussed in the above text.)
