Overkill: High Amp IMR's on Regulated Mods???

[sfmc-x1]

Using the search function I'm having a time trying to lock down a answer to this question.

My collection of batteries are all IMR high drain 18650's, 500's, & 350's. Using with a mix of mechanicals' and a pair of regulated mods.

18650:
Sony VTC5's
MNKE 1500's
efest 2500's purple*
efest 1600's red
18500:
efest 1000's purple
18350:
efest 700's purple

Those regulated mods, a Vamo V2 and a SVD. Both have a 5amp max output.

Is it overkill using high amp batteries on these devices?

Do these batteries have any negative effect on these devices?

Does the high pulse/continuous Amperage ratings even mean anything to these regulated devices?

I still like these devices as they still serve a purpose to my clearo builds.


Cheers.

No problem using high amp batteries in 5 amp regulated mods at all.

Overkill? Not really. service life should be good and you don't have to relegate certain batteries to certain mods.

More for the battery rotation!

Is it overkill using high amp batteries on these devices?

Probably. Once you've met the minumum requirements for amps in a regulated mod (6 - 10), if you have a choice between more amps or more mAh for a regulated mod, I'd go for more mAh for longer battery time.

Do these batteries have any negative effect on these devices?

None.

Does the high pulse/continuous Amperage ratings even mean anything to these regulated devices?

Not really. As stated above, you need a high drain battery with 6 - 10 amps.

I still use cartotanks and a Kayfun on my regulated mods.

A higher mAh rating, even when accurate, isn't everything though. Even at fairly low amp draws high drain batteries such as the LG he2 might be a better choice than e.g. 10 amp Panasonics. As per the measurements of dampfakkus, at a 2 amp draw the LG has 1817 mAh available from 4.2-3.4 v (2053 to 3.3 v) in comparison to the Panasonic's 1844 mAh (2217 at 3.3 v). A difference yes, but not nearly as big as indicated by the mAh ratings. At a 5 amp draw the LG actually delivers more mAh (1731 vs 1565 at 3.3 v).

None.

Absolutely.

A few short months ago I bought a few Panasonic NCR18650PF batteries to use in my SID, eVic and Vamo.

I had a couple of NCR18650B panasonics that came with the eVIc and had been using them in all my regulated mods.

The 18650PFs ran as long as the 18650Bs in my devices and provided a bit more safety as the PFs have a safer chemistry and are high drain batteries.

With an interest in the subject now, I bought more batteries to play with.
AWs
LGs
Samsungs.
Sonys

Surprisingly enough, my AW batteries provide almost as much vape time as my highest mAh rated batteries in my regulated devices in spite of having much less of a mAh rating.

In my opinion, AW understates the mAh ratings of their batteries.

Most other batteries are either right at the stated ratings or in the case of Panasonic, they do live up to the high mAh rating but only if you use them right down to the minimum discharge of 2.5v (which a person will never realize when their mod has a low battery cutoff at 3.2v or so).

My Samsung IMR18650-25R batteries and the LG 18650HE2 batteries (both 2500 mAh batteries) hang right in there with my Sony VTC5 2600 mAh batteries when used in my Hana mods or in my mechs (I sub ohm some with RDA's between .7 and .55 ohms)( all used well under 20A discharge).

Looking at the discharge curves for these batteries explains my experience. The curves show that while the 25R and the HE2 have less capacity than the Panny PFs and the Sonys, they stay at a higher voltage, longer while discharging than the Panny batteries and keep right up there with the Sony in the voltage range I use.

All of the batteries I mention are quality products in my opinion. They seem to provide good service life, don't seem to vary much in batch to batch QC and are reasonably priced. (except the Sony is getting expensive now).

None of the listed batteries provide much more run time than each other. I have found that I can grab whatever is charged and get similar runtime but the 10A pannys have fallen out of favor for me as they are underrated for my Hana and dripper builds and only good for my other regulated, lower wattage mods. They don't fall into my grab and go rotation.
