I searched the board but I couldn't find the answer.. so here goes...

Let's say I have a 30 amp Sony battery at 2100mah but I'm using a regulated mod that will only go up to 4 amps; will my battery last longer because I am not using it up as quickly??

In other words, I'm using a Russian 91% coiled to 1.5 ohms and when I run it on my eVic Easy Head (gotta love the name of that one) in regulated 3.3 volts, I get over a day of vaping. When I run it in "unregulated" mode, I still get about a day of vaping. The battery used is a Panasonic NCR18650B 3400mah max 6.8A.

I found a good deal on some Sony's 2100mah/30A and just wondering if they will work just as long since i'm not drawing too much amperage from them??

Sorry for my battery/electrical ignorance...

I can't say for certain about the suggested battery for the Evic, but most regulated mods work most optimally with a "high drain" battery for the boost circuit in the processor. These are typically your IMR and hybrid chemistry batteries (ie the Sony us18650vct3 (hybrid) 1600mAh 30A).

The Panasonic NCR18650B 3400 mAh battery is not a "high drain" battery and not the "best" choice for most regulated mods. Much of this battery's extended capacity is not in the useful range for a mod, and its best application is for other devices such as flashlights.

Thanks for the info Baditude! I am definitely going to pick up the Sony's because I'm getting a couple of TRUE mechs in soon. No circuitry, etc. so I was curious as to whether or not I would get the same life out of them as I do with the Panasonic's in my VV/VW mods.

Thanks again. Will read up on that.

I would skip sony and go for hybrid imr high drain battery. 1500-1600mah is really low capacity.

I'm curious to know whether the Sony batteries might last as long as the higher mAh IMR & hybrids will because of their greater amperage reserve. If using lower (normal and not sub-ohm) resistance loads, they won't be stressed at all and just might last as long as the higher capacity batteries.

I have no experience with this combination so I don't really know. Someone like Thrasher might.

ya got me on that one, lol.

I would think your going to get better life overall from not driving the battery too hard but I dont see how you could go much beyond the actual capacity of the battery

in something like the situation your describing with the evic your actually running under the output of the battery and at 3.3v i would assume your seeing the full capacity of the batteries rating as your pulling a pretty light 2 amp load.

you might be able to pull maximum life from the sony but I dont think it will ever last as long as the 3400
as it is approximately 60 ish% of the 3400's total capacity for the sony


in unregulated mode it actually runs wide open?

I'm going to check it when I get a chance in unregulated mode. According to Joyetech, they "say" it runs at full battery level, but I don't recall seeing what the safety cutoff amp draw is on it.

I wondered about the 2100 vs 1600 mAh thing. Seems Sony has a new battery out, US18650VTC4 at 2100 mAh and still 30A. Nice :2cool:

Yep, I was talking about the "new" Sony that is 2100. I would believe, since it's Sony, that the mah would be what they say it is not like those xxxxxFIRE batteries.. which say they're 4000+mah and they last maybe 30 minutes!

The mAh numbers are taken from lower power discharge testing so we'll never see the whole capacity because of the way we use them. But all manufacturers do that so you can compare AW, Sony, Panasonic, MNKE, etc, to each other accurately. The numbers for the xxxfire batts are just plain made up numbers that look good to unwary consumers to get them to buy.

Whipped out the dmm today and the reading was 4.1 in either mode! So, my guess is that because there was no atty on it to create a load, i would just get pure battery voltage????? I believe it needs an atty on it to work correctly... my vape is definitely different when i switch modes. I could be imagining it vapes differently as well since the led changes color and psyches me out. :)

I tested both of my eVic Easy Heads and they both gave the same reading.
