Batteries 15400 3.7 V

[bleev]

My nitecore charger will charge my 15400 3.7 v to 4.1 V. I much prefer the higher voltage. When a battery tested on my meter gets below 4.0 I am disappointed in the flavor and smoke.

I think I need a higher voltage bottom feeder with maybe an 18460 battery. Currently using the vapage V-mod 2.0. Thinking the VV reo mod is the proper device for me.

Does the battery maintain voltage for a long time? Currently I need a battery change 2 times a day.

Also does it hurt 15400 batteries to charge them when the get lower than say 3.8 v?

I'm pretty sure than none of the batteries you mentioned even exist... If they do, they certainly aren't standard.
There is a 14500 (same size as a AA battery) and there are 18490, 18500 & 18650)... But that's beside the point.

Unless you are using a mod with a boost circuit, all batteries will start to deliver a weaker and weaker vape as the battery drains. A larger battery with a higher mah rating will last longer and discharge slower than a smaller battery but you will still feel it diminish.

I'm not a fan of box mods in terms of their form factor so I don't know the specific features of any of any given model but you should look for VV and/or VW model with a buck-boost converter that will allow it to maintain the desired voltage output, from the time you take the battery off the charger, to to time it needs to be recharged.

The batteries are 14500. For maybe 4 hours they maintain good smoke but it seems like I'm always having to change them out. Do to larger VV mods larger batteries maintain say 4v for a long time?

Also what is a buck-boost? Got link?

Voltage regulation can be accomplished without buck boost circuitry. The E-Power 14650 regulates voltage without it. 3.7 V is maintained while the battery is charged between 3.7 and 4.2V. No regulation is provided when battery voltage is below 3.7V.

Boost-type power supplies are a better solution because they can boost voltage higher than the battery voltage. There are also different approaches to voltage regulation with the best circuits providing a fixed voltage under load. These are common on better VV and VW APVs.

Sorry for the slow reply...

A buck/boost converter is a voltage converter that is able to deliver (output) voltages that are higher (boost), equal to, or lower (buck) than the supply voltage (battery).
Buck–boost converter

Without getting into the differences in how the various devices accomplish this, all VV & VW devises are designed for this purpose. They allow you to select a voltage (or wattage), within specified limits, and it will attempt to deliver that throughout the entire usable voltage of the battery.

Notice that I said "attempt"... Some devices are better than others. You'll need to do some additional research and checkout reviews of of the devices you are interested in.

Look for reviews where the person doing the video is attaching the device to oscilloscope (or at the very least a digital multi-meter) to check the actual output of the device against the desired output. There are lots of these out there so the search shouldn't be too tough.

My first Q would be which 14500's are you using? Hell of a difference between a Trustfire and an AW IMR in that little V-mod. You have to remember that a 14500 is a pretty small battery, and with that comes limitations. Sorry, but that's just the way it is.
If you want to stick with a small bottom feeder, the new V2 Mini from Reosmods.com is a winner in my book. The 18490/500 battery is a real performer when compared to a 14500.

I have trustfire 14500's they are 4.2 volts fully charged, you might be getting under charged. I get about a day before vapor suffers enough to change out.

I've been using my Nitecore Intellicharger i4 to charge my Trustfire Flame and AW IC 4500 LI batteries....

Out of frustration today I just purchased the Vapage V-Mod XL which uses 18650 batteries. Then I purchased 2 AW IMR 18650 3.7v 2000mAh High Drain Li Ion Batteries. Hopefully they will lessen the battery change-outs a bit.

This is the high drain 18650's I purchased.

not sure a kick will fit a V2 V-mod i know they fit in the XL V-mod but you might want to look into it, personally i never vape under 4.2v on anything so VV or VW is a necessity for me.

 

[bleev]

The kick won't work in the V2 but I have seen on youtube that you can add one under the juice bottle on the XL. Over 4v would be my sweet-spot I think.

I just hope and assume the 18650's will maintain 3.7V for a very long time...so I've read. I could be happy with that.

 

[jazon1]

yea those 18650's will hold a charge for awhile there the same ones i use for my full sized provari they defiantly last longer then aw 1600mah batterys.
