can i have a more mah ?

mAh's are not important. What is important is the max discharge rate. Don't by a battery solely on their mAh ratings. Buy high drain batteries, they have less mAh's but the up side is that they can safely supply the amount of power that is needed to vape.

If you go only for the mAh and disregard it's max discharge rate, you could hurt your battery and it will stop working sooner rather than later.

Some battery makers, I'm looking at you with fire in your name, have been known to overstate how much they hold. Take the claims of 6000 mah with a grain of salt.

The vtr and 134 are both regulated devices. They have electronics in them to control the electricity. All regulated devices have an upper limit to the amount of energy they will ask for, in your case it is well under 10 amps. An unregulated device, mechanical mod, has no electronics and can ask for a lot more from a battery. If you get into mechanical with low ohms you need to know a lot more about batteries and electricity. Also, some of the new regulated devices require more than 10 amps but the vtr and 134 do not.

As p7willm mentioned, the OP is looking for batteries for 2 regulated mods with lower discharge amp requirements.

In general, it's important to find which is important for your mod. For unregulated/mechanical mods high discharge amps are important because they are controlled by the overall resistance of your circuit. With regulated mods, your discharge is capped by your circuitry, in this case I believe it's 5 amps at the atty and likely less than 6 amps at the board. So for regulated mods, if you can meet the discharge requirements of the mod with some safety margin, then capacity (mAh) becomes more important.

I've seen too many reviews on boards where people slam the Sony VTC line of batteries as being overhyped because it didn't perform any better on their vamo/svd/mvp/vtr/provari/et all ad nauseum. If the mod won't use more than 6 amps, you won't notice a difference between the AW and VTC5. Ultimately, there is no point in spending money on Amps you wont use when you can spend it on capacity you will use :)

I would like to clarify some points. Regulated mods which use pulse width modulation need 6 - 10 amps of power available for the buck boost circuitry. This rules out using protected ICR batteries, which typically have less than 3 amps available despite large mah capacities. All things being equal in meeting the amp requirements of the regulated circuit boards, then yes a 30 amp battery would be overkill and higher mahs become more important. -- http://www.e-cigarette-forum.com/forum/provape/334831-technical-why-high-drain-batteries.html

Many batteries claim to have large mah capacities, but much of those added mah are at the low end of what a mod can use as the battery voltage falls. If the mod can't use the extra mah, what good is it? Works for a low drain application like a flashlight, but not in a high drain application like a mod. -- Question for the tech engineers at Provape

"There are cells that claim to have the same or better capacity as the AW cell BUT their internal resistance is inferior. If the cell has a higher internal resistance it will drop more voltage when current is taken out and as a result the ProVari will indicate it is at end of charge when it could have a significant amount of capacity remaining. We vapers are simply borrowing the technology for our own purposes.

What good is this capacity if it cannot be utilized by the ProVari? It is of NO use, so why use it?"


Ultimately, there is no point in spending money on more mahs if your mod can't utilize them. Lets not forget, these batteries were not designed for use in mods, but for low drain applications such as flashlights, cameras, and laptop computers.

It is your choice, take a look around at options. Stay with a good brand like Sony, Panasonic, or AW. You can take a look at data sheets from these manufacturers or 3rd party testers, since they are meant to be OEM products they have corporations with lawyers to answer to, not vapers.

Sony is a very good brand for batteries, but the focus of their VTC line of batteries very high discharge (30 amp) they have a pretty low internal resistance and fairly flat discharge curve. If you are concerned about capacity, the VTC5 is 2600 mAh with a good discharge curve

Panasonic is a very trusted brand for batteries with legitimate stats. The older CGR18650CH (10 amp/2250 mAh) have a better internal resistance and discharge curve than the AW 18650 (10 amp/2000 mAh).

Using 5 Amps, by the time you get to 3.5 volts the batteries have consumed:

Sony VTC5: ~1250 mAh
Panasonic CGR18650CH: 800 mAh
AW 18650: ~700 mAh
EDIT: Found the NC18650PD (10Amp/2900 mAh): ~1125 mAh

This is the capacity you actually use. The Sony VTC5 starts with a higher overall capacity and has a good power curve, so it takes longer to get down to 3.5 volts. I went with the older Panasonic because I couldn't find the data sheets on the current line.

Hope this helps and doesn't just muddy the waters more :)
