Battery choices

[cyberwolf]

There is a lot of information on this forum regarding batteries for mods and after reading a lot of it, I am a little overwhelmed.

What would be the preferred battery for a flashlight mod using a 510 atty? So far, based on what others have used, it looks like the 14500 or CR123s would meet my requirements, but I can't seem to find a definitive answer. I am not looking for high voltage, but an earlier 901 box mod that I made with 3 AAA batteries did not seem powerful enough.

Has anyone run across a list of types of batteries that work for mods and possibly suppliers that handle them? Any help would be greatly appreciated.

I like the 14500's because they're AA sized (just slightly longer). I know I can to to Rat Shack and get battery holders for them to use in whatever mod I have ratteling around in my head.

You will never get a definitive answer because the battery size is determined by whatever flashlight or box you use to make a mod will allow.

Battery size is directly related to the time it will work before needing to be recharged.

The smallest being a factory battery (180 mAh), and the biggest
a 18650 (2500 mAh).

The atomizer you choose to use has nothing to do with the battery size, you can use all batteries with any atomizer.

The milli-amp hour is the standard unit of storage capacity for a cell.
It is analogous to "gallons of fuel" for an internal combustion engine. The milli-amp hour rating of a cell tells how many constant milli-amps of current can be supplied by the pack for one hour. This rating can be used to find the duration that a battery pack can provide given a certain draw.

So depending on what you want, you will have to buy a case (flashlight or box) accordingly.

This table has the most common used batteries for modding and their specs.

They have 25500's at DX now overrated at 5500 mah. The real mah is 3500 which is still pretty amazing.

How about 26650 @ 4000 mAh...

LiMnNi Rechargeable 26650 Cell: 3.7V 4000 mAh, 10A rated 14.8Wh

That table is what I was looking for - thanks! I think I am going to just get a couple of CR123s and 14500s and see what evolves.

 

[cybervex]

I should make someting out of that 26650 SOmething I would only have to recharge once a week

 

[cybervex]

Maybe 4 of them. 2 in parallel and 2 in series for a 5v mod rated at 8000mAh

Hehe, that is crazy, but something I might try myself sometime.

I took apart a laptop battery today, 2 of them actually, one of them had 18650's in them, the other are different somehow, seem the same size but the only info on them is this:

D

MBLM4C9
063467

Seems to read 6 volts, but it doesn't provide what appears to be 6V in my PV as I can put 2 CR2's in and the atty heats up a lot more.

Wish I could find more info on them. My best guess is they are D-cell Lithium type rechargable batteries.

EDIT: Identified these batteries, there are markings on them that are extremely hard to read. Sanyo UR18650FM. Odd how they read such high voltage on a multimeter though.

My personal battery of choice now for powering my own e-cigs is four AA 1.2 volt Nimah rechargeable's, they actually charge to 1.42 volts and make an in series voltage of 5.68 volts. Their 2000mah (you can get higher capacity) will very easily provide a full day's vaping no matter how much you vape and what I particularly like about them is they seem to take a lot of charges and discharges without loosing their capacity or loosing their ability to supply the current needed to produce good vapour. They are also very cheap and easy to get.

Very small Li-ion batteries may start out with a very high Mah capacity but I think the way an e-cig drains power from them ruins them and it doesn't take very many charge and discharge cycles before they no longer have anything like the Mah they started out with.

How do you know if the batteries are protected if the manufacture doesn't state it on the battery or you don't have the packaging? I bought 4 CR2s (3v 800mAh) off ebay but I think they were in a bulk container. I recieved them without packaging so i have know idea if they are protected or not. I noticed the positive terminal has two holes. I have no idea who's the manufacturer is either.

As far as I know there is no such thing as a protected CR2. Someone may be along to prove me wrong though.

AW used to sell a protected CR2 (3.6V, though), but doesn't anymore. You can buy the PCB's from DX and make your own from unprotected cells, they come in 14mm, 16mm, and 18mm (16 and 18mm limit current to 10A, 14mm to 3A). These are not the same as the ones you can find at Battery Junction and elsewhere, they have the metal underside that serves as the new negative contact. The hard part is the ultra-thin heatshrink, I can't find a source for something big enough for 18350's that will sell it in less than 500+ foot rolls ($130+), that actually has it in stock. Most people could use ordinary thin wall or even double-wall or adhesive lined, but I can't make it work (standard thin-wall increases an 18mm battery to about 19.5, which is too much for me).

Warning for ultra-thin heatshrink: do *not* use a torch, or a high-temp heat gun, even a low-temp setting may be too much. Try a hair-dryer.
