Choosing a battery

[legend_jamesb]

hello there people! Just a quick poll about what battery is better to use.
a. MXJO Yellow/Silver 2600mAh 35A
b. AWT Red 3000 mAh 40A

Every input and explantion would help. Thanks!

I'm definitely not a battery expert. Light years away from it. From what I understand though, if those are 18650s, then they are both misrepresented probably. I read a blog of mooch's that said no 18650 actually has a CDR higher than 25 I believe? Might of been 30, I'm not positive. He has a chart of batteries that he recommends, id go with one of those. I'd definitely be wary of a battery that is represented as a 40 amp, personally. I'm sure someone will post mooch's chart soon though, wish I had it on hand.

I've heard Grimm talk about the mxjo's though. He says they are good, whatever that's worth to you.

I apologize if I'm talking out of my rear end here. I really shouldn't be posting in a battery thread, other than to ask questions myself. I'll sneak away now.

If you need a 30 amp CDR battery neither one of these cells will work. Both are rewraps with exagerated amp ratings.

Which mod are you going to be using a battery in?

@Mooch bench test results:

• MXJO Yellow 35A 2500mAh 18650 Bench Test Results...only a 20A battery, but a decent one
• AWT 40A 3000mAh 18650 Bench Retest Results...only a 20A battery, damaged at over 30A

There are only a few battery manufacturers in the world who make their own "cells", including LG, Samsung, Sony, Panasonic & Sanyo.

All the other brands on the market buy the second and third tier cells from those manufacturers and re-wrap them under their own brand. These are "second and/or third tier cells" which did not meet the higher standards of the original manufacturer. In order to compete with the original manufacturers' batteries (first tier), these other companies feel obligated to publish specifications which are inflated to make them appear superior to those of the original manufacturer.

* (AW is Andrew Wan, a former Panasonic employee who branched out to create his own "brand" of batteries. He allegedly has agreements with the major cell manufacturers to purchase first tier batteries from them. Not all batteries are created equal, so AW tests these batteries for quality. The best get chosen to be AW brand, and are re-wrapped as AW.)

Do your research before you buy. Decide what battery to buy depending upon the application that you will use them.

As far as I know there arent any 18650 batteries out there that are true >30A (or was it 35A). Get the LG HG2s, 20A with 3000mah if you want longer battery life, VTC4 or 5 if you want something with more oomph

with 18650s stick with LG (HG2, HE2, HE4), Sony (VTC4, VTC 5) or Samsung (25R, 30Q are recommended on the forum) batteries.

I prefer LG b/c Sony's are cloned quite often.

I would stick with batteries from the bigger manufacturers if I am honest-the 25R or HE4 is a pretty firm favourite, and a pretty standard battery for vaping now.

The 25R offers a 20A CDR rating, plus, the added safety of 100A for <1 sec, 45A for 5 seconds, and 30A for 6 seconds according to its information sheet.
This is a pulse rating, you should never build to it, I see it as more of a safety net in case of bad situations, just in case.

Also, on the Info sheet there was many stress tests done to the batteries, and all resulted in level 1 failure. These tests included dead shorts for 20 Seconds, crush tests, and even being put in a 120C oven for 20 minutes.

Level 1 failure is leak-level 5 is explosion. Out of the many, many batteries tested, only a few even had level 1 failures.

If you wan't a bit more capacity, the LG HG2 as suggested is good. If you are not planning on higher power vaping, I also find samsung 30Q's to be very good batteries-I find them better than the HG2-remember the manufacturers spec of CDR is 15A though, not 20A, although test results have shown it to work very well as a 20A CDR battery-although I generally am pulling under 15A anyway, so they may be good for you too, but I really, really suggest a 20A CDR rated battery by the manufacturer.

The 25R is solid-but so are all the other batteries mentioned. If you do go down the route of Sony batteries, such as the VTC4/5, please be very careful to avoid counterfeits.
Buy from somewhere you know you can trust.

I hope this helps, and all the best, Conan.

I only buy Sony, Samsung, LG or AW batteries whenever I can help it. The rest are rewraps and usually have exaggerated specs.

Before I bought 26650s for my Stout, I went by Mooch's tests of those.

And I have some Efest 14650s, but found some tests of those online to verify safe resistance for them since they were for a mech.

Both batteries are pretty comparable if that's your only two options. Both have been bench tested to be only 20 amps continuous discharge rate, not anywhere near their advertised rating. Personally, I wouldn't buy either one.

Order some LG, Samsung, or Sony batteries online from either RTD Vapor, Illumn, IMR Batteries, or Orbtronics. These three companies make the vast majority of the world's 18650 batteries, are the technological and innovative leaders in the battery industry, and don't over-rate their battery specifications like the minor companies do.

The off brand companies are merely buying the second/third rate batteries (rejects) from LG/Samsung/Sony and re-wrapping them with their own branding and then over-rating the spec sheet in order to compete with the Big Three. It takes a multi-million dollar investment to build a battery manufacturing plant, and most of these Chinese Efest, Imren, MXJO, AWT, etc companies don't have that investment power.

I only use two different brands and kinds of batteries. Sony VTC4`s, and Samsung 25R`s. The diligent shopper can find the Sony`s for 6 bucks each, and the 25r`s for 5 bucks each, from reputable sellers. There`s no need to spend more or buy batteries that don`t have a long track record.

BOL.

 

[Sil3nt]

Neither, either or LG HG2, Samsung 25r.
