largest capacity protected 18650 battery

i know of a 4000mah trustfire light but i know chinese batteries capacities are over stated so i just wanted to know what is the largest capacity liion protected 18650, price not an issue.

thanks guys!

Enerpower + 3400 mah

ok i lied. 35 dollars for one 18650 is an issue. haha. i was thinking 15-20 dollar range. why are they so much???

Keeppower are good from 2800 mah to 3100 mah or sanyo 2600 mah.

Not largest capacity, but good quality/price ratio

Intl-Outdoor Protected Sanyo UR18650FM, 2600mAh, $17.88 / 2pcs (free shipping worldwide)

Because state of the art technology is usually expensive, and these are the best in class. For some applications longer continuous runtime is very important, sometimes even critical. Also, the cells are still rare and stocks are limited, especially for protected cells. Nothing to be surprised about.

In addition to the above, check out: Callies Customs 3100 mah, Redilast 3100 mah, AW 3100 mah

There's lots of suggestions but which ones do you guys prefer?

I've just been recomended a 3100 mAh ampmax 18650, anyone used on? Any good? Apparently a Panasonic cell with protection

As good as AW, RediLast, CK, Keeppower, Intl-Outdoor Store, and other brand 3100mAh batteries.
In fact, most of them are made on same factory, with just different label put on.

I have been using exclusively AW rechargeables without any issues. RCR123, 17670, 18650.

Love the Eagle Tac 3100 mAh 18650. Again, supposedly it is really a Panasonic. Have 5 of them and no problems.

good point. i didnt know those were the only cells out there with that high of a capacity. makes sense. to rich for my blood though

thanks for all the suggestions guys. that battery test chart is extremely helpful havnt picked one yet. im gonna look through all of them to decide. thanks again!

Good find! 23 a cell isn't too bad. Better than 35 a cell for the enerpower 3400 and better than the keepower since you can't buy them unless you buy a 100

Efest 3400mAh's are $7.42/piece + shipping, which kind of makes sense because raw NCR18650B cells cost somewhere in $5-$6 ballpark.

1. mr.lumen is talking about Protected cells. mr.lumen, correct me if I am wrong.

2. If you find 3400mAh for 5-6 bucks let us know

3. You better ask for shipping charges before you hit that buy button

1. Efest 3400mAh is protected

2. http://www.alibaba.com/product-gs/575857900/New_Arrival_NCR18650B_3400mAh_3_7V.html more like 6-7, not 5-6, but still, not much more than $5.96 NCR18650A.

3. I got quoted $9.49 shipping for four 2900mAh ($4.83/piece, so $7.2/piece with shipping) ones, I don't see any reason why 3400mAh ones would cost more in shipping.. so that's just under $2.5/battery.

The group of companies that sell efest cells seem to have some online difficulties at the moment. bestinone, efestbattery, powerwholesale and
bestvaping all seem to be unavailable.

The 3400mAh's were unavailable from these sellers recently, but when they come back in stock (assuming their websites return), expect to pay around $10 -$12 shipping per 4 cells - plus 4% Paypay fees. Still good value.

Very true, the first lot of 3400mAh batteries sold out really quickly, and new stock has been pretty slow appearing. Buying from these guys is also a bit of a pain - it takes a day or so, with shipping and price to be confirmed, but still OK if it comes off. Personally I'll wait a bit - don't really need these cells just yet.

Hmm, that's weird. I never used their sites (I prefer dealing with them directly through Skype), but it's quite weird that all 4 sites went down at once.

Yeah, I know it's the holiday period there, but think they might have screwed up their web domain licensing, or something. I doubt they are really gone, gone. Never thought to use Skype.
