2X Panasonic NCR18650 Rechargeable Batteries 2900mAh Li-On and Dual Charger

Batteries looks genuine, but charger is no-name…

Fasttech has the Nitecore I2 charger for $17.90 and the same Ncr18650:s for $11.66, good to deal with and fast shipping too… With the 5% blf discount It’ll be around $28, shipping is free…

You kidding?

5 posts before I even got my post typed… Guess I’m just pretty slow… :slight_smile:

I would go for the Sanyo 2600. In tests they came out on top as the Panasonic’s need to be discharged down to 2.5v to get full capacity. Also the Sanyos held a higher voltage. The Sanyos are cheaper as well.

What tests are you referring to?

Everything I have read shows the 18650B’s to have great capacity and current, specially the unprotected.

Hi man…$10 for 2 cells…wow…Are they protected? Over voltage? under voltage etc…Thanks for the really fast replies. got some browsing and reading to do.

Can you post links please? Is this website a trusted (aka not DD style) seller?

Here if you read this you will see that they only give full capacity if charged to 4.35v and discharged to 2.5v. The problem with this is most chargers cut off at 4.21v and most torches will cut off at 3v. So you can’t get the full capacity of 3400mah.

I will try to find the charts comparing all of the cells. It shows the Sanyo keeping a higher voltage during discharge.

Here have a look at this. You can choose your own and compare.

Erm I really need advice guys…Im totally newb to the 18650 stuffs.
What does unprotected means? It can poof or someting?
Just give me a nice protected, not overly priced battery and a charger for my totally non flashaholic bro whom I will give an E35.

Protected batteries (i.e. a battery with a protection circuit board added at the negative end and the entire cell re-wrapped) have protection against over-charging, over-discharging, and short circuiting. The protection is only as good as the protection circuit.

Those are good batteries. I would choose either the 3100mAh version of the Panasonics or possible these protected Sanyo 2600mAhs for lower cost (with minimal loss of capacity).

EDIT - you keep updating your post as I post! ( :) ) I'm not sure what the difference is between the 2800mAh Sanyos vs. the 2600mAh's - anyone?

Good cheap charger? Hmm . . . from FastTech I would choose one of the Miller ML-10X versions (though you'd need power adapters/USB cables). The ML-102 adds the ability to recharge other devices by USB with a battery placed in it. Or you could choose one of the Nitecore chargers.

-Garry

That’s great Gary!! All I needed. All I need is a decent smart charger for handling the 2 cells! Any idea? Nitecore i4? i2? Anything good and cheaper?

Posted as I was typing. Having to look carefully at it :slight_smile: The nitecore i2 seems a better deal. I would not want to use USB to charge those things. I want them as far away as I can from a laptop/PC!

Oh, the 2800mAh cells need to be charged up to 4.30v for full capacity (FastTech website description is wrong). I'd stick with the 2600's.

For a good "cheap" charger I'll defer to others as I don't want to recommend something I don't feel confident about. I do think the Nitecore should be very trustworthy though. Those or the Xtar chargers.

-Garry

I don't charge from a USB port (those generally only provide 500mA which slows the charger down). I use these USB wall adapters (love these things!). Then you just need a mini to full size USB cable like these (these are short though). EDIT - here's a longer one, but it's a little pricey.

Hum. Searching a bit more :slight_smile:

What Garry said is pretty much what I would say, the only thing I would add is, the charger in my link above may be cheap but they really are very good. I have 2 of them, 1 terminates at 4.16v and the other at 4.21v. so both are perfect, if I want to be a little gentle on my cells I use the 4.16v charger. They are both smart chargers.

I will say again that I would buy the Sanyo 2600 cells, but for me I go Unprotected as I feel the protection Is a little redundant in most cases. But other may disagree.

@marcl: Can this charger (http://www.fasttech.com/products/0/10000436/1046800-portable-digital-battery-charger-for-18650-recharg) charge cells in single config and not 2 cells at a time??

Thanks for your input guys :slight_smile: Any EU or UK plug on those?

Yes it can.

As for the plug you would have to tell them you on in the EU they will send you an adapter, don’t worry about that. The pins are US style but they fold out of the charger and back in when you’ve finished.

Just get it bought you will not regret it. It’s a great cheap charger to start with.

Thnks guys. I just ordered my stuffs today. Was kinda busy lately. Great helping community here :smiley:
