Panasonic 18650 2900 mah

Holds best 18650 in the world title ???

Surpassed only by the Panasonic 3100. And it is available with varying protection circuits since Panasonic doesn't add protection at the factory.

seems theres not much of a diffrence...the 2900 is tried and tested

Why are they like $20.00 each ..... Is it for the Gold Lithium Instead of Copper ?

I thought This Was Budget Light Forum ? I'm a broke member ..... hehe ....

I'm Still Waiting On My SkyRay King ....... I wouldn't mind sticking (4) of these Panasonic 3100 in the King !!!!

i ordered 4 of these yesterday .$7.59 each after reading pulsars claim that his king ran 2.5 hours on high on these! hope he wasnt joking

and im also waiting for my king ,,,,,14 days now...

No joke, it ran that long, but of course it will run dimmer as the voltage drops. In the end it's quite low but still very much usable.

Focalprice raised their prices on these, it used to be $6.59 (I think) each for 3-4 and $6.30 each for 5+, now it $6.88 for 3-4 and $6.69 for 5+.

Still if you need 4, that $6.88 shipped is still hard to beat.

Great Tip ..... Thank You .....

Are these a whole lot better than TrustFire Flames? If so then I need to get some of these.

Thanks these look real also with a good price ..... Black Bar Code, 0Z serial # and The Green 3100 maH are $9.52 ea or 5+ units $8.25 ea ...... Thanks

its like comparing a mercedes to a corrola

But without the protection circuit right?

Yes these Panasonic cells have been tested over and over !!!! A large # of BLF members don't use anything else .....

The problem with Trustfire is they tell you 4000maH and some are 2000maH .... and some BLF members have unwrapped their Trustfire batts bought the same day from the same seller and on the body every battery has a different serial # on the body meaning they are recycled batteries ! Sometimes is better to pay a bit more to get better results !

REAL TF flames are very good for the price. Protection circuit is still very important when running batteries in series, e.g DRY, where reverse charging is a real danger.

Trustfire, however, has too many fakes running around. I find it hard to give recommendation for it just because of this, as anyone can run around and buy the cheapest TF they find on eBay, just to find out it sucks big time. Even worse if the circuit doesn't work.

For budget use, I would go for both of these, Panasonic for best capacity/price, and Manafont 2400TF flame for its protective circuit.

But are there any that are protected?

Actually, for some uses, 3000mAh 4.35V cells from LG/Sanyo/Samsung are better than 3100mAh Panasonic’s.

Can anyone show any proof of a unprotected Panasonic cell having a catastrophic failure? If protection is there to just protect against a crappy cell in the first place, why do you need it on a quality cell? Reverse charging only happens when you have a large mismatch, with careful use this can easily be avoided and would actually be hard to achieve using a pair of panasonics and common sense. One of these cells will also have a good chance of not exploding on you even on a dead short.

Use budget lights, not budget cells.

Just because there is no proof doesnt mean it cant happen. PCB can also be good if you dont want to deplete the cell too much.. yeah those Pannys are considered very safe, probably the safest, thats why most laptop cells and electric car battery packs use them. But I still understand people that prefer having a PCB. :)

Reverse charge can happen easier thank you think. Which is why I dislike serial light. I give an example, e.g DRY, 3 batteries. How many chargers with 3 bay? Very few. So quite likely the user will charge two at a time.

And all it needs it just that one time when the user forgot that one battery hasn't been charged. Two fully charged + 1 depleted battery = reverse charge. Easy.

Panasonic is designed to withstand dead short. But nothing is stated about reverse charge, where the polarity is totally reversed. I guess we won't know what really happens with reverse panasonics until somebody try it out :) but I'm not going to recommend unprotected batteries in series until it is proven safe.
