Due to some misscomunication I’ve ended up with 50 unprotected Panasonic 2900 mah cells that need homes. I’m willing to sell them at cost, $5.00 plus shipping. I’d prefer to sell them in larger batches instead of 1 or 2.
These are genuine cells and I’ve tested a few and they meet the specs.
If anyone is interested in purchasing some please let me know.
Thanks, Kevin
Hi Kevin,
Would it be possible to post a pic of one of the cells with the wrapper info showing, please? That would help a lot!
Thanks.
Post a pic of all 50
Shipping cost for 4? Thanks.

Here is a iPhone pic of the cells. I ordered these from keeppower by the way, I didn’t specify that I wanted protected and I got these instead.
I think the best way to ship them would be USPS flat rate box, so $5 to ship them.
Where in NC? I may be able to pick them up and save shipping even, lol.
PM sent.
I’m in the Charlotte area. If that’s close to you send me a pm and we can work something out.
Not real close, in the Durham area, so 2.5 to 3 hours. I don’t need them that much, just figured if I could pick some up I would, lol.
I would be interested in 4 or 5 if possible, also sent you a PM.
Thanks
I'll take 6. :) So would that be 35 dollars? Just give me a total and your paypal address. Always willing to help a BLF member. :P
I'll take 8 - I'll PM you.
We're glad to have you onboard, LowLumen!
All pm’s have been replied to. I’ll ship them out next week.
Thanks Kevin, Count me in for 4 and I will send paypal payment today.
And thank you Raccoon City for the warm and thoughtful welcome.
I’ll have to get over to ‘Introduce yourself’ today and say hi to a great group on this forum.
I will take 4 as well. PM me PP info please (thank you Kevin). Welcome LowLumen.

Pretty new to this, so thought I might ask. Does these cells being classified as “unprotected” count as a selling point? I understand what protected cells do, would the only difference in a regulated light be that I’d have to pay attention to cell voltage so as to not over discharge them? Being unprotected, does that mean I can pull more than 3A from the cells?

-To those with lights that will not fit a protected yes (and others see point 3)

-you got it!

-This depends on the protection circuit. Some cheaper ones will trip at around that level.
-There will always be some resistance added to the system by adding the protection circuit, so if you are pushing a cell to its max discharge limits the protected cell may slightly diminish the peak output vs an unprotected.
Personally I have no issue running unprotected in single cell applications, but for a multi-cell high current light? Protected cells please!
I would never run a multi-cell light with unprotected (unless they are run in parallel).
Also, it’s a good idea to use a driver designed for li-ion cells; one that will shut down or drop to a low level, or give some warning when low voltage is detected. Another consideration is the integrity of the light against short circuit. If there is any possibility of a short (bent over spring, etc) the protection circuit will save you where the unprotected cell, capable of tremendous current delivery, I don’t want to think about what might happen here. You need to handle these cells with extra extra care, and never allow the terminals to short. Also, make sure you have a well behaved charger.
Hello kbark,
I would like to take 4-6 of these batteries, so that’ll be $25-35 with shipping right?
Thanks!
