***update*** now $15.96 w/ coupon code SD18650. New accounts can get this for $13.76 by applying 110 points during checkout.


Because they are li-ion batteries, they have to go by ship, so they take 3-5weeks to arrive. Being very quality cells, it's very worth the wait.

$17.59 + free shipping w/ coupon code SDBattery


a few things: these are genuine panasonic cells that were modded after market with discharge/overcharge protection circuits (it kicks in so you don't overly discharge/overcharge your battery) generally, these are considered are some of the best batteries ever made. these are the ones you should probably be using in your flashlights

i been using them for about 6 years, starting with older 2900mah/3100mah versionsSmilie

please be sure to use smart charger with these and not a cheapie one that just pumps the juice Smilie

If you are in the market for a quality li-ion charger, Opus BT-C3100 V2.2 in available for $34 + free shipping [discuss]

NOT FOR VAPING / E-CIGS! Don't end up being that guy on the news blaming his ecig for exploding.

Cells are slightly longer than most protected cells. End to end stacking maybe tight.

as a user how much can you abuse these in terms of charging

can i say charge these protected cells (with this particular board) from a straight 5v USB power and expect the board to charge them with the correct voltage / currant or are these only good for some (not so smart charger) and cutoff the charge @ 4.2?v

do you know the board they are using how low does it go down to before cut off 2.5v?

thanks good post GREAT cells i use these & the BF in unprotected form by far the best cells out there
i get the better BF for less then $3 i just hope it a good board i never used protected cells before

i dont know what the cuttoff voltage it. i assume top is 4.2 as it should but I have seen some cutouts at 2.5v but some 2.7v and 3.0v - either case, ideally you wouldnt discharge that low

Where do these ship from? Are they warehoused in the US or are they coming from China?

Good deal. My last purchase for these was $22/4. It's surprising that these haven't been replaced by other high capacity, low current cells. These were released 4 years ago...

For most uses, good batteries. May not fit all devices due to the protection circuit making the cell longer. High drain devices may perform better with 4.3-4.35V batteries, or a different chemistry. These don't perform as well under a heavy load as lower-capacity batteries that are designed to handle 10A+ discharge rates.

Any experience with the vendor though? Could these have a chance of being fake?

if I thought they were, I would never have posted it. Is there a chance? I am sure, there is a chance, but i would trust the vendor

Damn. So hard to justify the cost water ripping apart laptop packs that have 6-8 for $15. Yeah no protection circuit but I haven't had one blow... Yet.. I just them on flashlights and modded my wireless screw drivers.

No, but the cells that are built for heavier loads are more efficient at, say, 3A, than these NCR cells. The NCR18650B at 3A is closer to 3000mAh, and even less at 5A. The Voltage sags pretty bad on these cells at high currents. Say at 70% charge, a 10W light may not reach 10W due to Voltage sag. When freshly charged, most lights will provide full output.

Not complaining - I have eight of these and another six older NCR18650A. They're excellent for most uses, and still perform pretty well in many lights up to 10W per cell. Just have to know their limitations! Higher Voltage ICR and IMR cells will perform much better throughout their state of charge. My one light (single 18650 compact) pulls almost 6.5A from the cell on max output. Can't get max output with a 4.2V cobalt-based cell due to Voltage sag. Of course the protection circuit on these might prevent that much current in the first place.

Still a great price. Under $5 for a quality cell.
