This listing allows you to get our best price at $4.90 per cell and a FLAT total shipping of $2.95 (for USA). Example: 2 cells is $9.80 + $2.95 = $12.75. Ten cells is $49.00 + $2.95 = $51.95, etc.

If you buy 10 or more we automatically upgrade to Priority Mail shipping at no extra charge.


The NCR18650B 3400 mAh is the highest capacity 18650 cell at the best price. So good, the factory price went up almost a dollar in the last six months, and likely to go up again soon, so stock up.


CHOOSING THE BEST 18650 CELL FOR YOU

BY INTENDED PURPOSE:

battery bank, e-bike, flashlight, low watt vape - Super long charge at best price per Wh - Panasonic NCR18650B (green)

power tools, high output battery, drone/robot, vape to 80-100W - Best in class 3.5Ah and 10A  - SANYO NCR18650GA (red)

super high discharge to 140 W per cell - Best in class price & reliability - LG HE4 (yellow)


PROTECTED vs. UNPROTECTED

Protected 18650's have a chip soldered to them and re-wrapped in more plastic. They cut off power when cell gets low to prevent damage to it if it is used in equipment that doesn't protect the cells by itself, for example many flashlights. These chips (PCB's) limit the amount of power the cell can deliver because they have little circuits inside. For demanding applications we don't use protected cells, they are more likely to fail and can't deliver high power when needed.

For battery pack assembly, you spot weld unprotected cells together and wire to a single BMS.


ATTENTION IF USED FOR VAPE/MOD: we understand your desire to have the highest capacity cell for vaping. However, high capacity cells have a different design than "high discharge" cells such as HE2, HE4, 25R, 30Q, etc. If your vape uses ONE (1) cell, maximum allowable use is 20 Watts. In 2-cell mods, 40 Watts is maximum. If you use at higher currents, the cells will fail prematurely. If your single cell vape is used at around 40 Watts or dual at 80 Watts (a common 'light' use), and you want the high capacity cell like this, please get the NCR18650GA, 3500 mAh (red) instead (click). It is more expensive but it can handle approximately twice the discharge current without damage or overheating. 


We stock this cell in unprotected flat top format, and it is our go-to cell for high capacity demanding applications. Unprotected means no PCB chip attached as is common in flash lights. It is a little shorter than protected cells, and while you can make them work in a device that uses protected cells (for example an 18650 magnet spacer), it does not automatically turn off once fully depleted, so you risk killing the cell by over-charging or over-discharging (more likely) if you allow the voltage to drop below 2.6 volts.


Maybe by now you realized that the 7000-9000 mAh cells for a dollar a piece on eBay are as fake as you get with true capacities less than 1000 mAh. Unless you need an extremely high discharge, 20-30A cell, what you want from a cell is a high capacity - long lasting charge. That is what this cell delivers.


We are so sick of people touting their "genuine! 100%! made in Japan!" garbage. All NCR18650's from all those people are the same, made under Panasonic contract with Sanyo Electric Co., Ltd. They all sport the colon spacing typo on the label for those with attention to detail.


Places like Amazon require merchants to pay security deposits to list so the prices are higher, and many sellers manage to over-charge for these cells. Don't over-pay to get the same cell.


We use this model in the 36v 10s2p Full Battery brand scooter battery packs and they are superb. True capacity varies upon discharge rate, but it never disappoints. You could easily pay double for some other cell and get less capacity.


Customers notice they take longer to charge before their chargers click off; that is a pleasant surprise because of the high capacity.


Buy as few or many for the same great price.


USA shipping is $2.95 total for the package for any quantity of cells ordered, so when you buy more than one, you save.


If you buy 10 or more, we'll upgrade to priority mail shipping at no charge, so you'll get it a day quicker.


The Panasonic NCR18650B is the larger capacity cousin to the NCR18650PF. It is also capable of sustained discharge rates of 10A. It is currently one of the best priced performance cells on the market and is used by quality OEM's in a variety of applications such as power tools and high intensity flashlights.


We stock this cell in unprotected flat top format, and it is our go-to cell for high capacity demanding applications.
