Genuine LG Chem F1L 3350-3400mAh batteries.  Absolutely the biggest mAh capacity you can get in an 18650 at a great price.  We recommend these over the NCR18650B since they are just as good and have better availability and pricing.  They can't handle the current that some of the other batteries can but as long as you're not running lots of current these will last a long time.  They're happiest at 1-2A each although they can handle spikes up to about 6A.

Also as bare cell, or with pre-welded tabs. For the convenience of folks who are building packs, we also this product "with tabs". You can view the LG F1L With Tabs here.

Please note that these batteries are not appropriate for most e-cigarette applications due to low current/watts capability.

Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
  • Charge fully (to 4.2V) before first use
  • Never charge batteries to 4.3V or above
  • Do not charge unattended
  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
  • If you must store your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
  • Use only high quality battery chargers
  • Do not expose to heat
  • Do not connect the positive contact to the negative contact without an appropriate load
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

  • What device/application do you use this with? Vaping mod
Good battery not for vaping

These would have been great however not for my needs. I haven't used yet and there still in the box unopened I'll probably return. The amps are to low for vaping at higher then 40-50 watts

Liion Wholesale Batteries

Hi Anthony - Thank you for your review. You are correct, these are not the batteries you should use for a vaping device due to the low power rating. To choose the best batteries, you can refer to our regulated mod calculator ( which can estimate how many amps you're using, depending on how many batteries are in your mod and how many watts you're using it at. We will contact you via email with our return/exchange information.

32 for 32

Received 32 'clearance' cells so I did a complete charge cycle test on each one. All 32 were within specs, so great deal on an excellent product. They were also all (properly) partially charged when they arrived.

  • What device/application do you use this with? Test batteries for BMS test boards.
Exactly as described

The date code S197 (which is July 2019) matched the sample photo requested. This means that the batteries will still have almost full life remaining. I tested the batteries and they measured 3.31 Ah and 11.25 Wh. Great product and great price.
