Samsung INR18650-20S 18650 - Amazingly high power 18650 battery cell

The Samsung 20S is currently the hardest hitting 18650 battery available. With its 30A 2000mAh rating, it easily outperforms the LG HB series.  Even lower internal resistance (IR) than the the Molicel P26A and Murata VTC5A, although the P26A and VTC5A are 2600mAh cells and this one is 2000mAh. You can view Mooch's testing here.

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

Don't last

Don't use if you vape over 30 watts lol. I vape at 60 and these aren't worth the distance I can spit. I have a feeling they're rewrapped. No go. Don't buy.

Bar none, the best place for batteries.

I have made at least 6 purchases from LIW and they are always great. Authentic quality cells with quick shipping and a free case. I use 20s mostly in my mechs and have a single for my ohm reader. I've also bought 20700's and 21700's here as well. Always top notch products and service.
