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? I bought these for my own Personal Vaporizer / vape Mod. So far, good cells that run cool and have excellent run time.

Good first impression so far.

First time ordering from a Battery wholeseller. So far so good for Li-Ion. Cells seem genuine, were wrapped properly, came in theor own individual boxes with nice packaging. Shipping, ordering and delivery time all very good. I recommend before purchasing any 'round' Li cell to check out Battery Mooch. His tests are more related to Vaping, but the info is useful in any application. I bought four cells.

  • What device/application do you use this with? Tesla box mod

EXCELLENT BATTERIES

The samsung 20s is a 2000 MAH battery, and it hits VERY HARD, perfect for mech mods, and for LOW BUILDS, it hits HARDER than hd2c, hb2 hb4 and hb6, you cannot get maximum capacity AND maximum MAH both at the same time from a 18650 battery, to those speaking negatively about the 20s, do more research, check out MOOCH , if capacity is what you need get sony vtc5a, sony vtc6, hg2, if POWER or CURRENT is what you need because of low builds, or batteries that can handle low ohms, without getting hot and can SAFELY handle HIGH current draws, then samsung 20s is THE PERFECT BATTERY. Liionwholesale is my ONLY go to for batteries, genuine batteries, and fast shipping, love them.

  • What device/application do you use this with? Eleaf Pico Mega

Great battery life for using low wattage on VW mods

I use this on my pico mega and the first charge lasted me almost 2 days chain vaping at 11 watts with a 1 ohm coil. As far as high power usage, I'm not sure. Thanks for a great product!

  • What device/application do you use this with? Mechanical mod

Best 18650 for mech mods

If you're using an 18650 mech mod and are pulling 30A or more from your batteries then this is the clear winner. It also helps that these are the hardest hitting 18650's available. If you dont need that kind of power there are better options
