Vapcell K25:  An inexpensive alternative to the Samsung 25R

These are a great cell that performs similarly to the very popular Samsung 25R, but this one is approved for vaping purposes.  It's also cheaper than the 25R.  Not to mention, it comes with a great zip up case if you buy in multiples of 2.

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

Great all around experience

First of all I want to thank Liionwholesale for the great overall experience. This was my first time ordering from them and I got a lot of these batteries (about 18 of them) so I was quite nervous but they came and even with a hiccup in shipping, they still came fast . I haven't used the batteries themselves but I've heard nothing but good things about Vapecell which is one of the reason I ordered this brand. I didn't even know they came in a nice carrying case either so when I opened my package I was pleasantly surprised to 9 of these nice little cases in the box. Its going to take me some time to charge all of these for use but I can't wait to try them in my vape mod devices. I plan on charging these @1000mah to help preserve the life of them a bit more. I bought them to replace my old 18650s that I've been using for a couple years and I'm quite happy Thanks Liionwholesale
