Genuine Samsung 30Q 3000 mAh batteries.  This is an amazing cell, extremely low internal resistance similar to the 25R but with a higher capacity of 3 Ah.  A great battery for 10-50W per battery devices.  As always, we've done extensive testing to be sure they're real so you can be confident you've got the real thing, grade A.  

Note that these can either be made in Samsung's South Korea or Malaysia plants.  These batteries are equivalent with the same part number and you may receive either one since they are commingled.  The Malaysian ones are listed as Samsung SDIEM whereas the Korean ones say Samsung SDI on them.

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? Vape mod

Great batteries

Just recently bought 4 of these for my geekvape aegis legend dual 18650 mod. I got a good year and a half of usage out of my previous Samsung 25rs (which I also ordered from this site) but these batteries seem to be a good improvement. The 3000mah capacity is great, these batteries last me all day and into the night vaping them at around 60 watts. Although it says they're rated at 15 amps, they perform quite well at 20 amps, however I wouldn't take it any higher than that. Do your own research to find out more.

  • What device/application do you use this with? High power LED

Fast shipping, fair price, great cells

After wasting too many dollars on fake cells from Chinese discount sites I decided to finally order from LIION. I'm really glad I did as each of these tested at a top percent. Capacity was spot-on with a very low internal resistance! I'll be ordering all of my cells here in the future.
