SAMSUNG 18650 30Q 3000mAh 15A Battery



Sorry, this item is out of stock

Newer than the 25R, the Samsung INR18650 30Q has a higher capacity of 3000mAh but a lower continuous discharge rate of 15A. However numerous independent tests have proven Samsung are very much under estimating this figure probably for safety reasons, the 30Q is consistently reaching 20A.

Suitable for a wide range of application in industry and home use and ideal for anyone looking for a high capacity cell with good current discharge abilities suitable for lower powered vaping devices. Its chemistry is a hybrid IMR considered to be the safest, the same as the smaller capacity 25R and has the same prefix of INR. Being a flat top battery of standard 18650 dimensions the 30Q will fit all devices specifying this model type battery, plus run builds or coils down to 0.3ohm safely.

Battery safety is very important. Mistreated batteries can get extremely hot and/or vent which could cause injury. Always follow the following rules to make sure this doesn't happen. We are not liable for mistreated batteries.

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
  • Charge fully (to 4.2V) before first use
  • Never use a lot of force on the battery to install
  • 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
  • Be mindful of the current limits in the specification and never exceed them
  • Never keep a spare battery loose in a pocket, purse, etc. Always use protective cases for loose batteries. If it shorts against a piece of metal it can be very dangerous.
  • Never charge battery 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 battery then do it in a case or individual box in cool and dry place at approximately 3.6V - 3.7V
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for Li-ion batteries.
