Made for demanding applications, the IJoy 20700 battery delivers 40 amps of power while maintaining a solid 3000mAh of capacity, all in a size that is only slightly larger than a standard 18650.  The IJoy 20700 is a great alternative to the high drain Panasonic NCR20700A which is extremely difficult to get.

This 20700 high drain lithium ion battery is one of the newer battery sizes on the market, offering the additional capacity and power that enthusiasts need without having to carry  and maintain as many cells. Many manufacturers are starting to explore the versatility and power of 20700-powered devices. 20700 devices are the cutting edge of technology and are designed for folks who demand the highest level of performance with no compromises. Please note 20700 size batteries will not ship with cases.

Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause severe injury or even death.  Always follow the following rules to make sure this doesn't happen.  We are not liable for any injuries caused by misuse or mishandling of lithium ion 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 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.

    • What device/application do you use this with? Device: ijoy Captain / vape at low to medium wattages

    Ijoy 20700 Batteries Rock!

    They are really good batteries. A tad on the bigger side but they just last forever. Perform excellent at high and low wattages. Of course the lower watts just last soo much longer. But totally worth getting if your procucts support 20700 style.
