The new king of high discharge 26650 batteries is this IJOY 40A battery.  This is the best 26650 size battery for high power lights and e-cigarettes and other very high current applications.  The voltage drop is very low at high C rates, much better than any other 26650.  Until now if you wanted this great battery you would have to order from overseas, but we have them in stock in PA.

As always, you can trust Liion Wholesale to have tested random samples from each and every batch to make sure all the batteries are fresh and genuine.  We have an agreement with IJOY themselves and buy only manufacturer direct for these so the chances of issues are small, but we test anyway.  You won't get that with most suppliers.

Warranty:  Satisfaction guaranteed, if your battery is DOA or you think there's a problem with it just let us know within 14 days of your order and we'll make it right.


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.

    IJOY 26650 is a BEAST!!

    The IJOY 26650 is a helluva battery and compares to a roll.of quarters ln size, probably a lil bigger than a quarter's circumference. It seems to have a decent lifespan beore charging is needed and never seemed to lack voktage when needed . I definitely recommend this battery.

    Liion and one other supplier I trust no one else for my authentic battery needs not some others re-wrapps. Fast Delivery and Excellent Customer Service. Only complaint is they need more access to battery cases.
