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.

    Great Product again

    I came back to Li-Ion batteries for this amazing 18650. My second pair shipped quick. This battery can handle more then 15A with out raising temps that bad. I would not reccomend more then 20A or higher then 18A for long duration. Not sure if this has to do with LI-ION or Samsung, but the white protective ring at the positive end that is under the wrap was way off center on one of my units. I was able to move it some what back to its place. The battery mah of 3000 lasts me 2 days at 80w.

    The real deal

    These batteries we're all checked and tested and they are infact the real deal. Never had any issues they all do what their claimed to do btw 15A.. lol more like 20A. Don't last quite as long as my doo doo LG HG2's it seems (CoV Temptest 200w ran at 140W using 3 batteries with a tfv8 cloud beast and T8 coils) but their fantastic and a bit cheaper by about 50 cents a unit. They do seem to perform a lil better tho aka they dont start to sag until im down to like 10-15% vs 15-20% with the LGs Shipping was CRAZY fast like seriously FAST placed my order @ 6pm or so oct 31st they shipped by 9am the next day (nov 1st) Definitely look foward to ordering more from Liion. Just got to find a way to hide it from my wife. Next order will probably be 25 batteries or more.. lol..
