Genuine Samsung 29E 2900 mAh batteries are a battery cell designed mainly for e-bikes and hybrid vehicles and similar applications.  Although the continuous rating is low at 2.75A, they actually handle 5.5A very well, and 8.25A fairly well.  The ratings are very conservative on this battery for sure.  For example this battery has more capacity than the 25R at 8.25A even though the 25R has a 20A rating.  We still don't think this battery would be appropriate for most vaping/e-cig applications other than low wattage ones around 25W per battery or below but is one of our most popular for high current pack building applications.

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.
