Mooch’s Notes:
  • At 10A continuous this cell delivered almost 2850mAh. This typical for a high-performance 3000mAh cell so I am rating it at 3000mAh.
  • Its temperature of 78°C at 30A continuous is the average for cells being operated at their rating so I am rating this cell at 30A.
These are high capacity and high discharge current batteries. If mishandled / mistreated, they can cause you SERIOUS INJURY. USE AT YOUR OWN RISK !

Safety Notes:

  • Do NOT short.
  • Do NOT use if battery appears damaged or the wrapper is ripped.
  • Do NOT leave unattended when charging.
  • Do NOT leave unattended immediately AFTER charging.
  • Do NOT carry in your pocket or purse unless they are in a secure non-conductive carry case.
  • They are not toys. Do not let your children or pets play with them.
  • Do NOT recharge with cheap chargers that keep on trickle charging after the normal cycle or that do not follow the Constant Current / Constant Voltage (CC/CV) algorithm properly.
