  • Li-Ion Batteries may explode if charged or discharged improperly.
  • Please possess knowledge of electronic and understand hot to handle Li-ion battery.
  • We reserve the right not to sell and void the warranty it you don't meet the above statement.
  • Please use a protection IC (PCB) to keep battery from overcharge and over discharge
  • Never solder directly onto the Li-ion battery as overheat might cause battery to explode. If you are making a pack or need to solder batteries together, you need to get battery with tabs on it. You will solder to tabs instead directly onto the battery.
  • Please read more safety warning about Li-ion battery
