  • Li-Ion Batteries may explode if charged or discharged improperly.
  • Please possess knowledge of electronic and understand how to handle Li-ion battery. 
  • Please always use a protection circuit board (PCB) to keep battery from overcharged and over-discharged
  • Never solder directly onto the Li-ion battery as overheat might damage the battery. 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.
