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