Warnings
- Li-Ion Batteries may explode if charged or discharged improperly.
- Please possess knowledge of electronics 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.
- Please read more safety warning about Li-ion battery
