  • To reach max capacity of 2800mAh, please charge the battery to 4.30V. PCB with 4.30V cut-off must be applied.
  • Li-Ion Batteries may explode if charged or discharged improperly.
  • You must 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.
  • You must use a protection IC (PCB) to keep battery from overcharged and over-discharged
  • 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.
