  • After discharge at 10C for 6 mins, the temperature reaches 65°C. Suggest to have some cooling method when building into battery packs.
  • Batteryspace.com is NOT liable for any misuse due to any other brand of PCB applied 
  • Li-Ion Batteries may explode if charged or discharged improperly.
  • The end user must have the technical knowledge necessary to charge and discharge Li-Ion batteries before making Li-Ion Battery Packs
  • We must use a protection IC (PCB) to keep the battery and its pack from over charging and over discharging.
  • Please read more safety warning about Li-ion battery
