  • The end user must have the technical knowledge necessary to charge and discharge Li-Ion batteries before making Li-Ion Battery Packs
  • You must use a protection IC ( PCB) to keep the battery and its packfrom over charging and over discharging.
  • Please read more safety warning about Li-ion battery
  • Batteryspace.com is NOT liable for any mis-use due to any other brand of PCB applied
  • California residents: Warning: Cancer and Reproductive Harm - See Prop 65 Warnings
