1. Safety Design For Battery: Use PTC(Positive Temperature Coefficient) and CID(current interrupt device)
2. Safety Design For PCB Protection: Use individual charging protection circuit, protect from over-charged, over-discharged, over-current and short circuit. Assure service life and safety.
3. Safety Design For input and Charging: Use individual management integrated circuits and constant current charging Design, assure safety and anti- explosion, extend battery life.
