Overcharging, short-circuiting, crushing, puncture, overheating, or physical damage can cause fire, burns, or serious injury. Observe the published limits for 4.20V maximum charge voltage, 2.50V normal discharge cut-off, and the stated charge/discharge temperature ranges. Stop using the cell if the wrapper, can, or terminals are damaged. Important Usage Guidelines: Use Only with a Compatible Li-Ion Charger / BMS Do Not Exceed 4.20V Charging Voltage Do Not Discharge Below 2.50V in Normal Use Observe Charge and Discharge Temperature Limits Spot Weld Only – Do Not Solder Directly Do Not Use if the Cell Wrap or Can Is Damaged
