Warning

• CAUTION: when working with Li-ion cells, they are very sensitive to charging characteristics and may explode if mis-handled.
• User should have enough knowledge on Li-Ion rechargeable batteries in charging, discharging, and assembly before use.
• Put the batteries in fire-proof container
• Do not put batteries on wood surface or carpet when charging
• Never leave battery un-attended when charging
• We are not responsible for damage if there is any modification of the batteries in form, shape, or made into packs
• We are not responsible for any damage caused by misuse or mishandling of these Li-Ion batteries
