Safety Cautions:

• Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage if they're not properly recharged or used.
• Do not reverse the polarities when recharging or discharging the battery. Do not use an inferior charger/charging panel to recharge the battery.
• Do not mix old batteries with new ones, and avoid using batteries of different brands.
• When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
• Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reach their max cycle life, or after working for over two years, whichever comes first.
• Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
