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 reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery. Do not mix use old batteries with new ones, 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 reaching their max cycle life, or working 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. The 18650 batteries are NOT included Please note that the battery length SHOULD be less than 67mm, some batteries with protection plate in the market are NOT supported, learn more UPS Module 3S x1 XH2.54 male self lock button switch ~15cm ×1 XH2.54 male to DC5521 female cable ~15cm x1 XH2.54 dual connector cable ~15cm ×1 XH2.54 male to Type-C cable ~20cm x1 Acrylic protection panels x1 Screws pack ×1 **12.6V 2A Battery Charger x1 - This has a US Plug
