SAFETY PRECAUTIONS
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 a Lithium battery, you should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturers 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.
Batteries should be stored carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

Advantages Of EINK
E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
