How Lithium-ion Batteries Work

They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would. If you completely discharge a lithium-ion battery, it is ruined. A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
