A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, like mobile devices and radio-controlled aircraft.
“In this video I will show you how I combined a couple of ICs in order to create a charge/protect/5V boost circuit for a single cell LiPo battery. Along the way I will show you how I designed …
“This is a little portable power supply I made a while back, with four very common type-18650 cells (widely available from eBay, despite today’s air shipment regulations).”
