3.7v Lipo Battery A lithium polymer battery, or more correctly lithium-ion  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 one. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide a higher specific energy than other lithium battery types and are being used in applications where you need a long backup and you want to power up your electronics gadget for a long time like ESP32 , Wemos d1 mini or Arduino's.
