Rechargeable 3.7 Lithium-ion Polimer Battery 502035 300mah
Product Description
Lithium polymer battery, shorted as LiPo, LIP, Li-polymer, lithium-poly among others, is a type of rechargeable lithium-ion battery that use a polymer electrolyte instead of a liquid one, made possible by the use of high conductivity semisolid (gel) polymers. Lithium polymer batteries has many unique features that make them highly suitable for many applications. One of their most significant advantages is the form factor. This kind of battery is lightweight and can be made into almost any shape you want, providing flexibility for device design. This is particularly useful for consumer electronics like smartphones and laptops where space and design are key factors. Additionally, they have a lower chance of suffering from electrolyte leakage compared to their lithium-ion counterparts, as they use a polymer electrolyte instead of a liquid one. The safety profile is further enhanced due to their robustness against overcharging. Moreover, they have a low self-discharge rate, which makes them a convenient option for many electronic devices.
