Lithium Polymer

What is a Lithium Polymer battery?

A Lithium Polymer (LiPo) battery is a rechargeable battery that uses a polymer electrolyte instead of liquid electrolyte found in traditional lithium-ion batteries. LiPo batteries are popular in RC vehicles, drones, and portable electronics because they offer high energy density, lightweight construction, and can be manufactured in flexible shapes and thin profiles. They typically provide 3.7V per cell and require specialized charging circuits due to their sensitivity to overcharging, over-discharging, and physical damage.

A Li-ion (lithium-ion) battery is a rechargeable energy storage device that uses lithium ions moving between positive and negative electrodes to generate electrical power. These batteries are widely used in portable electronics, electric vehicles, and maker projects due to their high energy density, lightweight design, and ability to be recharged hundreds of times. Li-ion batteries typically operate at 3.7V nominal voltage and require specialized charging circuits to prevent overcharging and ensure safe operation.
