What type of battery is typically used in electronic systems for rockets?

Lithium Polymer (LiPo) batteries are commonly used in electronic systems for rockets due to their high energy density, lightweight nature, and ability to provide high discharge rates. These characteristics make them ideal for applications requiring significant power in a compact form. In rocketry, where managing weight and ensuring efficient power delivery to systems such as avionics, altimeters, and recovery systems is crucial, LiPo batteries stand out.

These batteries also offer versatility in shape and size, allowing for easier integration within the rocket design. Additionally, they can be charged and discharged many times with minimal degradation when proper care is taken, making them a cost-effective choice over time.

In contrast, other battery types like Nickel Cadmium, Alkaline, and Lead Acid have their own specific uses but may not provide the same combination of lightweight energy density and performance required in the demanding environment of rocketry. For example, Nickel Cadmium batteries tend to be heavier and are often subject to memory effect, which can limit their usability depending on the application. Alkaline batteries are generally heavier and not rechargeable, while Lead Acid batteries are significantly heavier and bulkier than LiPo batteries, making them unsuitable for most rocket applications where weight is a critical factor.
