Why we choose lithium polymer battery pack for rc products?
Improving Performance: In the RC field, whether it's flying a drone or racing an RC car, reducing weight is of great significance. Lithium polymer batteries are much lighter than other types of batteries, such as nickel-cadmium and nickel-metal hydride batteries. The lightweight nature of lithium polymer batteries helps RC devices become more agile and faster.
Better Space Utilization: The flexible form factor of lithium polymer batteries allows them to be made in various shapes and sizes and fit into tight spaces in RC models. This is very important for the design and miniaturization of RC products, as it enables more efficient use of the limited space inside the device.
Meeting Specific Needs: One of the outstanding features of lithium polymer batteries is their high customizability. They can be shaped and sized in many different ways, so you can choose a battery pack that perfectly matches your RC vehicle. Whether it's a long, slim pack for a racing car or a more cubic design for a drone, lithium polymer batteries can be tailored to specific requirements.
Reducing Downtime: RC hobbyists usually want to get back to using their devices quickly. Compared with some other battery types, lithium polymer batteries generally have faster charge times. This means less waiting time between flights or races, allowing users to have more fun in a short time.
Built-in Protection Circuits: Modern lithium polymer battery packs are equipped with advanced safety features such as overcharge protection, overdischarge protection, and short-circuit protection. The battery management system (BMS) in these battery packs monitors the battery's status and takes appropriate actions to prevent dangerous situations such as overheating and explosion, ensuring the safety of RC product users and their equipment.
Good Chemical Stability: Although lithium polymer batteries are more sensitive to improper handling than some other batteries, under normal use and proper maintenance conditions, they have good chemical stability and can provide reliable power supply, reducing the risk of battery failure during the operation of RC products.
