Joysun offers a diverse range of battery options for all types of FPV drones, with discharge rates 3C ~ 200C. Both LiHV and standard LiPo chemistries are available.

Industrial UAV

Industrial drones are UAVs designed for professional operations. They are typically larger in size and mostly multi-rotor, featuring a payload mounting structure underneath and tall landing gear. These drones demand high levels of protection and extended flight endurance.

Joysun provides high-energy-density batteries for this type of drone, with a maximum energy density of up to 550 Wh/kg, enabling significantly longer flight times.

Radio Control model

RC model batteries represent a very broad product category. They cover remote control cars, boats, aircraft, robots, and more, characterized by an extremely wide size range and a high degree of DIY flexibility.

Joysun primarily provides power solutions for electric RC models, offering cost-effective customization options ranging from 3C to 200C, along with batteries in a wide variety of sizes and specifications.

Humanoid robots

Humanoid robots have become a hot topic in recent years. Joysun provides highly customized pouch cell battery solutions for this type of robot, featuring specialty cells with an energy density of over 400 Wh/kg and a low risk of thermal runaway.

Car Jump Starer

A car jump starter is a common emergency tool for drivers. It is primarily used to power a vehicle's battery, and typically integrates multiple functions to handle various situations that may arise on the road.

Joysun's car jump starter delivers reliable discharge performance even at -20°C, and integrates an air compressor, flashlight, phone charging, BMS, and more. It is the ideal travel companion for drivers.

Home Energy Storage System

A home energy storage system is a battery solution designed for off-grid backup power, solar energy integration, and peak shaving and valley filling. It typically features an all-in-one wall-mounted design or a modular stackable configuration, with a total capacity that can reach 20 kWh or even higher.

For home energy storage systems, Joysun offers integrated energy storage cabinets as well as customized solutions.
