INR21700-40P High-Rate Lithium-Ion Battery Features:
Ultra-High Discharge Capacity
Instant High Current Output
Low Internal Resistance
High Power Performance
Strong Durability
The INR21700-40P High-Rate Lithium-Ion Battery is a premium-grade cylindrical cell designed for power-hungry applications such as electric mobility, cordless tools, energy storage systems, and industrial equipment. With a nominal capacity of 4000mAh and continuous discharge rate of up to 10C, this battery delivers stable power output, exceptional thermal control, and long cycle life.
Manufactured by Zigong JOINSUN Technology Co., Ltd., the INR21700-40P is engineered using high-quality raw materials and advanced lithium-ion chemistry, ensuring excellent safety, low self-discharge, and superior current performance.
Application of INR21700-40P High-Rate Lithium-Ion Battery
The INR21700-40P lithium-ion cell is specifically engineered for high-discharge applications, offering consistent performance under heavy loads. With its 4000mAh capacity and up to 40A continuous discharge capability, it meets the demanding power needs of modern electric systems. Below are the key industries and applications where this high-rate battery excels.
1. Electric Mobility (E-Mobility)
The 40P cell is widely used in:
Electric bicycles and scooters
Electric motorcycles
Low-speed electric vehicles (LSEVs), such as delivery carts and warehouse AGVs
Benefit: Higher energy density means fewer cells per pack, reducing weight and improving efficiency.
2. Cordless Power Tools
Drills, impact drivers, saws, grinders
Industrial handheld devices
Battery-powered construction equipment
Why it's ideal: High discharge rate (up to 40A) ensures instant power burst and sustained runtime.
3. Energy Storage Systems (ESS)
Residential solar battery backup
Portable power stations
Modular battery banks for smart homes
With long cycle life (≥1000 cycles), the 40P cell is well-suited for deep-cycle ESS usage.
4. Smart Agriculture and Electric Farming Tools
Battery-powered sprayers and tractors
Irrigation controllers
Field monitoring devices
Rural and remote areas benefit from its reliability and low maintenance needs.
5. Outdoor and Off-Grid Power Solutions
Camping power banks
Emergency backup batteries
Portable solar generators
Lightweight and compact design makes it ideal for mobile applications with demanding power needs.
6. Military and Tactical Equipment
Military radios
Unmanned ground vehicles (UGVs)
Night vision and surveillance gear
Military-grade applications require high reliability, extreme temperature resistance, and fast discharge – all supported by the INR21700-40P.
7. Aerospace and Low-Altitude Economy
Drones and UAVs
Electric aviation prototypes
Aeronautical instrumentation
Lightweight yet powerful, the 40P cell helps reduce payload stress while maximizing battery life.
