25.2V 4AH 24V 18650 lithium ion battery pack for electric skateboards

Specification

The **NS-7S2P-18650-4000** is a high-capacity 25.2V lithium-ion battery pack engineered for high-drain industrial applications and professional cordless equipment. Utilizing a **7S2P configuration** of high-rate 18650 cells, this pack provides a stable 25.2V (24V nominal) output with a powerful **4000mAh (4Ah)** capacity.

Designed to endure rigorous duty cycles, this battery pack features integrated **Energy Balance technology**, which ensures every cell in the series discharges and charges at the same rate. This maximizes the battery's lifespan and ensures consistent torque for heavy-duty motors, making it a reliable power core for equipment deployed in challenging professional environments.

Targeted Professional Applications

• Cordless Construction Equipment: The primary energy source for portable electric rebar cutters, cordless rebar tiers, and heavy-duty masonry drills requiring high instantaneous current.
• Commercial Cleaning Systems: Powers professional-grade wireless stick vacuums, handheld electrostatic sprayers, and specialized cordless floor polishers used in hospitals and hotels.
• Autonomous Service Robotics: Provides reliable energy for intelligent delivery robots, automated hotel concierge bots, and retail inventory scanning units.
• Advanced Medical Mobility: Reliable power for high-performance electric wheelchairs and portable patient lift systems requiring a stable 24V-25.2V rail.
• Precision Industrial Actuators: Ideal for 24V DC motorized valves, remote-controlled security gates, and automated assembly line pushers.

Core Technical Advantages

1. High-Rate Discharge Performance

The NS-7S2P is built with cells that support high-current discharge, ensuring that high-torque motors (like those in rebar cutters or industrial vacuums) maintain peak performance under heavy load without thermal throttling.

2. Built-in Active Energy Balancing

Our advanced BMS doesn't just protect; it optimizes. By balancing the voltage across all 14 cells, the system prevents individual cell degradation, effectively increasing the total cycle life and ensuring "long-life" environmental sustainability.

3. Compact & Customizable Form Factor

The modular design allows for a **customized size** to fit the ergonomic requirements of handheld tools or the internal chassis of compact robots. Encased in high-insulation PVC, it is both lightweight and shock-resistant.
