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

This power module is specifically optimized for high-torque and high-uptime industrial sectors:

• 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.
