The NS-3S4P-18650-10400 is an industrial-grade 11.1V 10.4Ah (10400mAh) lithium-ion battery pack specifically designed for smart medical ventilators and critical respiratory care systems. In 2026, medical ventilators require not just high capacity, but intelligent power management to ensure patient safety during transit or power failures. This battery pack utilizes a 3S4P configuration (3 Series, 4 Parallel) to deliver a high energy density of 115.44Wh in a compact footprint.

As a specialized supplier from China, we focus on extreme reliability. Our ventilator batteries are built with original imported cells from world-leading brands—including Sanyo, Sony, Panasonic, Samsung, and LG—or top-tier domestic medical-grade cells, ensuring maximum cycle life and stable discharge curves for life-sustaining equipment.

Technical Specifications

Engineering for Healthcare Excellence

1. Smart RS485 Communication & Telemetry

In a modern smart hospital, a ventilator must “know” its battery health. Our integrated RS485 communication protocol (with optional SMBus/I2C) allows the medical ventilator to monitor:

• SOC (State of Charge): Highly accurate percentage for estimated runtime.

• SOH (State of Health): Predictive alerts when a battery needs replacement.

• Real-time Telemetry: Voltage, current, and cell-level temperature data.

2. Multi-Layer Medical-Grade Safety

Patient safety is paramount. The internal Battery Management System (BMS) incorporates industry-leading protection logic:

• Temperature Protection: Active thermal monitoring to prevent overheating during high-demand ventilation.

• Short Circuit & Over-current Protection: Immediate isolation to protect the ventilator’s internal turbines and control boards.

• Overcharge & Over-discharge Protection: Extends the service life beyond 500-800 cycles.

3. Modular & Scalable Design

Our modular battery design allows for flexible integration. For high-flow critical care ventilators requiring longer autonomy, we can design multi-parallel or multi-string combinations. We use a standardized “PACK” unit approach that ensures high consistency across all 12 cells in the 3S4P array.

Specialized Application Scenarios

While optimized as the core power source for Smart Medical Ventilators, this 11.1V 10.4Ah battery is ideal for various high-stakes professional fields:

• Respiratory Care: Transport ventilators, neonatal ventilators, and home-care CPAP/BiPAP backup systems.

• Medical Systems: Portable ultrasound, ECG monitors, defibrillators, and automated infusion pumps.

• Intelligent Robotics: Medical service robots, disinfection UV-robots, and laboratory automation AGVs.

• Industrial Support: High-precision field instruments, remote data acquisition systems, and industrial sensors.

• Emergency Response: Portable radios for first responders and outdoor mobile medical carts in regions like Germany, Turkey, and the UK.
