Smooth Control, Silent Power – PKNERGY Lithium Battery Solutions for Smart Curtain Systems

1. Why Batteries Matter in Smart Curtain Systems

The global smart home market continues to grow rapidly, driven by innovations that combine automation,
energy efficiency, and user comfort. Among these, smart curtain systems have evolved from luxury add-ons
into essential components of modern buildings. They regulate light, privacy, and temperature with seamless
automation. Behind their elegant operation lies a crucial component—the battery system that enables wireless
and uninterrupted motion control.

Smart curtains must operate reliably throughout the day, responding to commands from apps, voice assistants,
or automatic light sensors. Because many installations are wire-free or retrofit systems, they rely on built-in
rechargeable lithium batteries instead of direct AC power.

PKNERGY’s Li-ion and LiFePO₄ battery solutions are engineered to deliver the high energy density,
stable voltage, and long cycle life required for these compact automation systems. Our custom battery packs
power quiet motors, controllers, and wireless communication modules while maintaining excellent standby performance.

2. Technical Highlights

For smart curtain systems, PKNERGY provides tailored lithium battery modules with the following specifications:

• Voltage Range: 7.4V / 11.1V (2S–3S configuration)
• Capacity Options: 2000–6000mAh depending on motor torque and duty cycle
• Cycle Life: ≥ 1000 cycles @ 80% DOD
• Self-Discharge Rate: <3% per month
• Safety: Built-in protection circuit (PCM/BMS) with overcharge, short-circuit, and thermal control
• Communication: Optional integration with RS485, BLE, or Zigbee modules for smart monitoring

These batteries are compact, lightweight, and designed to fit seamlessly into motor housings or controller compartments,
eliminating the need for external power cables and enabling truly wireless smart curtain designs.
