YX850 Automatic Power Switch Module – 5V-48V Wide Input, 10A High Current, UPS Backup, Supports 18650 Battery, Ideal for Raspberry Pi/Router/CCTV/Emergency Lighting!

Key Features & Benefits：

✅ Automatic Power Source Switch: Automatically switches to backup battery (e.g., 18650) when main DC input fails, ensuring continuous operation

✅ Wide 5V-48V DC Range: Compatible with 12V, 24V, 36V, and other low-voltage systems, highly versatile

✅ Handles 10A High Loads: Supports 10A continuous current for routers, CCTV cameras, lighting, and more

✅ Compact & Ready-to-Use: Only 61×30×18mm size, easy to integrate into Raspberry Pi projects

✅ Smart Charging Control: Automatically powers load and recharges battery when main power returns

✅ Supports 18650 Battery: Can use common 18650 Li-ion cells as backup power, economical and convenient

Product Description：
The YX850 module provides an economical and reliable automatic power switching solution for DC systems, especially suitable for non-critical equipment that can tolerate brief switchover interruptions. It supports 18650 battery backup, making it the ideal guardian for Raspberry Pi projects, network routers, CCTV cameras, emergency lighting, and DIY projects, automatically activating battery backup when main power fails.

🚨 Critical User Guide & Notes (READ BEFORE USE)：

Switching Delay Notice: Module has a brief power interruption (~0.3-0.5 seconds) during switchover. NOT suitable for equipment that cannot tolerate any power break, such as computers, servers, etc.

Voltage Matching REQUIRED: DC Input, Battery, and Load MUST be at the same voltage (e.g., all 12V). This module does NOT convert voltage.

Power Priority: DC Input has priority—powers load and charges battery. Battery only powers load when DC input is off.

Charging Parameters: Charging current is determined by your DC power supply; module only controls the switching path.

Installation Tips:

Ensure all connections are secure with proper wire gauge

Recommended to add a fuse in series with main input (choose based on load current)

Install in well-ventilated area, avoid high temperature and humidity
