Aideepen | 6x18650 Lithium Battery Welding-Free Diy Kit Dc Ups Power Supply Optical Modem Router Uninterruptible Power Supply 5V 9V 12V

Description:1. Solder-free design allows users to freely disassemble and replace batteries2. Features DC equalization UPS functionality for automated charge/discharge management without manual intervention3. Multiple output options covering common voltages (5V, 9V, 12V) for devices like optical modems, routers, and surveillance cameras4. Rigorous quality control ensures long-term stable operation and extended service life5. Stable performance with peak output power up to 60WProduct Specifications:Battery Capacity: 63.7V3400mAh = 74Wh (Batteries not included)Rated Output Power: 12V5A = 60W; Actual output depends on battery capacityOutput Voltage: Independent outputs: 12V 3-5A; 9V 1A; USB 5V 2-3A. Enabling UPS function requires meeting input power conditions.Product is unregulated; batteries output voltage directly in series, which fluctuates with charge level.Suitable for high-power devices requiring no voltage regulation: motors, LED lights, audio equipment, solenoid valves, printers, etc.Compatible Batteries: 3.7V cylindrical flat-top 18650 batteries (power-type batteries recommended)Charger Type: Internal charging current-limiting circuit; chargeable with 12-13V adapters. Higher input power provides greater stability when used as a UPSCharging Power: Input adapter power must meet ≥ total load power + battery charging power (6W)Overcharge Protection: 4.25V3Low Voltage Protection: 2.75V3Overcurrent Detection Voltage: 0.1V ± 0.025VTemperature Range: -20~60℃DC Connector Standard: DC5.52.1mm (Positive Inside, Negative Outside)Important Notes:1. Spring connects to negative terminal, copper tab connects to positive terminal. Do NOT reverse polarity—reverse connection will cause burnout!!!2. Use high-quality batteries and ensure strict pairing. Each individual cell in the battery pack must have as consistent parameters as possible.3. This product is only compatible with flat-top 18650 batteries. Pointed-top batteries longer than 2mm cannot be used.Package Contents:Solderless Battery Case10.3m Cable*1
