Product Features:1. The product is lead-free, allowing users to freely disassemble and replace the battery2. Equipped with DC constant voltage UPS functionality, enabling automatic charge and discharge management without manual intervention3. It features multiple output functions, covering three common voltages (5V, 9V, and 12V) for devices such as optical modems, routers, and surveillance cameras4. Through strict quality control, ensure long-term stable operation and extend service life5. The product features stable performance with a peak output power of up to 60WProduct Parameters:Maximum battery capacity: 6 * 3.7V * 3400mAh = 74Wh (Battery not included, user to provide)Rated output power: 12V5A=60W; actual output power comes from the battery's own output powerOutput voltage: Independent outputs of 12V 3-5A; 9V 1A; USB 5V 2-3A; UPS function activation requires meeting input power conditionsThe product lacks voltage stabilization, with the battery connected in series for direct output, causing the voltage to fluctuate with battery charge levelsSuitable for high-power appliances that do not require voltage stabilization, such as electric motors, LED lights, audio systems, solenoid valves, and printersApplicable battery: 3.7V cylindrical flat-head 18650 battery (recommended for power applications)Charger Type: Internal current-limiting circuit, compatible with 12-13V adapters. When used as a UPS, higher input power ensures greater stabilityCharging power: The input adapter power shall meet the requirement of being greater than or equal to the total load power plus the battery charging power of 6WOvercharge Protection: 4.25V * 3Low-voltage protection: 2.75V * 3Overcurrent detection voltage: 0.1V ± 0.025VTemperature range: -20 to 60°CDC interface standard: DC5.5*2.1mm (positive inside, negative outside)Notes:1. The spring contacts the negative terminal, and the copper plate contacts the positive terminal. Do not reverse the installation; incorrect installation will cause burning!!!2. Utilize high-quality batteries and enforce strict pairing requirements, ensuring that each individual cell in the battery pack has as consistent parameters as possible3. This product can only use flat-head 18650 batteries. Sharp-head batteries with a length exceeding 2mm are not permitted for usePackage List:Solder-free battery box *10.3-meter line * 1
