Features:1. The product is free of welding, the user can freely disassemble and replace the battery2. With DC isovoltage UPS function, realize automatic charge and discharge management without manual participation.3. Multi-functional output, covering optical cat, router, surveillance cameras and other commonly used 5V, 9V, 12V three voltages4. Strict quality control to ensure long-term stable operation and prolong service life.5. Stable product performance, peak output power up to 60WParameter:Installable battery capacity: 6 * 3.7V * 3400mah = 74 watt-hours (battery users to provide)Rated output power: 12V5A = 60W; the actual output power from the battery itself output powerOutput voltage: independent output 12V3-5A; 9V1A; USB5V2-3A; enable UPS function need to meet the input power conditionsThe product is not voltage stabilized, the batteries are connected in series and output directly, the voltage increases or decreases with the amount of power.Suitable for high-power appliances that do not require voltage regulation, electric motors, LED lights, stereos, solenoid valves, printers, etc.Applicable batteries: 3.7V cylindrical flat 18650 batteries (recommended power battery)Charger type: internal charging current limiting circuit, can be charged with 12-13V adapter, when the UPS is used, the greater the input power the more stableCharging power: input adapter power to meet >= total load power + battery charging power 6WOvercharge protection: 4.25V3Low voltage protection: 2.75V3Overcurrent detection voltage: 0.1V+-0.025VTemperature range: -20~60°CDC interface standard: DC5.5*2.1mm (inside positive and outside negative)Precautions:1. Spring to the negative pole, copper to the positive pole, do not install the reverse, install the reverse will burn!2. The use of high-quality batteries and require strict pairing, composed of battery packs of each individual battery should be the same parameters as far as possible!3.This product can only use flat 18650 batteries, pointed batteries longer than 2MM, can not be used!Package include:Welding-free battery box * 10.3 meters line *1
