DIY Portable 7-16V High Rate Lithium Battery Energy Storage PCB Circuit Board (Single Board)

Features: -Function introduction: This circuit with 12V battery will become an energy storage spot welder for welding nickel plates such as lithium batteries and nickel-chromium batteries. According to different configurations the welding thickness can be about 0.1mm-0.15mm. By replacing the thicker wire (10 square) it can barely weld 0.2mm thickness. -Key functions: The keys can switch modes each mode corresponds to different welding time LED corresponds to red / green / blue / white / yellow / pink / purple 7 modes the shortest red time and the largest purple welding time. Long press to set the waiting time. The default is 3 seconds and the maximum can be set to 10 seconds. -Power supply voltage: 12V-16.8V (capacity X nification = must be greater than 150A). -Current requirements: 150A or more instantaneous output (such as car starter power supply 3S RC high-power battery pack 20A lead-acid battery with good performance above 20A). The 18650 battery cannot be used as a power supply. It must have a high rate RC battery or a car battery!
