DIY Portable 12V 18650 Battery Energy Storage Spot Welding PCB Circuit Board

Function introduction This circuit will become an energy storage spot welding machine with 12V battery It is used 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 We have customers By replacing the thicker wire 10 square can barely weld 0 2MM thickness After all this device is geared towards electronics enthusiasts and the frequency of use will not be very high so 0 1 0 15 welding 2 can also be used to replace thicker nickel sheets Button function The button can switch modes each mode corresponds to different welding time LED corresponds to red green blue white yellow pink purple 7 modes the red time is the shortest and the purple welding time is the largest Long press to set the waiting time the default is 3 seconds the maximum can be set to 10 seconds Basic parameter Power supply voltage 12V 16 8V capacity X ratio must be greater than 150A Current requirement greater than or equal to 150A instantaneous output such as car starting power supply 3S model high rate battery pack 12V lead acid battery with good performance above 20A Packaging included 1 X PCB Circuit Board
