DIY PCB Circuit Board Welding Equipment Portable 12V Battery Storage Spot Welding Machine Spot Welders Pen For 18650/26650/32650 For welding 18650/26650/32650, etc. Lithium battery, advantages: portable, stable and reliable, and durable. Users need to supply 12V battery power, welding current is about 90A ~ 130A, for the common 18650/26650/32650 0.1mm ~ 0.15mm nickel plated welding. After several generations of product updates, it is now upgraded to automatically trigger the welding, liberating the buttons of the fingers. Power supply requirements System voltage: 12V-14.6V (capacity X rate = 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) Misunderstanding: Don't think that you can use 3 series 18650 series to supply power. After all, the conventional 18650 only has 3-5C discharge rate, so each section can only provide 2.5A*3=7.5A load capacity, which is far from 150A unless 20 Parallel connection, 3 series and 60 sections of 18650 are possible, but it is obviously unrealistic.
