Sell DIY Portable PCB Circuit Board 12V Battery Energy Storage Spot Welder Machine shbarbie best price

Specifications: Can weld 18650/26650/32650 lipo battery, it is portable, stable and reliable System voltage: 12V-14.6V Working current: 90-150A Suggested battery: 20-45ah Lead-acid battery with good performance and small internal resistance 3.5-5.5ah 45C 3S aeromodel lithium battery pack 30-35ah capacity 18650 battery pack Power supply requirements: It is forbidden to use the power supply of the farad capacitor, and it is forbidden to use the lead acid battery or lithium battery pack of 60A or above. 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. Package Included: 1set x Energy Storage Spot Welder Machine Notes: The colors may be a little difference for the different monitor display. Please allow minor deviation due to manual measurement.
