Features
– Can be welding 18650/26650/32650 lipo battery, it is portable, stable and reliable
– System voltage:12V-14.6V
– Working current:90-200A
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
-This circuit with a 12V battery will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries. According to different configurations, the thickness can be about 0.1MM-0.15mm
Notice:The 18650 battery and DC power cannot be used as a power supply. It must have a high rate RC battery or a car battery!
Power Requirements
Spot welding is welded by the principle of rapid local heating and cooling by high current. Need sufficient current supply , generally 0.1-0.15 nickel plated sheet welding current about 90-150A , as the working power of the circuit board must be greater than or equal to 150A.
The following battery packs can be used as working power
12v car starting power supply , 3s high-rate battery pack for model airplane ,three-string high-rate lithium battery pack , Hitachi 40900 3-sting battery pack,lead-acid battery with good performance above 12v 20A .
Calculation Formula
capacity x discharge rate = load capacity
Take 3000ma aeromodeling battery as an example . the discharger rate is 45C (3.0X45C=135A)
Button Instructions Description
Each time you press the button, the power increases by one level. LEDs 1-5 indicate that the power is from small to large, 1 is the smallest, 5 is the largest, and the LEDs are all off to turn off the output
Package Included
1 x DIY Portable Battery Storage Spot Welding Board
