1. It can be used for welding 18650/26650/32650 and other lithium batteries
2. Portable, stable, reliable, durable, and low cost. You have your own car starter battery or high-power battery pack, just connect it and you can use it! Save production cost
3. You need to bring your own 12V battery for power supply, and the welding current is about 100A-200A. It is easy to weld the common 0.1mm-0.15mm nickel plated sheet. Please make sure that your battery can have a current greater than 100A, otherwise you will not be able to weld
4. Power supply voltage: 11.5V-14.8V
5. Working current: 100-200A (the best current: 150A, discharge below 100A, it will not work)
6. A battery with a large discharge current will directly affect the welding effect. The following batteries are recommended:
-36-45ah Lead-acid battery with good performance and small internal resistance (internal resistance is less than 10 milliohms, discharge current is greater than 100A), such as a new car starter battery
-4000mah 35C-8000mah 30C 3S model airplane lithium battery pack
-30-35ah capacity 18650 battery pack
