Battery storage PCB board, 12V spot welding machine, portable battery energy storage board welding machine

Specifications: Material: PCB Color: Black System Voltage: 12V~14.6V Operating Current: 90A~150A Recommended Battery (not included): 20-45Ah lead-acid battery with good performance and low internal resistance; 3S 45C lithium battery; 3S 3.5-5.5Ah lithium battery for model airplanes; 30-35Ah lithium battery. Suitable for 26650/32650 lithium batteries. Package Size: Approx. 190*110*30mm / 7.48*4.33*1.18in Package Weight: Approx. 200g / 7.05oz Note: Spot welding is based on rapid, localized heating and cooling with high current, which requires an adequate power supply. Generally, the welding current for nickel-plated sheet metal between 0.1 mm and 0.15 mm thick is between 90 A and 150 A, so the working current of the printed circuit board must be greater than or equal to 150 A. Package contents: 1 motherboard, 2 input cables, 2 output cables with soldering pins, 1 soldering component kit (tin strips, nickel foil, copper inserts, screws, heat-shrink tubing).
