Everything would be great if only one of the pins wouldn't be defective. The round end was stamped incorrectly. Solder flooding not possible. AND Also standard 50mm2 hydraulic cable shoe press doesn't correctly crimp the 50mm2 wire into this 50mm2 cable lug. Cable is loose after crimping 5x. Reason - walls are very thin. Therefore after crimping with smaller hydraulic press walls will NOT hold the strands with force as required to pass such current (look at the other side cable lug). So the only way is to solder everything together. That requires extremely powerful burner because 50mm2 wire passes heat too well. Also wire insulation must be heatproof. I used NSGAFÖU cable and it worked. Seller is good, refund accepted.
