I have bought this circuit board in order to finally carry on an old wish : - to spot weld batteries. Unfortunatelly, at the same time, I have also bought two supercapacitors of 3000Farads, that were not sent out, due to the fact that seller was out of stock. This was and continue to be a big trouble, because I have cancelled the purchase of these capacitors, it was accepted, but until now Ali has not properly refunded me. This all because a seller decided to sell what he does NOT have. This became a common issue on Ali, without any visible solution (seller should be, immediately, banished). After all the test of this circuit will only be done after I purchase new ultracapacitors.
