flippy said:i expect a lot of oxidation when the nickel, copper and solder/tin are going to have a reaction. dont know by memory but one metal is going to be the sacrifical one.
it also looks REALLY labour intensive. there is nothing to be gained by this method compared to just spotwelding the proper nickel strip or even copper if you can do that.
I want to spot weld nickel strip on battery terminals and I do not find a good one that can carry 22A continuous.
Where did you find the info about the oxidation? I need to check the soldering points of the balance wires on my current battery that was built in 2014.
