Sounds about right. Just make sure your spot welder will do it and you'll have no problems

Be Careful!!

I will double down on HumanPerson's comment. 0.15 inch is over an eighth of an inch thick. The endcaps on your battery are less than 1/16th inch thick. So spot welding heavier metal to lighter metal can be a challenge. It may involve using successive layer of thinner material spot welded to the layer underneath.
