The one battery ends up costing $58 after shipping.
They do have a two pack for about $89 and free shipping
I was tempted to buy a couple more, but I’ve got 9-10 DeWalt 5 amp batteries now.

I’ve been buying a pair of Dewalt 5 batteries on Amazon with a charger for about $150. I have plenty of chargers now.
