I'm reaching out to inquire about the total cost for 2 units of a specific battery system, which includes the required battery management system. I'd like to ensure that the pricing covers everything: product cost, shipping, taxes, and any potential fees. We want the items to be shipped to Canada, specifically to the postal code J3L6B6. Please provide a detailed breakdown of the total cost and estimated delivery time. This information will help us make a timely decision. Looking forward to your prompt response!
