Using get_posts, I need to use a combination of OR & AND relations

Using WordPress v4.6, I set up arguments for get_posts() based on price (2 conditions), sku, and categories like this:

[meta_query] = Array
    (
        [relation] = AND
        [0] = Array
            (
                [key] = _price
                [value] = Array
                    (
                        [0] = 0
                        [1] = 5
                    )

                [type] = DECIMAL
                [compare] = BETWEEN
            )

        [1] = Array
            (
                [key] = _price
                [value] = Array
                    (
                        [0] = 50.01
                        [1] = 100
                    )

                [type] = DECIMAL
                [compare] = BETWEEN
            )

        [2] = Array
            (
                [key] = _sku
                [value] = batte
                [compare] = like
            )

    )

[tax_query] = Array
    (
        [0] = Array
            (
                [taxonomy] = product_cat
                [field] = id
                [terms] = Array
                    (
                        [0] = 26
                        [1] = 20
                    )

            )

    )

I set AND relations, but actually I need OR relations between 2 prices and AND relations for the rest of the comparisons.

What is the correct syntax for this query?
