Three light setup for studio and outdoor portraits

[ndwgolf]

I currently have 2 x Profoto B1 Heads that are 20+ years old, I have replaced the batteries twice already and they are starting to play up again so rather than buy more batteries (bloody expensive at that) I'm thinking if getting a new Godox AD600BM II as a key light plus two smaller lights for Hair and fill light The Godox AD600BMII is B17668 Thai Baht about £400, all my modifiers are Bowens mount which is what Godox uses.......... when shooting outdoor portraits I normally only use one off camera flash so the hair and fill lights don't necessarily need to be battery powered.
Any recommendations ?
