How do I hack Kobalt 80V batteries

[Affable Pilgrim]

I already own 3 Kobalt 80v batteries but they have no adapter like DeWalt 1800w Portable Power, Milwaukee MX FUEL Carry-On, and Ego Power Nexus Portable Power Station. Does anyone know how to hack these batteries and what it would take to hook them up to an inverter? Any thoughts or advice appreciated.
