Titan Pc Parts

Hi Everyone, I am making a electric Go Kart. I am using a 60v brushless dc motor over volted to 88.8v. I was wondering how I can charge my batteries with a J1772 charger. My Battery setup is: 2x Tattu 12s 44.4v lipo batteries in a series I have two of those series in parallel. I know that I need a 120v ac to 90v dc power supply. I was wondering how I can charge the batteries in the go kart with a j1772 connection. -Josh
