Jay, Wow, only 10volts sag on a +41kw (+350amps times 118volts) of power, that is pretty amazing!!
Forgive my ignorance: so each module is at 8volts? (16 in series, total 128V pack) (each Leaf module is 60ah correct?) Which BMS and charger are you using? Do you have a website or similar where to see some pictures of your work? Congratulations.. Saludos..!
