At EVERY connection? In a 120V lithium pack that 's 38 x 9 = nearly 350W of heat! Sounds a lot and I'm pretty sure my battery box didn't ever get *that* hot! But then, I suppose that would only be under acceleration... my normal cruising current was less than half that but that's still 150W. Still sounds a bit high....? MW
