Yes I would agree. At our plant sites, we use electric golf carts for all of our construction projects. They all had a key switch to power up, and a rocker switch for forward and reverse.

It would be pretty unusual not to. Couldn't you connect that to a relay with its NO contacts in series with the contactor coil, so the contactor would always be open when the "ignition" or key switch is off, even if the BMS wanted it on? The problem seems different for a portable battery supply. There I guess I'd probably look for a different BMS, one that doesn't insist on controlling the main contactor. But I am not a lithium expert.
