DC contactor for 350A at 90V

[Apal]

Hello,
I’m trying to build my first electric go-kart, but I got stuck with a dc contactor. Because I can’t find any suitable for my battery pack. My battery pack will have voltage from 60V to 87.6V, but I only found dc contactors that have maximal rated contact voltage at 80V, are those 7.6 more volts big deal? I’m not really experienced with dc contactors and relays.
This is the best I found: www.aliexpress.com/item/4001100527661.html
