These batteries are rated for 240amp continuous, so double will get you 480A.
But you stated you are going to use dual 500Amp controllers (1000A total), so I would be parallel 4 modules, unless you are going to keep the current at a less value.

Or two dual battery packs if you want to keep it in smaller packs for packaging reasons or smaller cabling options which keep the currents down in the buss bars and cables.

Even w/o a BMS you need to monitor the voltages so they don't get to low during use or too high when you are charging. They need a special charger that does CC/CV (constant current/ constant voltage with a cut off). Do not use a lead acid charger or float charger, these type of chargers will guarantee killing the batteries.
