Re: [electricboats] Somebody help Capt. John

The answer to that question has nothing to do with how hard you push your motors, and every thing to do with your wire gauge and fuse size.  If the system was properly installed then your motors top usage draw should be well under the cable gauge used and the fuses should be rated to protect the wires not the motors. Meaning if the system was properly install, then you should be able to run the motor continuously at max load, and the cables if properly sized should stay under the rates sheathing temperature.  

You should measure the length of you Cables to and from the motor controllers and the traction battery. Then note the wire gauge then uses an ABYC wire gauge chart to make sure they can handle the continuous max load draw.  

You can find such charts all over the internet, here is one snatch from google for example: https://www.bluesea.com/support/articles/Circuit_Protection/1437/Part_1%3A_Choosing_the_Correct_Wire_Size_for_a_DC_Circuit
