Try it without ventilation first. Drive it around for a while then quickly stop it and check the temperature of the Victors. If you cannot hold your fingers on them, they are too hot.
The tote has a fair amount of surface area. Heat will pass through the walls to the outside. The plastic is not going to be a good conductor of the heat but it may be good enough. You may want to install one of the large fans that comes in the KOP to circulate the air inside the tote. The more driving around you do, the more heat the Victors will dissipate. This is offset by the air flowing over the tote as you drive. Some of the smaller AC motor controllers (under 50hp) we sell at work get put into large, totally sealed boxes due to the dusty environment they are being used in. There are formulas for calculating the size of the box needed based on the heat generated by the motor controller, the surface area available to dissipate the heat and the ambient temperature.
