Yes great care must be taken.
1 I use 2 contactors one on the top of the pack and 1 on the bottom and in time maybe 1 in the middle as well. In the middle of the pack right now I have and Anderson which I unplug any time I service anything or when the car is not in use as I am in the middle of the build at the moment.
But if you want to learn to build 1000+ hp you will never do it with 80v.....
This build I am aiming to break 300hp at the wheels and that would be very hard to do with lower voltages. As well would require the leaf motor to be rewound.
