You misread René's article, they absolutely will not kill your system. He was highlighting a design flaw - one that will accelerate wear and tear over a long period of time because you're essentially driving the system out of its specification. The entire point was that there is a simple electrical solution to the problem - one that has now been implemented in all of Krikzz's carts that can easily remedy this.
The carts that will damage your system are the multicarts and bootlegs that people have been happily using for years. But whatever I'm sure this is comparable to Terraonion's broken products and miserable customer service.
