Rally cars place a lot of strain on batteries. Usually we use a pretty substantial battery , which is heavy. We also seek to lighten up what we can.
In the racecar world, there has been some movement to Lithium batteries to decrease the weight of the battery. I don't know if there is a Lithium battery that can supply the needs of a rally car. The real point of this is a cautionary tale.
I was at a racing event a couple of weeks ago that had an incident. A racecar that used a Lithium battery had the battery catch fire. I couldn't be extinguished. Lithium batteries have magnesium as one of the components. A normal ABC or BC bottle that we carry in a car will not put out a Magnesium fire. It requires a class D bottle to put it out. The point is that is better to carry a bit of extra weight that to risk a fire that cannot be extinguished.
