You know, light

Maybe someone can do the math how fast you would have to be going?

That is correct. 1 battery for the engine and 2 for utility. I guess it has to be quite a beefy one. The interter is rated for max 166 amps. So that’s quite a bit. Which also makes it a bit hard to find a suitable relay.

Is an extra utility battery. So that shouldn’t give any issues for starting. That’s a separate battery. I’ll try to find one of those relays. I know I can search myself but if you have any suggestions they are always welcome:)

The issue is that I cant place two of the same batteries. The extra one has to go under the passenger chair so it will be a completely different battery. I’m not completely sure that we won’t be running into issues then when linked in parallel.

I agree that the relay option it’s added complexity and finding the right relay is a bit of a challenge haha. Also there probably will be a short drop in voltage or I have to switch them shortly after each other. So both relays are closed at the same time for a little bit. I don’t know if that would fix the arcing? It will be linked in parallel for a little bit then I guess.

Unfortunately I’m not a UI designer or UX expert:/ Blogs/wiki is an idea but then you would need ideas what to write about. In my dayjob I quite like helping coworkers with a specific problem to figure out what’s the problem or what the best solution would be. I’m not sure how I can convert that to helping the community then
