That depends on how much energy you want to pull out of the batteries.

For the most RVs the 500A shunt should be enough.

500A x 12V = 6000W

Thanks Matthias, then I know that the size is enough.

The problem itself os that I now have connected 2 x 200Ah-a batteries on parallel, but the shunt only gives less than 200Ah with every consumption I have tried.


Any ideas on where to look for the problem?
