This sort of misinformation is typical of companies that manufacture products to fit a market with out having the background experience in that market.
You only need a 30 amp circuit breaker for a cranking battery to on auxiliary battery set-up and a 50 amp circuit breaker for a cranking battery to 2 x auxiliary battery set-up.
Also as posted above, you are far better off just carrying a single jumper lead to bridge between the the two battery’s positive terminals in the rare event that you have to jump start.
Cheers.
