Thread: Dual Batteries and Fuses...

Hi again sam, as pointed out above, those current figures you posted would be for the devices own power consumption.

Next, do not even consider fitting a 150 amp circuit breaker to anything in a vehicle unless you plan to run sub station thick cable as there would need to be a load of over 225 amp for around an hour before the circuit breaker tripped.

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.
