Hi All,
Has anyone installed or read a dual battery install where the primary purpose of the aux battery is as an emergency cranking battery, secondary to powering fridges etc (which the AllRounder is capable of).
Installs I've searched/found either have fuses/breakers either side of the isolator, or no fuses/breakers at all.
I agree having fuses/breakers inline is the correct (preferred) way to install but they will prevent the aux from crank assisting due to the aux battery CCA being higher than the rating of the fuses/breakers. Of course, raising the rating of the fuses/breakers defeats the purpose of having them.
However, having no fuses/breakers is generally a big no no, due to the damage that can be caused.
So the question is, how can the system be wired to enable aux CCA to flow back to main without melting the isolator that enables the charging of aux to occur?!
Any ideas? Gratefully received.
Note: My understanding is RedArc Start Assist appears to equalize the main-aux voltages which will be of no use if the main battery is degraded and unable to produce the CCA required.
