    CCA question

    If you hook batteries in parallel, is the CCA the sum of the 2 batteries or is it just extra capacity of 12v power?

    Two equal 12V batteries wired in parallel remains 12V. Everything else doubles. 2X MCA, CCA, Reserve capacity/Amp hrs.

    that is what i understood from my research. i think i am going to install a crossover battery switch on my lithium batteries like a jumper if i get low on CCA.
