Battery question

[Mr_Bucket]

Would this be enough for a superjet with two 500gph bilges: autozone.com/miscellaneous-non-automotive/motorcycle-and-power-sport-battery/duralast-gold-powersport-agm-battery/350077_0_0/?OnetoOne=true&searchText=Etx12

Trying to find something on short notice with limited space and not sure I want to go the lithium route...

That is a 10 amp/ hour battery. Assuming you bilge pumps draw a combined 3-4 A (depending on load), and your charging system supplies 1.5-2.5 A (depending on rpm), you can probably ride all day before the battery needs an additional charge.

Will 180 CCA be enough? The lithium one I had was 360, but I've also seen people on here who say they're using batteries with as little as 120 CCA.

180 CCA is plenty, our Tampa riders use 120 CCA Deka 9's no problem. I ran a little 5 battery once on a 855 motor and it would start it in the water and work if you were easy on the bilge pump switch.
