So my optima failed me ( after 4 years) midway through the year last year. It was a blue top with 750 cca. Basically I couldn’t use my electronics that much because it would just cut off until I started the motor again to charge it some more. So while it’s cold I’m was going to change it up, only problem is I changed electronics as well. I was hoping to try to find the best of my options so I turn to you guys. I have a 05 yami Vmax. And a lowrance HDs 5 at the bow. Now I upgraded to a helix 9 mega at th console, I’m really just looking for something that will crank the battery and the lowrance will run for more that 30-45 mins at a time. Can you guys help?
