Ross, I've been hearing about these higher voltage electrical systems that are supposedly just around the corner for probably ten years (or even longer). It makes sense, because the manufacturers keep hanging more and more stuff and accessories on, heated toothbrushes and all that. For some reason they haven't made the transition though.

 

seems like the red top is the way to go. Napa and tractor supply have poor warranties on their batteries. Red tops are 3 years free replacement. They look narrow and long, what do you use for a tie down?

 

Bungee is working for now
