Thanks for all the input.
I know that a true deep cycle is the best choice for a solar setup, but I definitely want a 1-battery system.
I have not found a true deep cycle battery that:
- Has terminals on the correct side.
- Has enough CCA to start the car (3.3L engine, manufacturer recommends something like 620 CCA min).
So, I’m looking at dual-purpose batteries. I have not found a dual-purpose battery with a decent reserve capacity that is the correct size and has the correct terminals (24R/F).
The battery I like (which has the terminals on the wrong side) is a dual-purpose battery recommended for trolling / starting applications and has a large RC.
The biggest problem is that it has terminals on the wrong side.
The solar isn’t installed yet. The current battery requires replacing b/c 1) it’s worn out, and 2) it’s a standard starting battery that won’t work for my plans.
To me, the negative battery cable looks like it’s more of a harness that goes to the back of the engine compartment with several leads going to different places in the engine compartment.
Do you think a longer version of that cable can be manufactured easily? Or is it more a matter of adding an extension to a stock cable?
Thanks for the terminal block idea. I’ll look into that. I think the main issue is the negative cable. The positive cable looks pretty straightforward and easy to replace with a longer version.
I’ve read soldered connections are more brittle in this type of environment b/c they’re rigid and can’t flex with vibrations. Does your experience indicate otherwise?
