So I think I'm going to just go with 4 of these, for $240 plus shipping they should last me a very long time. And if not on this project ill have them for years on other projects.

As long as you pay attention to not letting any of the cells get charged over 3.6V, or discharged below 2.8V, the batteries may outlast the rest of the system.

That's what I figure. And ill only have the panels connected when the radio is on, so current draw will deff exceed the charging current.

Can't wait to fire this up! Might finish construction tomorrow if I have time.

So it looks like this battery is $262 shipped to me. With the nickel connecting bars included.

LiFePO4 Prismatic Battery: 12.8V 40Ah , 12V 40Ah lithium battery

I think I'll just do that. Says in stock too.

Those appear to be the same GBS batteries as I purchased from EVolve.
I like the four screw battery posts better than the single post, but the specs are not as good as the other brand.

Build quality seemed good, only time will tell how many recharges they will do.
Been too cold for me to feel like riding the bike, so have not put on any more miles since post #9.

I like the progress. That thing is awesome...
I am curious to see how the power works out.
I have friends that go on hikes in the desert.
Would be fun to make a solar powered stereo for the back of the suburban
So we can bump tunes while relaxing after the hike...

Thanks man.
Me too! I keeping my fingers crossed that it will be enough to play all out for a few hours. From my rough calculations it should be able to, just depends on how bass heavy the tracks are I guess.

Grills on

Thinking of a grill solution for the 15". Just have to screw the top on, make some kind of prop to hold the top open when the radio is on its side, and inject a little more foam into the cooler between the Baltic birch and the plastic cooler walls.

Impression? It sounds pretty good for what it is! Plenty of bass to go with the midranges, tested to full output and a bunch of stuff was shaking in the workshop, no chuffing from the ports.

I hear a slight buzzing inside the box, gotta insulate some of the wires and plastic stuff inside from buzzing. Maybe it was the cooler walls too.
But basically just finishing touches left for her! I'm excited for it to get sunny and warm here in NY and test this stuff outdoors!
