Need to slow it down a little.

LiFePO4 packs are even worse about soaking up all the alt power they can get, due to low internal resistance compaired to lead acid.
Uncontrolled charging is not recomended. Slower is better (less really is more in this case).
So this is really important, as I move toward trying to create a plug-in and solar external power combination to keep my alternator off nearly all the time. I need to replace the battery I seem to have ruined with deep discharges (live and learn). I'll go larger this time, and might directly imitate brucepick's design described in this thread. Can I get a single power controller that would regulate charging of the larger deepcycle second battery from all of three inputs, solar panels, the alternator, and plug in? I imagine yes, but I am unfamiliar with the hardware.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
