Yes the idea is to de-load the alternator. I've already worked out the details for switching the alt off electrically by interrupting the field wire (Civics have an unusual 5-wire circuit,and none of the 5 is a ground). My commute is a bit over an hour each way so I need some significant capacity to cover that.

LeFePO4 really only likes a 20% discharge?? That's my concern with the AGM. Wouldn't be much different if I used a FLA deep cycle, I don't think. For any lead-acid, I think I could discharge it down to ~20% but just not very often. LiFe could discharge that far all the time, I thought?
