If I were to make this a permanent solution, I would likely run 1500F capacitors instead of the 350s. The kit on Ebay is $209.

I am also considering reducing or eliminating the current limiting resistor so that the LiFePO4 can contribute more to starting the vehicle.

My third idea is to connect the battery to the capacitor with 2 parallel connections. 1 connection would have a current limiting resistor to reduce the rate of charge. The other connection would have a power diode that would allow the battery to supply cranking amps (at a 1v reduction), but not allow charging through that connection.
