Any updates?
I see a lot of people complaining about the 12v battery longevity on Priuschat, and I wonder if it could be replaced entirely with this "boostpack" supercap/battery combo.
I'm still curious if the frequent cycling of the alternator would cause more wear, and even more curious about the efficiency of charging capacitors/LiFePo vs a lead acid battery. Specifically, what percentage of the input charge is captured and stored, and what is wasted. Self-discharge rates would also play a role in the overall efficiency.
Do supercaps self-discharge at higher rates than regular capacitors? I realize the answer will vary depending on what type ( electrolytic, etc).
