We don't think this will be a major issue. One of the nice things about LiFePo4 batteries is that it has an enormous cycle life compare to lead-acid and can provide a really high level of power throughout its entire discharge range. The power of lead-acid degrades pretty quickly and you can have significant trouble cranking your car even if it still has half of its energy available. If the electronics were using high enough amounts of energy to be a concern for our design, it would also likely mean that the cars would have trouble starting with a lead-acid.
