Self-heating too. Looks great.

I found the Insight has the same behavior, where the DC-DC varies its voltage. One can change the DC-DC's target voltage from 14.4 to 13.8v by cutting one wire, and disable the voltage variation by cutting another (so it will stay at 13.8). If one wanted to get more clever, a 5v PWM signal allows complete control over the DC-DC output from 13.8 to 15v.
