I always see a sort of soft start anyway where the initial amps of the 100 might be 99 or 100 and then after a minute it has ramped up to 104a.
The VEC1093DBD starting at 40a setting does ramp up in quick stages to 40.4 too. I suppose this is the battery looking after itself, don't know.
I am so gun-shy about blowing thermistors now, I want to hit the converter with full blast at start up while the thermistor is cold. I am scared that if I started at 13.6 then cranked it to 14.8, when the thermistor is now warm, it would fry. I am pretty sure it would not, and this is a false fear, but I am gun-shy, can't be helped :)
