Re: DC to DC Converter
I've just read the article for the first time.
To be clear, you can run both a DCDC converter and an accessory battery together.
The advantages of both are then combined - if the DCDC fails, you are still able to use the 12v systems, as with the battery. The accessory battery can also keep the load off the DCDC converter effectively acting as a buffer between it and the 12V systems.
