First question for me may require more information but, I'll try to frame it well.
My Tiffin Phaeton 40IH feeds power from the chassis batteries to the merge solenoid in the house battery compartment. The merge solenoid has several functions which are not relevant to my question.
This feed is less that 30' of 3/0 cable. I take power from that side of the merge solenoid to a 12v to 12v 30amp DC2DC charger. Power from it is fed to a battery bus bar where my LiFePo4 batteries connect. Ground is achieved at the factory ground bus bar.
One problem is that I am getting more than 1.5v drop and sometimes as much as 1.8v.
Power is supplied from both chassis batteries through a 600am fuse at their location.
How can I reduce voltage drop?
Thanks, David
