Thanks for the input Jim. I'm familiar with the low voltage issues on the DSM300's and have a #6 + and - wire powering nothing but my electronics. The electronics consist of twin C80's, DSM300, 4kw open array radar, VHF, RS125 GPS antenna and TR-1 Autopilot. The run has a total of 14' of cable (7' there and 7' back to the battery bank). Conservatively this cable size and distance is good for 50A+ continuous at 3% voltage drop or less.
The battery bank consists of 2 group 27 batteries paralleled that are charged while running via Bluesea ACR's, one from each start battery. My start batteries are completely isolated and the rest of my house load is fed separately from the house bank. When at the dock all battery banks are charged from a 3 bank smart charger.
Raymarine said as long as it clears itself I'll be fine. Not satisfied with this answer but I'll keep an eye on it...
