I realize that this thread has some age on it but I have a question about the Quad-cycle unit that has come with a boat I purchased about a year ago. It seems to be working fine at this point but here is my question. To this point I have only had one 12v cranking battery
but I am about to add a house bank. I would like to add for my house bank two 6v golf cart batteries in series connection. My concern is that the Quad-cycle wiring
diagram as well as the front panel of the unit seem to indicate battery
two (house) as being one 12v battery. In the case of two 6v GC batteries in series should this be a problem or will the QC unit simply read the two batteries as one and accurately calculate voltage? I can find nothing about multiple batteries on a house bank in the QC manual which I have read thanks to the google
docs file link listed above. If indeed two 6v GC batteries setup is problematic for the QC I would like to ask if there is such a thing and would it be preferred to go with a 12v golf cart deep cycle battery for my house bank? Thanks in advance...
