Re: [Electric Boats] Schematic or diagram of system help

 

I am actually installing the same system and using 2 banks as well.. The advice I received from a good source is to make two separate banks and then hook them in parallel.
  To get the batteries to discharge evenly you need to use the same length of wire between the batteries.
  The runs that connect the batteries to the switch and the motor also have to be identical lengths on both banks..
  What you are looking for is equal resistance so it could actually be done with different sizes of wire but that would require a lot of calculation to get the resistances of the wires right its way easier to just use length and go up a wire size if yo u are worried about  the overall resistance

Chaplain on Deck:

I am new to this forum and am converting my 1974 Cal-29 to electric. I just purchased the 100ibl motor through electric yachts. I am getting 8 US AGM 31 batteries to power the system and have a question. Should I make two banks of four or connect the two banks in parallel? If anyone has a schematic or diagram on how to hook up the system – your input would be wonderful!

Also, if you have any advise - so far we have decomissioned the diesel engine and fuel tank, and have cleaned and painted the engine space. What should we do next?

I will post some photos...
BTW – Mike at www.electricyachtssocal.com has been GREAT, as well as Scott at www.electricyacht.com/
