Hi Everyone,
I currently have two batteries on my 305, but want to use those as dedicated starter batteries and add house battery capacity (~400RC). I found it rather confusing to figure out which battery was the best for this application, so I made a spreadsheet:
https://docs.google.com/spreadsheets...#gid=672549354
It looks like interstate AGM is current the best bang for my buck. My questions:
1) is my spreadsheet taking into account all of the important factors
2) Are there any battery manufacturers I need to add to my list?
Notes:
-I take into account the difference in depth of discharge (DoD) for acid vs agm vs lithium
-I take into account i'll need 2x 6Vs to make a 12V system
-I do not take into account that lead acid requirement more routine maintenance and handle vibration worse
-I do not take into account the actual cycle life, just assume each battery has the same cycle life for a given DoD. For example, it assumes lead acid at 50% DoD has the same cycle life as AGM at 80% DoD.
-I boat in Lake Superior and will maybe cycle these things 20-50 times a year, so the theoretical large cycle count capacity of lithium is not really worth it to me.
Thanks!
