[Electric Boats] Batteries

 

I will be installing a 24 volt direct drive system and I am researching my battery options. So many combinations to choose from and wanted to get some feed back from this group and it not just on cost, but safety, longevity, weight, charging consideration, self discharge rates, ect. I was looking for about 200 amp hours and my first thought was 2 4D AGMs but man those 4Ds are big and heavy, the battery boxes for those are also very expensive. The 4D AGMs are also a chunk of change.

Any feedback on Wet Lead Acid, versus AGMs, Gels, or other metal hybrids would be interesting as well as thoughts on 2 12v 4Ds, 4 6 volt, 4 12 volt group 31's (to get the individual weight down).

Thanks

Dave
