With flooded lead acid batteries you will need to make sure the water levels are maintained. So you will want to have easy access to them. Which may limit where they are installed. The second thing is you will be more exposed to the hydrocloric acid solution when maintaining them. So you want to wear protective gear like goggles and gloves. Also any acid solution spilled on your clothes will create holes where the solution spilled when you wash them. Guess how I know.:) AGM's and Lithion do not have these issues.

If I go on the cheap and use the deep cycle type 27 batteries (about $90 each) what disadvantages does it introduce? Sorry for the ignorance but I don't know much about battery difference. Val |

| If doing it on the cheap, (6) 8 volt golf cart batteries in series for 48 volts should give the 2 hours and reserve usage. If not and you have the room, (8) 6 volt golf cart batteries would be more than enough. If you have a bigger budget, then AGM (absorbed glass mat) batteries would be good and can be mounted in any position or if weight is an issue, LiFePO4 cells.

Over the winter I am planning to work on re-powering it with an electric motor. The boat is used for day sailing in the bay and short trips along the NY/NJ shore. Information is available online about motors but battery info seems vague at least to me since I know next to nothing about battery types and their advantages. Does anyone know of any formula that would allow to calculate all the variables to achieve say 2 hours of propulsion and have a reserve? |
