The simple answer is to put as much battery in as possible given your available space and displacement. In a Darby, a 12volt 25ah battery wouldn't be out of place at all.
I'd avoid the wet cell batteries and go with a sealed lead acid or equivalent... |

First you need to figure out what the motors and other items need. That will tell you whether to go 6 or 12. Then work out the biggest you can carry in the space available. As said before, avoid wet automotive types - they are inclined to vent acid fumes all over the insides of the boat with bad results for anything metal. SLA or Gel cell battery.
I look at battery information sheets that sellers should show to get the dimensions and make card mock-ups of likely candidates to see what fits, then I can do try-out ballasting with that weight where the battery will go to see if its going to float properly. |

Battery
The motors have tags on them stating the voltage they are designed to run on. check the type of speed control and google it-them to get their operating info.
Nice boat. Bob |
