Moving to an 8 volt system

Sean’s recent speed trials have us thinking the motors will run more efficiently with an 8 volt system.  Since this won’t be an issue with the rest of the electronics (we already use a voltage regulator), and not a problem for the PV system (we can charge at 10.8 volts with 3 parallel sets of 3 panels in series), the decision is made.   The keel will now contain 5 lead acid, 8 volt, 3.2 AH, batteries from our friends at batterydirect.com

Kiddie Pool Test

Ok, we’ve got all the pieces talking to one another and a nice stable boat.  Tomorrow is our speed test so I thought we should wet test it first. The motor speed took a bit of adjusting.

For those of you who use Google Earth, you can see the Elk Lake Course
