The one boat I received (Clear Skimmer RCBoat) which is more of a smaller scale simple boat has individual batteries and that is not really something I wanted. The boat claimed it came with batteries and a charger, but when it arrived, I saw that it required 6 AA batteries.

The wiring is small and appears to only have 1 black wire soldered to the battery and wired to the circuit board. There is another black wire on the other end, but it runs to the lights on the boat. I am not sure if the wire leading to the light would complete the circuit as a 2 wire setup. As there is a wire that leads off of the lights and back through the boat. I haven't followed the other light wire to see where it leads.

My question is, is it possible, well fairly simple to convert this to a 9.6v battery pack?
The wires of a 9.6v battery pack are generally thicker and are gauged different. The wires on the boat are rather thin. So I don't want to fry any wires with running a heavy gauge wire, even though it would be nearly the same volts.

Hope someone can help. I'm not sure if the Clear Skimmer is sold here, sorry if thats an issue.
Call it a newb error
