hello everyone!!
I'm currently in the middle of building my own remote control boat.
so I've made the frame, and have the servo's kind of in place and the engine mounted (50cc motor bike engine)
so what i would like to do is install two 12v sealed batteries in series, as i have a 24v 100w 6A 2300rpm electric motor, the reason for this would be to run various electrics like lights and stuff. and well the main reason would be that if the petrol motor was to cut out the electric one could take over and slowly take it back in.
The Question(s)!!!
can i hook up the motor to the batteries without a circuit??
as the electric motor will be connected to the main drive shaft and it will most likely be at a higher rpm than what it is rated (output).
and if i did get the rpm to be just over its rated rpm (so that it will produce more than 24v to charge the batteries... say 25v or 26v) would it need a circuit then?
I initially though it might need a diode to stop the current flowing the other direction, and if so i would program a PIC to detect once the current stops (ie the petrol motor has stalled) to bypass the diode so that the electric motor starts driving the shaft.
also maybe I'm getting a little too ambitious here but once the batteries are fully charged i would think it would do damage to keep forcing current into them, so would there be a way of stopping this and letting the electric motor run with no resistance, as to let the petrol motor run at its best?
okay so that was a bit more that i intended to write, but i hope whoever is brave enough to help can understand it.
thanks to all that have and will try to help!!

ohh, one more thing.
i've worked out the top speed at 100% efficency (obiously it will never happen, espacially if i made the hull lol.) should be about 60mph (100km/hr)
