Bike aux electical design help.

Basically I am building my new bike for touring and thus need a few accessories to run. The problem is that I want to have an auxiliary battery in one of the hard cases to power the gadgets as I want to be able to run them even with the bike off without the fear of draining the battery. I also want to be able to control when the aux battery charges or discharges.

Will this schematic work, or will I burn out the bikes charging system when I connect the batteries together?

i think you'll be better off just getting a larger capacity battery, rather than wiring in another one. the devices you have listed will run off the battery for a good while (minus the hair dryer) without causing the battery to drain enough to not start the bike, and even if you did drain it, you can still push start the bike to get it going again.

There is no space to fit a battery any larger. Its pathetic - the same battery as on my old Ninja 250

ya, its been awhile, but I think when running batteries in parallel, the voltage is the same across the circuit. but then again, i'm a civil engineer, and most of us hate electrical circuits.

i'd have to sit down with a pen and paper to figure it out...i'd seek out a RV forum.

Looks like an isolator is the way to go. It looks like it is a must to use identical batteries as well.

Or you could just rewire the whole bike and go to a 24v system by running them in series

...don't forget to put some JB Weld on your oil drain plug so it is easy to remove the next time you change your oil.

Thanks, I just read up on those. I hope they are not too large in size.

Interesting idea; but I wonder if you could just purchase a higher-capacity stator to relieve the load on the electrical system. Whether you need to run the bike ever so often to recharge the battery would be a problem then.

personally, i think you should just wire in a 12v outlet and call it good. what do you plan on running for a long time that would drain a battery?

Take your helmet off and get some real wind blown hair.

Ham radio. It consumes 1amp on standby and up to 12amps on transmit.
Then I have aux lights, cellphone, gps, heated vest maybe.

What kind of bike do you have ??? They have high output kits you can get for guys that run a sh*t load of electronics

Check out this myspace a lot of Busa Guys do this becuase they have Turbos and need the extra juice for all the electronics they run ... Good Luck
