I bought the Gasbike Gen for our motors I can make it produce light but how do I get it to charge a 12Volt 1.3AH SLA Battery? I would like to make my own battery charger if I can. Can anyone help?
I already posted in your other topic about this but what the heck.
You bought this on e-bay for $45 right?
It's an iron bar wrapped with copper wiring like this one on e-bay for $30.
Pass a magnet over it, and it generates a little AC pulse.
The faster you pass a magnet by, the more power it makes.
Put DC to it and it becomes an electromagnet.
In short, transfering energy from magnetic to electrical and back again.
To save whatever little power that coil can make you need to convert it to DC and I'm thinking 12V 1ah is a bit optimistic and maybe think 6V.
Most anything even 7.2V LED's will handle 6V DC.
It is all what your second coil can produce, and I figure that little coil won't produce much.
How much power that can produce is directly related to engine RPM.
The higher the R's, the higher the voltage.
The voltage of your battery determines how much voltage the source has to have (RPM's) to if it's high enough to actually charge as you can't charge a 12V battery with a 6VDC source.
A full wave rectifier (ac/dc converter) is just 4 diodes, you can buy the packaged version for $1

I'll get back with you when I have some time.
