Default Re: How to hook up a battery to my bike generator

some ganerator produce AC. if it is you need to change it to DC. The output voltage will go up and down depending how fast you are going so you need to buffer it with a large capacitor and regulate it to 2 -3 Volts above the baterry you want to charge. insulate it with a diode to prevent it from drawing current form the baterry when charging voltage is too low. check out regulator IC 7805, 7812, or LM317. they are quite easy to use.
