Charge battery with bike dynamo Answered

Hello,

I would like to charge a battery using my dynamo on my bike.
The battery I would like to use for my head and tail light for example and for charging my phone.
Would this be possible and how?

Thanks in advance

My hub dynamo is Shimano DH-2N30-E (6V 2.4W)

I don't know yet what kind of battery to charge. Maybe a 6V lead battery?

What dynamo do you have? How much voltage and current can it produce and at what RPMs do the wheels need to be moving at to achieve that power? What kind of battery are you looking to charge.
