Hi, I read the following somewhere on the net
"Even if the open circuit voltage produced by the turbine is
high, the battery will hold the system voltage down to its own level."
I would have imagined that this applies to even a small battery such as a 3.7V button cell battery, but iv been looking at circuits that use a dynamo to charge a 3.7V cell battery, and they seem to be using an Adjustable Regulator to limit voltage and current, could someone please give me an insight into this.
Thanx
