Hi folks
It's very windy where I live - there are two huge offshore windfarms and the hills are studded with turbines. S0 I thought I'd make a small wind turbine for experimentation.
I have 36 18650 cells that are rejects from my ebike battery pack build because they only have 900-1400mAh capacity left, but that's enough to build a 12v 12A 3s12p battery bank to connect to a wind turbine.
The turbine I am building will use a small permanent magnet dc motor from a Ryobi 18v cordless drill if it proves suitable after some testing to see what volts it outputs at various rpms.
What electronics do I need to connect the turbine to the battery pack - would it be best to employ balance charging?
