someone suggested to me that if i were to use the propeller to
regenrate power. i would have to have the system in parallel so under
charging mode, diodes could be used to step down the 48v system to a
12 v. because the batteries only start to charge after the generator
has earched the capacity of the batteries.

so to charge a 48 volt system, the propeller would have to spin 4
times as fast to charge the batteries than if its a 12v

i probably didnt explain it very well. but basically dont buy into the
promise of regenration .

Hi,

Might be possible to get a 'linear current booster' or DC to DC
converter to convert the generated ~12v to a suitable 48+V for
charging.

cheers,
Pete.

They do buy into regeneration and have it working
