Re: [EVGRAY] charging a coil like a cap [1 Attachment]

Body

Thanks for the explanation Kone on the chargers.  Batteries love that
flyback energy and can apparently supply more current faster once
conditioned this way.  I have heard once conditioned to the flyback
after about 10 or so charge discharge cycles they can become very hard
to use with a conventional charger for awhile as they have to be
conditioned back to normal if one wishes to use with forward current.

Maybe the Rene allows the batteries to remain somewhat normal and not go
totally flyback conditioned, therefore less volume of current avail but
better compatibility.

Size of coil and core influence the fly back pulse strength along with
the length the core goes beyond the coil in order to act as a B field
antenna.  Try a short piece of rebar core compare to a long one for
shits and giggles.
