Has anyone had experience with the inner workings of regen braking. I am designing my own controller, with variable regen braking (done by PWMing the flyback FET at low duty cycle), firstly is this gonna work? the internet told me it would :P Secondly, what sort of currents will flow into the battery and is it possible to cause any damage, im running lead acid AGMs so i wud expect them to tolerate it better than others. I also have decoupling caps on the motor driver so it should take all the voltage nastys out before the betteries "see" them.

I'll let you know when I get done with my project (my controller is supposed to have regen).
But I hear mixed reviews coming from people I've talked to. A lot of folks that I talked to said that the regen on their controllers (I think that they were referencing the Sevcon Millipak PMAC) was "so-so." I am not sure what that means. I am assuming that they got the batteries to recharge somewhat, but that recharge rate wasn't really substantial.
I know that's not of much help but I am still a newbie trying to learn the game :)
