Randy? Are yu on line still. Talk to us, Sep Ex is a nice way to go. Taking a page from other EV operators, thr Electric RR's where Regen braking has gone on for 100 years or so. Maybe Netgain is working on a motor-controller for this one. They hafta be made for each other, and should come to you in a nice big box, ready to hook up, and go. I don't think there is much purpose built Sep Ex stuff out there, or at least a demand enough to interest a Motor Builder, at this point. COULD work, like Rich Rudman's line of chargers. He created a product that was needed and wanted by the on line EV community, us,.Demand so far, has outstripped supply, of PFC chargers. Hpope he's making enuf bux to stay in supply of tires<G>! OK just a few thoughts on this Sep Ex thread. Seeya Bob > Cheers, > > Roger. >
