I'm really bad about keeping track of the range and amp draw. I'm not even measuring battery amps. I basically just drive around (look at motor amps) about 35 mph, not more than like 5-10 miles at a time. It's at 72v. Actually right now, I don't even have a controller in the dang car. I still don't have one for myself yet. Only when I have built one for someone else, I drive around for a while until I'm done testing it. But the Synchronous rectification one I'm going to keep I think.
They all still charge up to like 12.7 or 12.8 and stay there. I have no complaints at all.
