    Speaking of these, I managed to melt my pack a few months ago while charging it manually. Thermal walkaway. Does anyone have a spare pack, pack lid, or something like that?

    Found the reason my Enjoy with contactor control was cutting out; the contactor I grabbed was old and bad. Replaced with a newer one (36v from Elec-trak) and now I have even more motor power. Which brings up a thought: I've noticed a few people burning out the gears in their box. Is this a...

    No, I didn't see that. Kind of makes sense actually; even with 14 gauge wire from the batteries to limit current this thing has a lot more power. Finally got the tire replaced and took it out for a ride. I must have a weird controller because I was driving it all over the place and the battery...

    Hill: Yes, using a normal relay would be bad; the contacts would weld and there would be no way to easily stop the bike. That's normally defined as "bad". Oddly enough most cheap Chinese controllers use a FET to do the switching and when they fail, they fail shorted as well. Fun. The problem...

    Well, this just keeps getting odder. Today I took what was left of my dead controller, hooked it up to my 24 volt bench supply, put 12 volts (midpoint on a +12,-12 supply) on the yellow wire, wired together the blue/white wires, and BEEEP! Turned the voltage down to 21 volts, did the key...

    So I posted way back in the fall of last year about my Enjoy's controller being dead. Spent the winter fiddling with it, never got it to work. This morning I went out to the shed, looked at the bike all in parts and said to myself: "It ain't gonna fix itself..." And got to work. First was the...

    Dr.Bass Steveo found 7s3p Module! Awesome Price!!

    For starters: I am only an egg :-) That said, I've been working on the A123 cells for about a month now; what interests me about these packs is *not* the cells per se, but the wrapping around the cells. The aluminum sheets, the end places, the plastic routing bars, and whatnot are far more...

    Interesting thread here, glad there are some people still riding these bikes. My enjoy had it's controller apparently die last fall. Odd, one day it worked, next it didn't. The battery pack is good, however there's nothing with the key turned. It is pulling current from the battery with key in...
