    Old tricycle build. Looking for advice. Mac motor?

    I'm looking to turn this old granny trike into an etrike. 24 inch wheels. Got it for cheap and it has nice steel 100mm front forks to work with so I figured it would be an easy project. (bright don't kill me yellow) Most of my driving around town is flat, but I still want good pulling power...

    Skin vs Pavement?

    Too fast for the turn I did do, not too fast for the turn I was going to do. If I didn't have an oncoming suv in my half of the road I would have just widened the turn. Lesson learned though, I'll be going bike speed into any turns I don't have perfect vision of from now on. By now on I...

    Skin vs Pavement?

    Yeah, the guy stopped and asked if I was ok, I knew I had no legal recourse on the matter and just said frock off. I don't want the law involved when it comes to my bike anyway : /

    Skin vs Pavement?

    Pavement wins. Took a bad angle into a corner at the same time an oncoming speeding SUV was dead smack in the middle of the road. So I forcibly dumped myself into the corner vs taking a wide turn into the grill of the SUV. I was in shorts and a T-shirt. I skid for a good distance and I...

    40 mph club

    Ran the bike HOC to see if all my winter mods were going to fall off or not, decided to do a speed run since they just paved a new section of road and wasn't windy. Hit 40.1 then I ran out of road :twisted:

    It is probably on the order of a basic game for a graphic calculator as far as size.

    What is your reason of building ebike?

    Moved from the metro Detroit area to small town OH. I went from having 20-40 mile commuting days (50 RT before that) to 5-10(if I go home for lunch). A few of my coworkers ride year round (probably suspended licenses). I grew up with the dependence on cars being the norm. I've always...

    * * * The 1000 Mile Club * * *

    1000+ on my 48-15ah ping just added a 24v ping to series. Driving period between late april and early october. If not due to BMS problems and bent rims I think this would be at 1500 already. Just contacted my car insurance agent to get a discount for my low car mileage driving habits. :)

    Can I still use Regen with batteries in series?

    2 Pings: 48-15 and 1 24-15 connected in series directly (no diodes) Independent BMS on each battery. Can regen braking still be used? Or will current be dumped into just 1 battery? Btw , bike works again, thanks for the help on troubleshooting the BMS. Joined the 38.9 mph club (so...

    Great bag for Ping V2.5 24v 15ah battery

    I have the medium ibera bag on my desk, accidentally got the medium instead of the large. I didn't like the bag quality so I didn't go for the large.

    Great bag for Ping V2.5 24v 15ah battery

    http://www.walmart.com/ip/Plano-Small-Tackle-Bag-Waistpack/16351070 Plano 3380, enough room for the BMS to breath on top and for some padding to fit between the bag and battery. Plenty of options for wiring and mounting. Fits into a smaller triangle and isn't wide enough to impede peddling...

    Battery click sound, now showing far too low of voltage.

    From Ping He has agreed to replace the BMS for the cost of shipping, and the cost of shipping back the bad one. A+ + , would do business with again. :D

    The fun stops here until I get word back from Li Ping then, I can't start cutting things off the board just in case he wants me to send it back to him.

    Battery click sound, now showing far too low of voltage.

    I don't know what 1 means, it is just want the meter says in diode mode by default. probes touched together the meter emits a steady beep and shows 0. http://imgur.com/QAlCVkg

    Battery click sound, now showing far too low of voltage.

    The black discharge wire is connected to the BMS (P-), regardless if the BMS is connected to the battery through the sense cables, the current has to travel through the Mosfets. If they are causing a problem, wouldn't that give me wrong numbers? If I take the black at (B-) and the red at...

    With the voltmeter in diode mode, 1 is the default reading on the display.

    I also tested my 2 diode packs to make sure the stickers indicating polarity were correct, they are.

    Battery click sound, now showing far too low of voltage.

    A summary of where we currently are. I can get 3.32 from every individual cell except for #16. I assume cell #16 has 3.32 because the voltage from B- to cell #16 is 53.1+ I am as of this point, unable to get any voltage reading by going from the sense cable at cell 16 to the red discharge...

    Battery click sound, now showing far too low of voltage.

    Actually, it is exactly correct. The answer is pretty obvious too. :oops: 39.9 is the total voltage of 12 cells @ 3.32. I was measuring the top of that series cable instead of the bottom, therefore I was getting every cell in that cable instead of just one. Doing it right Cell #1 is 3.32...

    Battery click sound, now showing far too low of voltage.

    I put the black multimeter lead on B- , then the red lead on the first spot of the sense wire. (the very bottom contact in my picture, below the first yellow line) The volt meter reads 39.9 I put the black multimater lead on the last spot of the sense wire, and the red lead on the red...

    Do you take the gate voltage with the sense wires plugged in and the battery on the charger? Or just the sense wires plugged in and the battery off the charger? I did it with the sense plugged in and the battery off the charger

    Battery click sound, now showing far too low of voltage.

    Not sure I am doing this right. I put the black lead into the black discharge, and measured the "bottom tap wire?" which would have been the bottom in my picture. http://i.imgur.com/7GCW4rO.jpg Then I put the black lead on the "top tap wire?" and put the red lead into the red discharge wire...
