    LCD screen

    Yep I'm a moron. Needs to be in parallel like any other voltmeter. Forgot because I'd initially planned on using another meter that had amps and had to be wired in circuit.

    Mostly just needed confirmation on the speed wire. Am I supposed to wire this up in line? I have it going battery pos>to controller>controller negative>positive LCD>negative LCD going back to the negative of the battery. The problem is m voltage drops to 43v from 50v when the controller is added...

    Does anybody have info on which wire does what? Don't want to short anything out by connecting things up incorrectly. I really only want to use the speed function and have little use for the other features these things have.

    A Probably Stupid Question About Lacing

    Not in this situation. They're 15mm too short when cross and radially they're probably 5 mm or so too long.

    A Probably Stupid Question About Lacing

    Got back to looking at this to true it and the spikes seem way too long to work. I could probably file a little bit but I think waiting and ordering new spokes would be much stronger due to the reduced number of threads if I file.

    Anybody have photos of it working yet? :)

    A Probably Stupid Question About Lacing

    Managed to get it laced radially. Had to put the heads on the inside of the flange as outside they were too long. Now it seems about a perfect fit. Will work on truing it tomorrow to see. Seems fairly sturdy but I'm imagining ill have to be careful about hard starts and using a lot of torque.

    A Probably Stupid Question About Lacing

    Radial is safe on a 26" wheel at 1000w? I seriously considered it but it didn't seem like it would be strong enough for sure.

    They're about 15mm too short according to the shop. Looks like ill be calling Dan soon

    Lol I bought one last night too. This looks like a nice, cheap CA alternative. Certainly not the same but it ought to work for my needs until I can financially justify a CA

    A Probably Stupid Question About Lacing

    Measured and confirmed with the spokes I had. For the holes, I gently filed just a little to make them fit. I'm just going to take this bad boy to the bike shop tomorrow since ill probably need new spokes anyway.

    A Probably Stupid Question About Lacing

    Well, I can't even get the 4th one to tighten down at all. Guess that would indicate they are too short?

    A Probably Stupid Question About Lacing

    Thanks! I had a feeling the Sheldon Wheelbuilding tutorial had a reason for being like that. Some other tutorial had suggested doing them like this but I was going to try it one spoke at a time like you said this evening. Hopefully it'll all look better when I do things like that. Going to leave...

    A Probably Stupid Question About Lacing

    I'll try that as well. If all else fails, my local shop will do this for me for $45 (+ parts potentially) so one way or another ill sort this. -- Amber, if they seem to be on the short side, would it be best to have them all facing out instead?

    A Probably Stupid Question About Lacing

    I'm only threading a couple turns to make it fit. And the valve hole is good. I'll make sure I'm doing it right as far as the parallelogramism. I've tried reconfiguring things a few different ways so its possible I'm doing it completely backwards at this point. I'll post some better photos this...

    I'm not 100% sure but it sounds like it. Let me know how well that thing works! Looks awesome and cost about what I paid for my wattmeter.

    A Probably Stupid Question About Lacing

    So I got my rim and motor in the past couple days and set about lacing it last night. After seeing ypedals video, I realized I needed to bore out my rim holes just a little to fit these new spokes. So now all the nipples rest in their holes easily but I can only get about halfway around before...

    Desoldering a fet, what am I doing wrong?

    You need to solder that ASAP! Only take a second and will stop you having to replace it again.

    Battery Capacity vs Voltage

    I know this has been discussed on this forum myriad times but finding this site made things very clear for me a while back. http://www.powerstream.com/lithuim-ion-charge-voltage.htm Gives one an idea of capacity and shows the effects of charging to these voltages so you can more easily decide...

    "LiPO", another "be careful" warning...

    Just a simple question. Has anybody ever had a cylindrical actually detonate like this? It was my understanding they have vents like just about all batteries that would prevent catastrophic failure and detonation. Really just curious because the pouches makes sense and I've seen it happen.

    48 volt lifepo4 battery cutting out prematurely

    4.25 is pretty high. I personally dislike exceeding 4.1v per cell and usually stop between 4 and 4.1 and never go below 3.5v if possible with lithium batteries.

    "LiPO", another "be careful" warning...

    The pouches are the only batteries I've seen do this. After a lot of RC vehicles, I've seen quite a few and this is a pretty typical response to hard abuse. Particularly serious shorts or anything that pierces through/a hard drop. I always keep pouch batteries outside as the plume of smoke is...

    48 volt lifepo4 battery cutting out prematurely

    +1 for cement resistors. Those always make a pretty good dummy load if you don't exceed their ratings too far.

    My bike build log

    It was at Walmart and this was all they had. And the peddles were there, just unusable. I'm thinking about the green Kawasaki instead. That has some suspension too. Anybody have any experience with this bike...
