    Even Newer 4 to 24-cell Battery Management System (BMS)

    you would want to use a 'isolation transfomer' Which is basically a 1-to-1 transformer. You put in 120V and you get out 120V. But the advantage is that the two circuits (input-to-output) are electrically isolated just like any other transformer. Thus there is no common ground when you put such...

    2 wheel drive DH bike build (Delta/Wye Upgrade)

    Believe me, Extracycle is not that much heavier. Since the xtracycle makes the trailing arm a lot longer, even rough terrain seems very smooth as the shocks need to move only a little bit to engulf big pebbles. The long wheel base also helps in stability. On a normal bike, if the rear wheel...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    So the conclusion, was .... IF you WEAR a helmet, you still end up with a fudgy head. And you suffer all your life. IF you DONT wear a helmet, you probably die, AND get a economy-class ticket to heaven. Not bad, i suppose... Right now I need to wear a helmet.. (found out yesterday)I also...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    One thing tested. I won't survive another crash. But the 12g spoke probably will :shock:

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    Warden, that is one awesome post you have up there. Next time I am going with motorcycle spokes ... period. Btw, if you have time, could you just snap a quick snap(with cellphone, or a camera) of your trailer hub with the 48 spokes. I just wanted to see how it looks like with the lacing. I...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    48spokes on a cystalyte? or just on a normal wheel? I was thinking how you can manage to space 48 spokes. Do you re-drill them? I agree 100% that the crystalyte rim is ABSOLUTE rubbish! Next time I am going to buy the "atom lab's Pimp rim" people say that they are the strongest.. weighs 740g...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    Thats how they do it everywhere.. at most bike shops(i guess) .. Thats How I saw spokes get threaded at Justin's place(Ebikes.ca), and Courtesy Bicycles (located in WIndsor,ON,canada) If you look at the spoke threader, there are three rollers made of hard-steel, with existing threads on them...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    What I was trying to see was there is a 200lbs load limit on the Xtracycle. I was thinking, that load limit is probably due to the how much a normal wheel can withstand. Whereas we have 12g spokes, fatter axle, stronger rim(i guess), and fatter wheel; THUS the actual limit of My bike would be...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    I normally have my tires at 25psi.. a lot lower than most tires. I have full suspension but that only helps me, not the passenger. IMAGE OF THE CYCLE : (large 4MP: http://fayazkadir.com/blog/wp-content/uploads/2010/06/Ebike.jpg The passengers are all unsprung mass. So (today) what I did was...

    12G SPOKE + 3 PEOPLE +130Nm = BAD

    One 12g spoke+nipple would probably cost around $1.5. The bulge happened first. Destroying the rim. A single spoke would be definately cheaper, but I would say "good luck" if you want to re-use your old spoke on new rim. First of all, they are rusted. they are not made of stainless steel. Its...

    Btw, before anyone reads anything... Is there anyone else who broke their 12g spoke on the crystalytes? Please answer below, inorder to make me feel better that I am not the only person who suffered My Rim got damaged recently. Broke a 12g spoke on my crystalyte kit. Btw, 12guage is almost...

    50kmh indoors!

    Next time I will post a video with my wrist watch on the side of the CA.. that was a quick video at 3am in the morning, so had no clue that someone might say "it was accelerated" There was another video of the same hallway at 70-something kmph. I was asked to removed that from one of my youtube...

    Even Newer 4 to 24-cell Battery Management System (BMS)

    I never had the issue of the BMS blowing.After Charge I always disconnect the BMS. and only Dicharge them my 9Ah, or till 72V (3V for each cell). I have seen the weakest cell to be 2.94V and the supercell to be at 3.11V, others were at (~3V) when I was exactly at 72.1V resting voltage. One...

    Even Newer 4 to 24-cell Battery Management System (BMS)

    I use 15 Pin Sub-D connectors. Among the 15 pins I only use 12 of them for each 12 Cells. This gives me an option of not replacing the whole connector if one connection pin is broken. These are slightly different connectors. Normally in the D-connectors for serial, the wires are exposed and...

    Lipo Video

    I had mine burst in flames. But it was bound to burst into flames after the way I treated it.. 3S1P lipo, hooked up to 4 of fully charged 55Ah SLA.. thats 48 V vs the 12.3V of the pack... I guess just before the flame burst, if every cell was considered same, they were getting 16V each.. I...

    Thundersky Charging Efficiency

    Sometimes, When I travel to work and only use up 1Ah~ of the capacity, I would set up my charger at 200mA CC, so that over 5 hours it charges up slowly. when I would come back after 8 hours, I would see 1.3Ah being pushed back in to the battery. Thats 30% more than it was used. Sometimes the...

    How hot can a brushed motor get before destruction?

    If the brushes are cheap, and someone wants to squeeze a bit more power :twisted: , i don't think brush life would be a factor.. 8)
