    2012 eFXC/TTXGP Australia - Rd 1 Wakefield Park

    Thanks Chris We did it with a water cooling system Jon designed, it worked great it was a spray system triggered by heat and the blowers keep the water evaporated. With heat under control we can up the current, as the motors are still not near core saturation. After the race without charging we...

    Jason accidentally pulled the cord tied to the emergency switch shutting off the motors tomorrow will be better and faster he did not run out of battery

    Used a BM6 to monitor the indivdual cells and as a low voltage alarm so if i got any cell going under 3.5 volts i terminate the test.

    Here are plots of some of the packs The variation I attribute to temperature. some were done at 55 to 60F and others at 65 to 70F

    To me they are the best deal going, not that this is the only good Lipo Solution to building a larger battery pack, there are many

    I charged them to 4.2 for the test, but in everyday use it'll be 4.1 to 3.6 volts. I'm totally happy with 4.7 AH capacity for a first power cycle. I expect they may even get a small amount better once cycled a few times. I can't wait to get the ThunderJunk (Thundersky) cell out of my bike.

    permanent parallel its going to be So far the packs are showing at 1C 4.7 AH with a cutoff at 14 volts I'll show the plots later I've charged about ten of them and they all are 2/3 charged and balanced out of the box - very balanced so far so good

    Wiring not the issue for me, it'll go fast, its the pretesting I have to do before the wiring begins that's a time killer i do have it so the test can be done unattended but of course I'm in the room/shop while they are being tested and charged. Having a CBAII helps

    That's a lot of voltage I've only purchased the cheap 20C packs

    I've been buying turnigy for almost 2 years now and have not had your kind of failure rate. Of the 50 packs or so I've purchased (none hardcase) I had two packs fail one with a zero volt cell and one puffed and had low capacity. The one that puffed I may have damaged with a heat gun. But...

    Got 50 hardcase 4S 5000ma 20C packs today all the cells checked out at 3.79 to 3.85 no dead cells This will all become a 8P 24S pack 100 volts @ 40AH maybe more if I also use other packs i have around

    Good! Someone finally oil cooled a hubbie!! HS3540

    Yes we have had our own flooded liquid cooling program testing begins testing next week. All feed through are solid copper in epoxy that transition back to stranded wire before exiting the motor. the seal lip ride on a outer aluminum sleeve not epoxy as the picture appears. since this picture...

    change the heat sink electrical insulator to better one?

    I agree nylon screws are a mistake. If you have to take shrink tubing and put it over the threaded part of the screw that might/can touch the tabs, use two layers. Also split lock washers are useless bevel washers are a must for top performance. Get them from Mcmaster Carr Edit: I just wanted...

    Ebike or Emotorcycle?

    Thing is on a bicycle going 113 Km/h is a one time scary event one brags about. On a E motorcycle I jump onto the highway and do it almost every day. To brag about speed on a E-motorcycle you have do over 300 Km/h. Just saying its like comparing apples and oranges there both round but the...

    It's a shame what happen to Chris, you can never predict what will happen in bike racing. On a positive note: Catavolt took the pole position in the first qualifier http://www.computime.com.au/meetings/2011/FX_5/FX11_5_Q01.pdf The first race saw Ripperton turn up the current in his motor...

    I mentioned on this race thread that Catavolt would benefit greatly from Lipo as Jon bike is using headway cells. I was thinking the Catavolt bike could lose 150 pounds with Nano-Tech Lipo over headway for the same voltage and AH rating. That's a lot of tin cans

    Terrific racing Great work guys Jon needs some magic to turn those heavy Headway cells into light weight Lipo "OH YEA that's called money"
