    EL GIXXER rides again

    I never re-created my Project thread after the El Moto v1.0 crash, but since I just got it licensed, it's time to update. (Most of this stuff can be found in my blog, but honestly who wants to wade though all that.)

    Start Date: Summer of 2008
    Chassis: 1991 GSX-R 750
    Motor: D&D ES-15A-6 series wound DC
    Gearing: 68/12
    Controller: Alltrax AXE-7245
    Body Work: 1990 GSX-R, and misc others
    Battery Trays: 3/16" 5052 aluminum sheet bent on a home made brake
    Motor Mount: 3/8" 6061 aluiminum stock, cut on CNC plasma cutter
    Traction Batteries: 50 Headway 40160 cells arranged in a 25S2P pack (~80V)
    Battery Frame: 3D printed PC-ABS blend
    12V system Batteries: salvaged B-B SLA's
    BMS: None. Riding bareback and manually balancing. Tedious, but enlightening
    Curb Weight: 433 lbs. This is 20lbs lighter than stock.

    Before (ignore the trashy garage) / After

    Thanks for the kind words all, and for keeping the elmoto fire lit when I needed some motivation.

    Handling and around-town performance feels a lot like my old FZR600. It's fairly responsive on the throttle, but I'm probably going to need a few more Headways to get that "yank-yer-arms-off" sensation.

    I like how the blue batteries go with the blue paint too.

    @ LarryRose11: The lower tray has four 17AH batteries (SLA) that run the 12V system. I hope to replace them with another batch of Headways someday and then use a DC-DC converter.

    @ A-bomb: It's hard to see from the pic, but the motor is blue too.

    Wow, 68ah is alot of lead for the 12v! Why so many, you only have 32ah of Headway right? I used the 120 watt DC DC converter below....it was only $35, tiny and works great.
