    Suzuki GSX-750 '99 conversion

    Yesterday I collected my Suzuki GSX-750 '99 bike at the motorbike shop.
    The owner took already the drive train out of the bike so I got it half price.

    Conversion is aimed at light weight and high speed.

    Parts which I'm planning to use:

    - Enertrac MHM-602 motor
    - 48s2p 16Ah Headway cells for 156V
    - 150A/300A 144V controller

    Love the look of that bike.

    Was the motor supplied with those vents in the picture?

    Yes, at first thought it was a recent modification but when I looked back at older photo's the vents were there from the beginning.

    Electric diagram v1.0

    This is my first version of the electric diagram.

    Looks pretty good to me.

    Only thing I noticed is that your DC/DC will always be on (getting input voltage) so whatever idle power it waste may drain your pack if its let to sit too long.

    Doesn't the kelly need 24V or more on the enable pin (pin 1)?

    And yeah, the DC-DC will always be on. What DC-DC are you wanting to use? Maybe it has an enable pin?

    I believe you are correct. He could just run pack voltage to that pin, just get the voltage after the contactor so the controller can be turned on and off.

    Specs of the KHB say: 8-30VDC, preferable 24V.
    After asking Kelly further, they assured me that these KHB are also working good with 12V, but they advised me 13.5V because of the little voltage sag, when using full lights, horn etc.

    The DC/DC converter i'm using is the Kelly's HWZ serie, 25 Amps.

    Yes, I'm aware of that. There is a good topic about this, and what I saw is that the idle current is quite low for such converter (didn't measure it though), but I'm going to calculate it.
