    Electric goKart for SCCA solo2/autocross

    Ok guys, here is an update of where I'm at. I pulled the trigger and went ahead and ordered a conversion package that Carl over at EVdrives put together for me right at $900. Here is what just came in today. Mars me0909 motor Alltrax's new SPM 48300 controller. curtis PB6 throttle box MZJ...

    Electric goKart for SCCA solo2/autocross

    Ok guys one more question for you. Even though this Kart will be a 48 volt system, I'm thinking it would be nice to go ahead and get a 72 volt capable controller. Now if I do this and get the 72 volt contactor plus precharger & diode will I still be able to run the system at 48 volts using a...

    Check my math here please.... Battery sizing question

    Thanks guys. For some reason I kept second guessing myself last night when trying to work out the calculations. I've gotten so used to my current power setups in my RC planes that I don't really have to think about it anymore when I'm trying to find a battery for those. I do leave myself a...

    Check my math here please.... Battery sizing question

    Just want to double check if I have my math straight here as I'm trying to decide just how much battery I need for my kart project. I'm thinking of going with the 6s1p 8000 mah Zippie batteries on HobbyKing and buying enough to make 12s2p for 16000 mah or 16AH pack. So with this pack I could...

    Electric goKart for SCCA solo2/autocross

    That is essentially what I do with the Corvette on hoosier race tires. Run them at 32psi front and 28 rear for an autocross, and about 4-5 psi lower if doing a track day. And you are correct active tire warmers are not allowed in SCCA autocrossing. However, tire blankets to help retain the...

    Electric goKart for SCCA solo2/autocross

    Now that is an interesting find. Do you know of any threads were people have used that setup? 55A on the controller seems a bit hard to believe. My RC planes are pulling 40 to 50 amps and those don't have near the loading that this 1500W motor and controller would be seeing with a kart that...

    Electric goKart for SCCA solo2/autocross

    I did look into forklift motors, but way more weight than I want to put on a kid kart chassis. Also, probably way more torque than a 9 year old should have starting out. Actually that's a nice find. $199 seems reasonable, although the 80amps continuous is worrisome. Having no good idea of...

    Electric goKart for SCCA solo2/autocross

    Unfortunately the Agni motors are just not in my budget at the moment. I'm trying to approach this build as an alternative to the current gas karts so spending $2000 for an Agni + Controller just doesn't make sense when a World Formula motor can be had for $1000. I want to be able to go back...

    Electric goKart for SCCA solo2/autocross

    Hi all, I'm new to these forums and hope this is the proper location for this post. I'm looking into building an electric kart for my 9 year old daughter to use in our local SCCA solo Junior Kart program and hoping to tap into the knowledge base here. My current plan is to use the following...
