    3000w 72v E-Kart

    I couldn't honestly say because I have never rode it long enough to run the battery completely down. I would estimate probably a full hour of riding. Charging also takes less than 30 minutes at 8 Amps.

    It very quickly depleted the pack. It went from 76ish volts to 60 (my controller lower limit) in a matter of seconds.

    Motenergy 86v E-Kart ME1306 Build

    Yeah on the last run I bumped the battery limit up to 100 (bad idea) and quickly discharged the batteries, but still never got over 3000 RPM. And I also noticed that one cell wasn't charging correctly because I didn't add a bar between like the others so I had to fix that. I haven't really done...

    I have been waiting on the BMS for over a month now (stupid AliExpress) so I haven't had a chance to really charge the pack. I've also only done a couple short test drives and have monitored the voltage after every one so I am not too concerned with cell damage. I am going to try and charge the...

    Motenergy 86v E-Kart ME1306 Build

    Almost finished with the kart. Just needs some brake lights and maybe a windshield. I finally got around to testing with a laptop connected and found out the reason I am not reaching my expected speeds. Seems the motor is not going over 3000 RPM. Not sure what could be causing that except for...

    Thanks, I will make those changes and see how it goes. Also, could you explain the motor nominal current and what it should be set at? The user guide doesn't list this setting.

    Here are the current setttings. Let me know if you see anything that can be improved.

    Motenergy 86v E-Kart ME1306 Build

    Trying to get a closer to 60mph, I guess in theory that combo should already be close to 50. Not sure why I am not hitting that, need to hook up and monitor the controller readouts.

    First test run. The big sprocket is really reducing the max speed but I have a 46T on order.

    Overkilling the Go-Kart Again (67.2v Chevy Volt battery -> 87.6v Headway 38120HP)

    Man that thing flies! That first turn was a bit sketchy lol, thought you were for sure going to go in to the forest. And yes, FortNine is the best, watched his videos before buying my first bike.

    2 speed or dual sprocket centrifugal clutch on electric motor?

    Afla_wheels is who I actually got my 3000w motor and controller from, be careful though as the controller I received was not the controller listed. It did not have a good percent of the connectors and had no low/med/high speed settings.

    3000w 72v E-Kart

    That size probably would have worked, but it never really showed up on any of the sites when I was searching. I am happy with the size now and since wheels are not cheap I will stay with these for now. I also like the idea of the low/wide stance with no roll cage. I feel like it's would be a lot...

    Yep already planned for the amp constraints, I didn't originally plan to go so big with the motor but the cost differences were too close so I decided to just go big. I might even end up swapping over the LiPo pack from my other build as they are rated much higher.

    3000w 72v E-Kart

    The problem on the rear was finding tires large enough to give clearance for the live axles sprocket. It was surprisingly hard to find tires and rims with a large enough diameter to give it that one extra inch while also clearing the frame. It turns pretty good now after adding the weight to the...

    3000w 72v E-Kart

    Here is my first electric gokart build using a Chinese 72v motor/controller and 72v 20s2p LiPo Battery pack. Top speed is about 35 mph. Steering is a bit iffy in the front because of the un-even weight distribution (hence the weights).

    Figured I would start a thread this time to document the progress on my 2nd electric gokart conversion. Wife got me the frame off Facebook for $50 as a birthday present. It had been sitting in a field for about 5 years. I was able to get the engine running by replacing the carb with a $10 ebay...
