Hi, I’m currently working on converting a gas go kart to an electric go kart for a school engineering project. This is my first time working with go karts and I just got a klipper go kart off of facebook marketplace. My budget for batteries is about 150 and I’m hoping to use a 3000w motor. Do you have any tips and/or batteries you’d be willing to sell?
@TexasNEV Жыл бұрын
@@santa3k732 Unfortunately, $150 for the battery necessary to power that motor properly is not possible. However, you can get 6 12v 7.2 aH Mightymax Lead acid batteries for $20 each at Lowes.. It'll work but you'll have little to no range and it won't dump the current necessary, but it'll get you a passing grade for your engineering project. I have some other ideas that will cost a little bit more but won't kill your budget either so contact me at info@texasnev.com if you'd like more help.

Latest update, we converted to a more easily changeable adaptable T8F chain and sprocket combo that originally came with the kit. This, in addition to the upgraded Lithium Iron Phosphate battery has yielded a top speed of 40mph (up from 32!) with a quieter ride to boot! Super fun and super fast! Completely serviced with a 90 day warranty as this go kart is for sale on e-bay.

Is it correct that you had you system hook up to the battery while charge to 82v without any problems? I saw 80v on the picture of your battery indicator.

Initially it was a repurposed used stack of 5 64 aH Nissan Leaf cells converted from 2s2p to 4s, which theoretically made it 20s @ 32aH. One single cell failed, and I ended up dismantling and selling the pieces and made a brand new 24aH Lithium Iron Phosphate battery which was 24s3p with 8aH cells from BatteryHookup. The battery worked amazing and the cart could hit 45 WOT but it was obvious it was overvolted. :) All else being equal, it would have been best to make it a 24s4p (32aH) So I would recommend any 72v lithium battery with a continuous discharge of 50 amps in a 30-40ah range and you'll have a ball.

Hey Randy I'm doing a build with an 48V 1800W motor, 18AH SLA batteries and ordered a 50 tooth sprocket to make a 5:1 gear ratio too. I really wanted to do this instead of 6:1 to ensure that my kart goes fast but I'm worried about overloading the motor and heating/frying it. I bench tested my previous motor order for 5 minutes and it got so hot the insulation started melting (I think that's what the burning smell was). That was probably a defective product which I returned, but I want to be cognizant of keeping the motor cool (relatively speaking). How cool is yours and how long do you usually run it for? I intend to go for around 30 minutes. I saw online that it's possible that motors get stressed when they are run below full rpm, but hopefully its okay with the 3 speed switch. Finally mine is a good deal weaker than your motor, not sure if you can speak to this but do you think at this gear ratio that it'll be the deciding factor? Sorry, loads of questions, but props for a great project and explanation videos
@TexasNEV 3 жыл бұрын
When it comes to heat, it's all about the current not necessarily rpm.. The RPM ratings are based on no load. Part 1 details the go kart speed calculator on BMI karts, try that and see what #'s you come up with. If you get unusually high top speed calculations, the 5:1 ratio may be too much, but then again, it depends on the weight of the kart and driver as well. If you get 30 min of hard running seems about right for a motor to get hot. It is always better to start out with a higher tooth count and work your way down. FWIW 6:1 is pretty standard. If you melted a motor on the bench (w/ no load) in 5 min it was either defective or miswired. The speed controller should have kept your current at or below the rated level, so that's weird.
@ritwikdixit6799 3 жыл бұрын
@@TexasNEV The calculations show 31 mph. I see that yours is a 2 person kart and mine is 1 person, I'd estimate it would weigh 300 lbs with a passenger inside. Regardless, the controller is rated 33A, which is 88% I get from dividing the motors wattage by its voltage. So hopefully at 5:1 gear ratio, that works out. I was looking at forums on electricscooterparts.com, and they said that gear ratio should be fine for that power. I just wanted to check the intuition with someone who had done the build already.

If I power it up very high it keep skipping about every 10 seconds. I have it on a 4 wheel bike with 24" wheels, overall weight with me on it is about 370lbs. It goes faster than I want to go, the bike has no suspension, I've had it up to 25mph, but I'm afraid that loud clicking sound is causing damage to something. I'm assuming it's the chain jumping the sprocket on the motor 11 t sprocket. My shaft sprocket is 50t.

Archimedes once said "Give me a lever long enough and a fulcrum with which to place, I can move the earth". Same goes with sprocket size and gear ratio.. :) If the total weight is 330 lbs and you have no expectation of high speeds and use a sprocket big enough, sure. Note I just hit 38 mph in this go-kart (my son hit 44), I weigh 210 and the go kart probably weighs about 75 lbs.. So the question is, how fast do you want to go? Note that 3000w is about 4 hp, and if your tire size can support a large rear sprocket (70-80 tooth) then that could be up to 32 ft lbs of torque. What kind of buggy is it?

@@marcellange814 Hi Marcel, if it is the same motor as this, that is a little surprising. Just as an FYI, if any 2 of the 3 motor wires are touching, the EMF generated by turning the shaft will encounter a LOT of resistance. Even with the motor not connected to anything. :) It's kinda cool. However once it is connected to the controller we did not experience much of any resistance. It will be hard to find a freewheel that can take that kind of torque but by doing so, realize that you'll lose the ability to go in reverse. One thing I want to clarify is that with these bundled controllers, the e-brake is NOT a brake, all it does is cut power to the motor. It does not "brake" anything. Now, however, I'm sure that there are controllers out there that do that. These don't. The purpose of the e-brake is "emergency", not "electric". This is in case of a runaway controller (controller stuck at wide open throttle). It is a safety mechanism.

What if you run a go cart torque converter?
@TexasNEV 2 жыл бұрын
I think it would be worse. Electric motors are about 90% efficient, which is far far higher than a gas engine and give 100% max torque at 1 rpm (figuratively speaking).

@@macbook802 It has to make sense first. :) It's a nice idea but a TC is designed to help a gas engine have it's torque optimized at more rpm ranges other than its primary power band. in an electric motor, the entire range is it's power band.

What sort of speed do you think is correct?

We actually found that we had a faulty throttle pedal. After replacing it and the other modifications in the post below, my son hit 44mph in it. If you got caught up on the updates on the other videos and still think 44 mph is too slow, then I would suggest watching part 1 in it's entirety to understand the math behind the speed calculations done on BMI Karts website "go kart speed calculator".

@Bigpimpin9393 The technical specifications of the motor, current, drive sprocket, driven sprocket and wheel diameter, it is not possible. The efficacy of clutches on electric drive systems are subject to debate, and cannot make speed all by themselves. Some people have confused the brake band has a clutch in these videos.

@@itaechannel2149 If you have any configuration information for that, I'd like to see it. I can see the potential for 60kmh (37mph) if it was a bike but not seeing how it is possible in a go-kart with this motor / controller / battery setup. The total weight with rider is probably close to 200 pounds and 32 mph is about 52 kmh which is pretty close. Again a 40 tooth sprocket resulted in high heat and excessive battery drain, which means the load is too much for the motor.

Well since we changed over to the Lithium Iron phosphate, it was a little less than when we had the Nissan Leaf cells but 2-3 hours is what we experienced after the battery switch. The nice part is that there is still room in the battery box to go to 30-40ah. I sold this go kart last month and the customer said it was a "very well built and designed" go kart. I also sold the Hammerhead NEV as well as the Schwinn, and the Fat Tire Bike conversion. I have two more projects that I am working on... Stay tuned!

If you can find a junk frame or a non runner to convert to electric that'd be the quickest route. There are sooo many videos out there for DIY go karts.. If you watch the full series you'll see that I just found a junk frame. Now that I know how to weld, I may do a scratch one.. For something completely radical and insane, check out my Terminator Chopper on my channel. that was 100% scratch.
