Hi again FA, Unfortunately the custom NiCd batteries that were specific to our motor have reached end of life. So rereading through your comments a couple things to clarify. According to the formula you mentioned-Watts/Volts= Amps you estimated we'd have ~80 amp continuous draw for our...

We have a Victor 883 speed controller that uses a PWM servo tester and potentiometer as the forward/neutral and reverse. This is impractical for our go cart so would like to replace the servo tester with a Hall effect pedal. Both have same connnection of three pins, pos./neg/ signal. but...

Hi EpsilonZero, Thanks for the feedback and reference for used batteries. This will be VERY useful for future builds! As our knowledge base and confidence grows, building a battery pack is very high on the list but will require a small investment in a spot welder and a lot of reading. For now...

Ha! Nice ride! And thanks for noting the amp hours. That’s often left out of builds. Agree that would be the way to go! Just got the spindles back from the weld shop so will hopefully have some progress to post soon. Curious if you know the ballpark weight of your cart? Thanks again for your help.

Great video. That built in gear reduction you asked about is 20:1. We have a 45 tooth axle sprocket and 19 tooth motor sprocket. I wouldn't begin to know how to figure out what that amounts too. Thanks for the amp specs. We were woefully underpowered and subjected the batteries to...

We've since learned trying to measure amps on a volt meter is not accurate. That said, you are correct, they are very dead. The motor is drawing at least 80 amps; In essence we were attempting to power a Tesla with a 9v battery. :surrender:Amazing. We would need on the order of a 24 v 100 ah...

Wow guys thanks so much for the discussion here and sorry for not replying sooner. It appears notifications are off and missed these replies! Thanks Panchothedog, that makes way more sense because the assembly design would suggest it's supposed to float. We bolted the mounting bracket to the...

Interesting comments guys, thanks for the replies. This motor was previously used in battlebot competitions and was commented on that it can handle 36 v. Just wondering if this motor is too power hungry. We initially did a bench top power supply at 24 v and the max supply output of 5 amps. The...

Hi all, We have been slowly assembling an electric go cart with some gifted parts, in particular a motor, speed controller and battery. The motor is great. It's looking like we may need to go with a new speed controller too. Here's the question. We have a burly 24 v 1875w 2.5hp motor. Does...

Thanks so much for confirming that! I kind of had an idea that was it but just couldn't find anyone to confirm it. thanks!

Hi, I'm working on an electric go kart. I just got a kit with a mechanical brake disk, caliper, and caliper mounting bracket. I know you attach the bracket to your frame first so you can put the screws in and then slide on the caliper, my question is how to fix the bracket to the caliper when...

Hi all, We received a 30 volt Nimh battery pack to use on our electric cart build. We're new to all things electric so want to make sure we're charging this pack correctly. Using a bench top power supply and a Nimh specific charge controller, we're going to set the volts on the bench top...

Hi all, We are finally returning to our electric cart build. Purchasing a live axle kit from BMI Karts which includes a 54T Sprocket for the axle and a #40 chain. We now need to match the correct motor sprocket but I'm once again confused with all the chatter around the subject. We also...

Hi all, We are trying to assemble a VERY economical cart engine kit. However, Though I've read a lot I still can't figure out what would work. There are some wonderful math equations but it all looks like another language to me. So, a few questions: 1.Brushed motors are by far a better...

Hello everyone, My son and I are endeavoring to build an electric cart as our big summer project. We are novices in just about every aspect of this build but relish the challenge. Our primary goals are to build something elegant, efficient and extremely thrifty. We have not decided on the...
