Thanks for the response. I do not have much experience in electronics, so I have a question: how do I keep the charger current from passing directly to the controller (not charging the battery)?

Hey guys, I just wrote up a schematic for a 48V electric go kart I am planning to build. Before I buy all the parts, can someone make sure the schematic is correct? Thanks! - Charles Fries

Would anyone like to view/correct my schematic for a 24V system with an Alltrax controller? http://25.media.tumblr.com/tumblr_m45g8hZaBS1qkbchho1_1280.jpg Thanks!

Okay guys, I have sort of a radical idea here. After a bi of research, I discovered that standard D batteries are rated at 1.5V and 8Ah. Does this mean that I could have 32 D batteries wired in series to produce 48V at 8Ah? Also, if I created an additional 2 packs and then wired the packs in...

I have a question about my Alltrax controller. The Alltrax wiring diagram says that I should use a contactor to cut off the power supply from the controller, but my question is, can I just use a heavy duty switch, like this? http://www.cloudelectric.com/product-p/sw-20314.htm Thanks!

Hey everyone! I've been looking at this forum for a while now and I've decided that I am going to build my own electric go kart. My inspiration came both from this forum and the Neurotikart (http://www.youtube.com/watch?v=CykCx1xLEzQ). These are the parts I will be using to build my kart...

****! Those batteries are $230! You could get some Optima Yellowtops for half the price!

It is a golf cart controller. How do I wire in a port for a charger?

Hey all, My name is Charlie and I just finished the circuit for my electric go kart. I have 4 12v batteries, a 48v controller, and a 36v golf cart motor. Everything is pretty much done, I just need a way to charge the batteries. I've seen people on many forums just disconnect the batteries and...
