I have embarked on a project that is a little more complicated than I intended (like most are). I designed and fabricated a "go-kart" frame that fits a 50L cooler on it with room for 2 people to sit on. After doing some preliminary research, I purchased a 1000W 36V motor and (3) AMG 12V 35ah batteries wired in series. I realize I am on the heavier side of things (about 450 lbs fully loaded), but thought this set-up would get me by. I have seen people use similar set ups on seemingly larger vehicles. Boy was I wrong. The motor spins up real nice when suspended in air, but when the tires hit the ground, it barely moves. Even unloaded with just the weight of the frame and myself standing on it (about 295 lbs), I have to, very slowly, twist the throttle to get it moving or else the motor stalls out (makes noise but doesn't spin). The set up has a decent top speed on flat ground, once moving, but ANY type of incline kills it and heats up the controller and motor. This is my first electric build, so I am 100% lost with all of this, which is why I am here. So, to my question, am I missing something with this motor/battery set up, or is it just simply underpowered? Feel free to ask any clarifying question if more information is needed. I am about to purchase a 3000W 72V motor and 72V lithium Ion battery pack, thinking my set-up is just underpowered, but didn't want to waste my money if I was missing something. I am not looking for anything to take me 40 mph (though I am not opposed to it) but some acceleration would be nice, and to not die on the slightest of inclines. Any suggestions or advice would be much appreciated.
Thanks!
Thanks!
