Help Choosing Components

[Cedric]

Hello, I am hoping to get some help figuring out what drive line components I need for my AWD kart. I need help for 2 different scenarios, 2 motor (one in front, one in rear) and 4 motors (1 at each wheel). I am planing on using 4 yellow top Optima batteries however if someone has a better idea I am open to suggestions. I have 4 gauge wire and can wire it anyway needed, be it parallel or anything just so long as the motors are all connected in a single circuit to keep them all running the same. I am thinking of wiring in a similar way to the pictures posted but I just don't know what motors to use and if I need the gear box with them. I am okay with slightly overvolting it just so long as it is durable, lasts me a long time, and can be used for long periods of time (say an hour or 2). A huge concern of mine is also POWER!!!!!!! The more the better I was looking at DeWalt 26V and 24V Hammerdrill motors and gearboxes. What do you guys think?
