My car plan is from scratch, entirely my fabrication. A 10 kwh pack will weigh around 160 lbs with lithium batteries, they have 4-6 times the energy density of lead acid and NiCd batteries.

Yes you can split a pack up so long as you wire it properly, and many all electric cars do this.

The wheel hub motors I want are made by BluWav. They have all wheel drive communication built in, regenerative breaking, ABS, traction control and disc breaks in each wheel hub. I do not know the cost of them at the moment, I would guess anywheres between 1500-5000/wheel but I dont think they are availible to consumers, only to manufactures.

If you are converting a car, you can expect the car to weigh between 2000-3000 pounds completed, if you use light lithium ion batteries, other wise expect 4000 pounds. Additionally the car should be equiped with low rr tires, and I would completely redesign the exterior to drastically improve the aero.

Converting a car would probably require up to 50kwh pack unless you significantly reduce weight and drag, and would only get maybe 50 miles range without those improvements. It is likely far cheaper to cut as much weight and drag as possible to reduce the need for an expensive battery pack.
