Newb wanting advice

I am seriously considering building from the La Bala kit from www.grabercars.com. Excluding the cost of the chassis, can I do ~100 mile range for $10k with that platform? Thanks in advance.

I don't think so. Even with that platform you will likely need about $10k just in Lithium cells to hit the 100 mile range mark.

yeah, a car would get ~300wh/mile, maybe more, maybe less, it's "average".... so that, times 100 miles is 30kwh. Add a little more for good measure, and you're at least 32kwh, at $1.25 an Ah for CALB (lets use 100Ah cells), you'd need ~100, 100Ah 3.2V cells worth of capacity, so that's $125 each for 100 cells, that's about $12,500 for just batteries (give or take). That doesn't count motor, controller, charger, Battery Management/Monitoring, DC-DC converter, Cable, wiring, fuses, gauges.....etc.

And the enertia won't do 100mi range at 100mph, it's more like 45mph or lower to get that sort of range.

It seems like you're investing a lot of money for a long-term vehicle. After some time, you'll eventually be saving yourself money that would have been spent on expensive gas. But you're also doing the world a service.
