Jack, While the form factor of a Leaf *pack* may notbe right, inside that pack are rectangular *modules* that are easy enough to put into a different shape pack, so you *can* play with the basic "building blocks" and see if a Leaf pack would be of any use. Note that a single Leaf pack will not only give you limited range but also limited power as you cannot draw high performance current from a Leaf pack without destroying it in short order. But as a limited power prototype to get a conversion going for not much money, it can be a first step. Note that you can take 2, 3 or 4 Leaf packs in parallel and get both range and power that will be closer to your expectation, the obvious issue is to find space for those modules, that will be your biggest challenge.
BTW, NEDRA will be a great resource of how to get the power you need and do it in an EV. Also, do not get discouraged by one person telling you how *he* would approach your situation - you are in control of your own decisions and can choose your own direction, many here are doing that, some are building their own controllers. I would suggest to get in contact with people who have been working at the cutting edge and in the past have built great components exactly because someone challenged them to get unheard of performance, notably the Zilla controllers that Otmar designed. Last I heard of him, he was designing a high-power AC controller so it might be possible to use AC in your product, even though you may want to stick to DC in the prototype to get power components that are available *now*. Success and let us know how it goes!

What 2-door sports car do I start with? ;^) A hacked up 4-door Tesla is nowhere close to "exactly what you believe there is a market for". If someone wants a 4-door EV let em just buy a Tesla and keep me out of what I think is a money losing proposition. BTW, I AM starting with an existing car and modifying it. It at least has the right number of doors and already comes as a convertible. > Buy Tesla, chop off the top, and install a very nice custom convertible > (or removable hard top, or a T-top.) See how much you can sell it for to > test the market. > There are a few reasons why I do not want to go that route: 1) It's a *4-door*. I want a sports car and nowhere in my definition of a "sports car" does "4-door" fit. 2) The cost of entry is too high. I would spend my entire budget and end up with a useless (to me) 4-door convertible. 3) It's a* 4-door*. 4) I can't say "I designed it and built it". At best I get to say "I hacked up a Tesla." 5) It's still a *4-door*. 6) I don't think the market for a 4-door convertible is a good measure of the market for a convertible sports car. 7) It's still a *4-door*. 8) I already feel bad enough when I see a nice C5 driving down the road and I say "I actually hacked up one of those to do my project!" Think how bad I'd feel having hacked up a Tesla. 9) It's still a *4-door*. 10) I'd MUCH rather own my car as an ICE than a hacked up Tesla *4-door* convertible. 11) I laugh at the idiots that in the past have built *4-door* convertibles. I have no desire to be the butt of my own jokes. ;^) 12) You could be right and there isn't a market for my car. I'd rather have my car as a limited range EV than a *4-door* convertible. 13) I'm not a fan of the Tesla body style (even if it DIDN'T have *4-doors*). I'd have to rebody the thing to get what I want. Bill, I'm not saying your approach wouldn't work, but I can't see investing all that money and time building something I don't want and I don't think there would be a market for it. Then I'd be stuck with the stupid thing. Remember, I started my discussion asking if a $10k Leaf would be a good starting point. The intent there was to keep my cost of entry as low as possible for my prototype. I could buy a LOT of used Leafs for the cost of a Tesla! Luckily someone mentioned the form factor of a Leaf battery pack sucks. I didn't know that. If it won't fit between the rails of a truck frame it sure won't fit inside the confines of a sports car. Seriously Bill, I'm just looking for advice and help. But telling me to scrap my project and build what you think I should build doesn't help. -------------- next part -------------- An HTML attachment was scrubbed...
