I think I have Chris half-convinced to do an Open Source 144V motorcycle!
We were discussing all the different possibilities of controllers - new vs. used, different voltages, amperages, and prices.
In the end, an Open ReVolt controller would fit all the criteria of inexpensive, powerful, and expandable.
Plus, if we do screw it up, it can just get popped open and repaired, unlike potted commercial controllers with their proprietary goo'ed-up insides.
Well, most likely the cycle wouldn't actually run at 144V, as that might be too much for the motor, and 12 chargers might be a little pricey as well, but a 500 amp motorcycle at 48 or 72V would still be LOTs O' Fun!
Everyone, please push Shiba towards going the Open Source Controller route. He knows he wants to....
PS - He would LOVE donations towards the project! Maybe we could push a few bucks straight to MPaulHOlmes to start paying for a controller board....
