I ordered 30 used A123 cells this morning. Should be here in a week. I’ve sketched up a diagram of how I can charge so many cells at the same time. I think strapping the whole thing to a 2×4 will work nicely. From the testing I did on Ray’s pack of A123’s, I think they will work great for the scooter and hopefully for the truck. This could be CNC’d and then a lid screwed on. The posts are close together. I don’t know how I’ll get a BMS board across those posts.

Here is a concept sketch of how the A123 module will duplicate the volume of a flooded nicad.
