That looks very nice.

For my car my calcs show I could reduce the pack weight by about 1/2, compared to the Nissan Leaf modules I've got.
Nissan leaf based pack - 2p, 180S, 28.35kWh, 675V nominal, 754lbs
Enerdel pack 2p, 180s, 21.0kWh, 657V nominal, 356lbs

The tough things with the Leaf pack -
Each module contains 4 cells in a 2p 2s configuration. They are difficult to dissassemble, so you're stuck with the module configuration. In order to get the right voltage, I must make a pack with "too much" capacity. Although that's not a bad thing, it results in considerably more weight.

Making some bus plates would be very easy - there's a local shop with a laser cutter that could make them for very little. In fact, a "mirror image" design would only require 1 part (less set-up cost) for both jobs.

Is that Enerdel plastic cell clip?
If so, it's designed to hold 2 cells, right?

What's the weight of 1 cell pair and a clip?

And seriously - I'm very interested - it would drop the finished weight of my car by 300lbs!! - what's the price for a cell and clip?

Thanks a bunch,
