Paid $2000 + $150 shipping from a junkyard.
It is a work of art. I'll be sad to tear it apart for the cells, but that's life.
I'm getting 373 vdc for the battery, and 3.88 vdc per cell.

IF there are 288 cells. Already things aren't making sense. I count 72 modules about 1" thick.

I'm an idiot. Ignore module count. There are 2 - 1kWh banks, and 7 - 2 kWh banks.

It is a 96s3p pack, I have installed a BMS. I really like this pack. What I did, I used the casing of the original bms and made a board inside. Now I use the full 16kWh and the pack is still almost original. I also used the original bms connectors, very neat solution, I will post pictures soon.

I'd love to see a picture of a single cell.

Without X-Ray vision, I'm seeing 6 cell blades on the 1kWh modules, and 12 cell blades on the 2kWh modules.

I'm puzzled.

I'm going to make up words for this battery:

Blade - One of the 1/2" thick plastic carriers for the cells.

Module - Either 1kWh or 2kWh with it's own BMS connector.

Block - Two or three Modules that have their own BMS computer on top.

Advertised weight is 435lb for the entire assembly. I could not weigh it.

DOH!! Shipping weight with large pallet says 516lb on the bill of lading. So 435lb is probably right. It's a very heavy pallet.

Wow! Thanks for the link. So it's a small pouch cell. Must be thin.

Thanks. So a 32kwh pack would be right around 900 pounds.
Only if you were using the factory armor and watercooling. More than 1/2 the Volt battery assy is support hardware.

I need the weight on a single cell. I'm going to guess it's under 1 pound. So 288 lb max for the actual cells in a single battery. Could be a lot less even.

The Volt cells are very advanced chemistry, optimized for low weight at high discharge rate.

Chevy bought the licensing for the new tech from Argonne? National Laboratory.

I tried to figure out what the best LiPo's for an EV were, and I think the GM pieces were the top dog in the field.

PS - My daughter is now driving our Volt. I'm sad. :(
I love that car.
