For its Roadster upgrade package, Tesla will reportedly use LG Chem as a supplier.

This is according to Seeking Alpha which in a brief report stated this and little else.

Tesla has relied on Panasonic 18650 cells for the Model S, and Seeking Alpha does add the LG deal could give Tesla leverage in dealing with Panasonic.

In related news, GM reported it is getting a sweetheart deal of $145 per kilowatt-hour for its LG Chem cells – a disclosure which reportedly upset LG Chem which charges others more and was dismayed that GM divulged the formerly secret price it had negotiated.

As it is, LG Chem is to supply GM products, and if reports are correct, it may also supply the Nissan Leaf.

Now, we can add Tesla Roadster to the list as it continues work on its Gigafactory.

These manufacturing arrangements would involve collaborative agreements where the automakers make finished battery packs based on LG’s products.

The Roadster 3.0 upgrade involves a $29,000 outlay for a new 70-kwh pack with increased energy density.

It still is not compatible with Superchargers but could breath new life into an aging Roadster.
