[Electric Boats] Re: Corvus Li Based battery .. designed for Marine Use

I purchased my cells from EV Components, who were located about an hour away from my shop. Paid my money and drove them home in my Subaru.
They are no longer in business, but here's another source:

There is no associated CALB BMS that I know of. I'm using the Manzanita Micro product, which are made about an hour north of the shop.

Here's a spec sheet for cells I have on board:

Please note that the only relationship I have with these companies is that of being a satisfied customer.
