I disassembled another battery, supposedly from a 2016 car...

Inside I found the older type (as far as I know) bms boards...does anyone know of multiple revision boards used at the same time? or have I bought an older battery...

What brings the next question, does anyone know where a production date can be found and read?

The modules have aluminium side 'guides' where others have plastic:

And it had a pyrofuse:

There will be some date codes on the chips on the cell monitoring boards that may help rule it in as a late model.

Also on the Tesla Motors Club forum there is a thread where folks are tracking the model numbers with vintage and serial number, i.e. 1091441-0-E, so a search there may help put it into which quarter of the production year it was made.

That's the first tesla pyrofuse i've ever seen and they were never even discussed a couple of years ago when i spent more time following those cars. i lost interest after spending time helping crack CAN id codes, then the factory realized what people were doing and they changed the codes.

Is that the pyrofuse after it has blown?

Yes, I made a separate post about it just now.

Looking at the pyrofuse date stamps, the battery pack couldn't be earlier than a November or December 2015 vintage, so car may have been sold as a 2016 model.
