Future battery card / inverter card extra data?

I am aware a Battery card is coming, but I was wondering if the battery card and current inverter card could include hardware version info? There appears to be 3 incarnations of the 8.2kwh battery with latest version offering up to 4100w output. It would be good know the reversions for future upgrade plans. Example if a AC 5kw comes out it would be handy to know my battery will do 4100w to benefit from it etc. If version information could be shown on the cards it would be really helpful in the longer term.

On a side note if replacement products with better features did come out some kind of upgrade/discount/recycle plan would be amazing. My AC3 does what I need it too right now, but if a bigger version came out I would certainly look at it and want to plan some kind of upgrade. There must be some value to refurbing inverters? batteries?

Does the sticker on the side of it not tell you this? (not trying to be a d....maybe they've changed on the newer ones)

Gen 1 Battery (Nov 2020)
8.2 Total
80% DOD
Leaving 6.5 Usable
80A Max @ 51.2V Nominal so 4000W (can't imagine newer ones are lower amp although the datasheet at the time stated 60...)

Guess the temperature range may be of use to someone, sure I saw a post on here about cold weather.

hoggy Hmm not sure I can get to that sticker with the housing I built around my system. Mine is an external install on the front of my house, so I built a small shed/cover around it to stop anyone tampering. I will take a look over the weekend.
