Great deal. Even though I don't see what the difference in between Gen 1 and Gen 2 batteries are ... I do see they're backwards compatible with like voltages.

I got two new Gen 2 4ah batteries this year. I tested their capacities and they were lower than my 4+ year old Gen 1 4ah battery. The Gen 2 batteries do have a 4 segment battery gauge vs the old 3 segment. The Gen 2 4ah batteries are the same physical size of the Gen 1 2ah batteries.
Can't decide whether to get this or buy a whole new mower which will include one with a lot more power.
Bought the 80V 21" push mower (plus 2 batts and charger) for $380 exactly 5 years ago, and one of the batteries is JUST now really giving me problems in terms of how long it lasts.
Used this to cut .5 acre from about March to October, usually weekly. That's a pretty good testament to the durability IMO - both of the mower and the batteries. Not to mention I use the same batteries to power my blower (which really drains them). Amazing, really.
I could buy more batteries, or I could upgrade to the newer models which have lights (would love this!), more height settings (mine only has three...not nearly enough), and possibly a larger deck like 22 or 23".
That 40V mower with the included 5ah battery would be a lot more powerful than my 80V.
After more reading, the above is not true. The 40v mower would have more runtime, but would have less torque/power. I am actually much more interested in torque, since my current setup (80v/2ah batt) does not have enough blade speed to get leaves up very well and can sometimes struggle in very thick grass.

good deal. If I were you I would just buy new batteries. I bought 2 for myself
Need it one for my gen 1 mower that i have from oct 2019.My old battery still works fine but just need a spare. There are few bad reviews, some say is fake battery and others say is not returnable
How is the cooling on these? Takes so long for the Gen 1's to cool down enough to charge that in the height of the mowing season I'm rotating through 3 batteries and at times they're all dead and too hot to charge.

Put a box fan on your charger. I have two chargers and three 80V batteries and I'm never waiting for a charge (even in peak summer Florida). It also helps to swap your batteries before they run out completely because running them close to empty will generate more heat - I try to swap when they hit one bar of charge remaining.

You mean you set the charger on top of a box fan?
Just point a box fan at the charger and battery during charging. The built-in fan within the charger just needs a little help.

That's been the solution I've settled on. I have 2 chargers and 3 batteries like you and I have to swap prior to it going dead so I'm always trying to guess how long I should let one go. It's worked well lately that the grass isn't super long every week but in Spring not so much.
