> 20 of these will give you 10kWh
Not really - lead acid batteries are limited to only using about 50% of their capacity, go any deeper more than a handful of times and you'll pretty much destroy it.

Please go find a good, modern lead acid datasheet and familiarize yourself with it, because I'm tired of people who've clearly not been around anything from the last decade or two parroting this line endlessly when it comes to lithium and lead.
Here's the datasheet for a GC2 form factor Trojan T105-RE from about a decade ago (I've got a 6 year old pack in my office): https://www.trojanbattery.com/pdf/datasheets/T105RE_TrojanRE...
Notice that it's rated for about 700 cycles, to 100% DoD. And about 4000 cycles at 20% DoD.
Lead has many advantages for stationary storage, and they're not the same batteries you found 40 years ago.
