+100 KW at the Nissan HQ QC only a mile away (for free) from me was the selling point I wanted.
Battery capacity and energy are measured in kWh, not "KW/H".
if you charge at 50 kW * 1 hour --> 50 kWh came out of the wall. Multiply the units and the numbers. 50 kW * 2 hours --> 100 kWh
kW/h doesn't make much sense in your context. It could make sense if you had say a megawatt power plant and you were talking about how many hours it would take to ramp up from 0 to 1 megawatt output.

Current market average price is $137/kwh, at least according to the article below, putting the price of a 62 kwh battery at $8500, plus labor, possibly above the price point consumers are willing to pay?

Price/KWH: https://about.bnef.com/blog/battery-pack-prices-cited-below-100-kwh-for-the-first-time-in-2020-while-market-average-sits-at-137-kwh/
Even if someone could buy cells in the quantities needed for that $137 per kWh price and they actually were of the proper specs for the application (e.g. safety, energy density, chare & discharge rates, can withstand automotive needs in terms of temperature swings, vibration and shock, etc.), there's the work that might be needed to qualify the cells. Then, there's the issue of assembling them into packs and the parts associated w/that + engineering work that would be needed for a BMS (to replace or spoof what's inside the pack).
I believe https://www.mynissanleaf.com/viewtopic.php?t=17470 is what's inside the pack and what Nissan calls the LBC (Li-ion Battery Controller).
There'd need to be all sorts of validation and safety testing of prototypes, pre-production and whatever stages are needed to achieve production of saleable hardware. Then factor in other stuff like liability, lawyers, technical writers, training, support, procedures, warranty reserves, etc.
