Absolutely. It's all about the $/kWh stored. A "worn out" electric car battery might have only 70% of its cycle depth/capacity remaining compared to when it was new, but if the battery packs can be acquired for very cheap, that doesn't matter so much.
There is a guy with videos on youtube who has purchased battery packs from crashed Tesla Model S and retrofitted an old volkswagon bus for 100+ mile EV range.
