I won't argue the point. As I said, the problem is unusual, just something to be aware of.I doubt there is any Lithium Ion battery pack out there for any remotely popular e-bike without low-voltage-cut-off. the in battery cut off may be lower that what is needed to power the bike, but it would be high enough to protect the cells.
Some overseas battery manufacturers do everything they can to keep costs down. Unfortunately, the quality of the BMS in some of these products is suspect.
Grin Technologies ran afoul of this back in 2014 with their LiGo battery line. The product was discontinued briefly due to the inferior BMS installed by their overseas supplier. The product has been redesigned and is now back on the market. Read the story here:
LiGo Batteries - Grin Products - Product Info
The LiGo battery is a modular 36V pack designed and manufactured at Grin that is just under the 100 Wh limit allowed for passenger air travel. This allows you to bring multiple small batteries with you in your carry-on baggage, and then hook the packs together to behave as a single large battery...

Two of the earlier LiGo packs I bought, died from over discharge. Grin is a reputable company and they provided a refund. I can't say enough about Grin Tech, but that's another post.
There is a reason some batteries cost $300 and others well over $1000 for the same spec. It isn't likely you will run into a LVC issue with the quality batteries provided by major manufacturers. All I'm saying is, if you buy cheap knockoffs, beware.
