Yes, you're pretty much spot on for the two 13S5P 48V batteries I built last month with the BMS's that the battery seller supplied. The cutoff is around 39V. As I'm submitting my battery order today, I've just added a 14S 20A BMS and 52V 2A charger, and I'll have the flexibility to build either 48 or 52V. As I have requested a second empty battery case, it might be tempting to use the second one to build a lightweight 21700 5A 13S1P reserve battery to carry as a backup.
Thanks for those links, I'll have a look.
