I can give a bit of data - which may or may not be useful.
First I believe there is an LVC in both the Das-Kit Controller and also in the BMS of the battery. I'm assuming that whichever one is reached first will cause shutdown. I have 3 batteries that I use on my NCM bikes. I recently did some capacity tests on all 3 by fully charging and discharging each using an external load. Here's the results regarding end voltage::
Pack Ah
Start Voltage
End Volltage
13
54.09
41.59
16
54.09
42.50
19
54.10
40.90
So the LVC for the packs seems to be around 42V.
I do not know what the LVC is for the Das-Kit controller.
