    Steps to safely recover low voltage NCM cells?

    Hi, I have a prismatic NCM pack of 20S 92Ah 3.65V nominal cells in an electric motorbike. They have a Daly BMS set to protect them from over discharge, but somehow it didn't do that and whilst stood through winter they have run down to a range 1.8V to 2.2V.
