These numbers seem a bit out of whack, maybe a typo? I am surprised a cart will even move at 40V. Per Trojan discharging a 48V pack voltage to less than 46.63 (20% SOC) will do serious harm to the pack. I do everything I can to never discharge my packs to less than 48.4 (50%).

Couple of links folks should read and understand:
