I'm designing a power hungry robot and this is my first time constructing a battery pack. Specifically, I am going to use a 3(series) x4(parallel) 18650 battery pack using these Samsung 35E cells. The calculated max current draw on this battery pack would come out to be 32 amps. When finding a Battery Management System, should I be looking for one with a max current rating above or below(like this one) the calculated 32 amps of the battery pack?

Above obviously, otherwise you restrict the power available or damage something in use.
Also make sure you have sufficient fuses.
