Battery Pack Sliding/Moving Inside Dolphin Case

[Jaison]

I have a 52V 13.5A Dolphin pack purchased about a month ago. It seems there's a lot of empty space inside the case and the pack jumps around and slides inside. I'm concerned about breaking a connection, etc.. My plan is to put HD foam inside to take up the space. How difficult is it to open up the case? Is it just the 5 screws I need to take out?

Mission accomplished. Just removed the screws, put some HD foam in the empty space and right back together. no need for pry tool.
