Mini Cim torque in brake mode?

We're looking to use two mini cims to drive our tote lifter mechanism. We've verified that we have enough torque with a 10:1 gear ration to lift. We're including a spring to help hold some of the weight.

We're having trouble finding the torque rating of a mini cim in brake mode. We're wondering if we can just stop the motor and have it hold the stack of totes in place or will we have to include some kind of mechanical brake to help. We'd rather not have to rely on a PID loop to actively hold the lifter at a particular position as this will be more of a draw on the battery.

Any other suggestions are, of course, welcome.

Thanks for the help.
