Per the star trek wiki and some referencing of the TNG Technical manual:
Escape Pods (also known as "Autonomous Survival and Recovery Vehicles" or ASRV on Starfleet and Federation spacecraft) are launched from specialized bays beneath retractable sections of hull plating. These sections were spaced about the ship, providing access for as many crew members as possible. The typical ASRV is a six-person craft capable of sustaining survivors for up to eight months. (*
Eight-person versions were also said to exist) Both types were equipped with impulse microthrusters and emergency subspace comm systems; however, without a warp drive, survivors were reliant on larger ships for ultimate rescue. There also appears to be at least one phaser strip on the outer hull of the pods.
So, on a ship the size of
Cerberus, let's say that we can get 6 people per ASRV.
Kind of minimal info I know but, hopefully, gives you something to work with.
