A Dynamite 7.2V 1100mAh NiMH Battery pack in a mini v,

It's a 5 cell pack and the proboat pack is 6 cell, and I'm not sure if the plug(connector) is the same as the esc, is it a direct drop in still?

Is is better than the proboat pack?

And does it fit snug into where the battery would normally sit?

Thanks.
