This male to male DC power cable can be used for a variety of uses. It's primarily used to charge and connect the Dynamic Perception portable power pack to the MX2 controller. It can also be used as a power bridge between the Merlin telescope head and MX2 controller so a single battery can be used for a dolly and pan/tilt combo.
