Yes. The cable allows you to connect a compatible external 12 V battery kit to the receiver, providing an alternative power source for extended field sessions. This is particularly useful when operating a base station for long periods and you want to reduce reliance on the receiver’s internal battery.

The cable features a 5-pin connector for the Hemisphere receiver and a trailer-plug adapter for connecting to the external battery system. Before using it with an alternative power source, make sure the battery setup has a compatible connection and supplies the appropriate voltage.

No. The package includes the Hemisphere S631 / S321+ / S321 power cable only; the external battery kit is not listed as included. If you need an external power source as well, you will need to obtain a compatible battery kit separately.

No. This product is designed to connect the receiver to an external power source. The separate External Radio Cable also includes a connector for compatible external radios, allowing power and radio connections to be handled through a combined cable setup.

An external power cable is useful when a base station needs to remain operational for an extended period without relying solely on its internal battery. Connecting a compatible 12 V battery kit can simplify power management at remote job sites, construction projects, and other locations where regularly accessing the base station is inconvenient.
