Approach for charging trailered battery

An arrangement for charging an equipment battery for equipment while the equipment is being towed by a towing vehicle, the towing vehicle having a primary battery with an anode and a cathode for electrically powering the vehicle during use and having a rearwardly-located hitch at for towing the trailer that carries the equipment battery, and the equipment battery having an anode and a cathode adapted for powering the equipment, the arrangement comprising:

• an in-line circuit breaker having a first terminal and a second terminal;
• a front set of main electrical lines including a separable wire with a vehicle terminal at one end thereof for electrically coupling to the anode of the primary battery and another terminal for connecting to the first terminal of the in-line circuit breaker, and a remaining dual-wire portion with a vehicle terminal at one end thereof for electrically coupling to the cathode of the primary battery through the towing vehicle and a main plug-in adapter at another end thereof, wherein the main plug-in adapter includes a light indicator adapted to be electrically coupled to the primary battery through the front set of main electrical lines and to indicate that the main plug-in adapter is electrically coupled to the primary battery;
• a rear set of rear electrical lines including terminals at one end thereof for electrically coupling to the anode and cathode of the secondary battery and including a trailered plug-in adapter at another end thereof;
• an intermediary set of interconnecting electrical lines including a first plug-in adapter at one end thereof for releasably plugging into the main plug-in adapter and electrically coupling to the primary battery and a second plug-in adapter at another end thereof for releasably plugging into the trailered plug-in adapter and electrically coupling to the secondary battery;
• and
• an electrical continuity indicator integral with at least one of the plug-in adapters, wherein in response to the main, rear and intermediary sets of electrical lines being electrically connected, the electrical continuity indicator indicates that electric current is flowing and the primary battery charges the equipment battery.
