Purkeys’ Boss Dump Trailer Charging System is designed to keep dump trailer batteries charged and ready to use.
The Boss system works by keeping the dump trailer battery connected to the battery of the vehicle. While the engine is turned on, the dump trailer battery is constantly charging to ensure that it is operational when the driver is ready to use it.
It connects to a seven-way trailer harness and includes an LED indicator light to quickly show drivers that the system is working properly. By boosting the voltage going into the dump trailer battery, the system is designed to be effective and reliable and it is also able to keep batteries charged in cold weather.
