All of the electrical power required to operate the trailer brakes is drawn from the trailer
mounted brake battery. It is critical that the trailer brake battery is a “deep cycle” battery, and has a minimum capacity of 17 amp hours. Operation with a weak or discharged battery can cause the actuator to malfunction, resulting in possibly serious or fatal injuries and/or property damage. Do not attempt to operate the unit if a low voltage condition is signaled.
