A smart battery isolator switch allows an additional battery to be charged by the vehicles charging system, yet not be engaged in motor starting. It also eliminates the starting battery from being drained by your accessories when the charging source is insufficient, engine is off to charge both batteries.
This unique technology is a hybrid device. It engages state-of-the art
solid state technology to efficiently deal with both protection and charging capabilities.
This smart battery isolator switch is employed to manage battery systems that
charge off the alternator. Let the auxiliary power packs be eliminated by the equipment or start the car. It allows the secondary battery to be charged at the rate determined by the alternator output. To do this efficiently the correct size of cable needs to be utilized during installation. Larger lead acid batteries when significantly discharged could make use of as much as 150 amps. For this reason you should select large enough cable to handle the amps produced by your charging source or alternator.
- 4. The emergency "Jump Start" mode enables the secondary battery to
"Jump" or nourish power back to the startup process if the starting battery pack
is inactive or low. This could to give a boost in cold weather conditions or if that pesky squirrel snuck inside the cab and left the lights on all night.
The secondary battery often is a deep cycle battery isolator designed to allow for repeated charge /discharge cycles. The battery isolator switch can be used as a low-voltage cutout to preserve the car's battery from becoming drawn below 12.6 volts with no additional diodes or current sense resistors required, the model is a self enclosed dual battery isolation relay.
