How To Install A Battery Isolator Relay
This is why I want to install an isolator relay which drive the current to the start batteries first up to 13.7 volts, then to the camper batteries, after that, it just deliver power to whatever batteries need power. The controller operates by sensing the voltages on both batteries. When either battery is being charged, the controller will close the isolator solenoid, connecting the two batteries together, charging them both. Anytime either battery voltage goes above 13.3 volts for approximately 5 seconds, the solenoid closes. The first step to powering up your van camper is to install secondary batteries that are charged off your van’s alternator. You want these secondary batteries to be separated electrically from the alternator when the motor is not running. You can buy fancy electronic battery isolators for prices up to and over $100.

Stinger’s SGP32 (formerly SR200) 200 Amp high current relay is the most reliable and efficient way to add secondary batteries to your system. Many people listen to their stereo without the engine running.
This often leads to dead batteries and a vehicle that won't start. This can be resolved by installing a second battery, but installing two batteries can also be a challenge. A battery isolator will let you completely discharge one battery without discharging the starting battery. This SGP32 isolator uses large high current relays to control the flow of current. The advantage of the solenoid based isolator is that there is virtually no voltage loss across the contacts.
