I want a secondary battery to make use of some gadgets without compromise the main battery. Battery Isolator / Relay Installation Instructions Stinger is a Power Brand of AAMP Global 15500 Lightwave Drive, Suite 202 Clearwater, Florida 33760. NVX BIR500 500 Amp Battery Isolator 500 Amps at 12V Continuous 700 Amps Surge Switching Power: 10 - 16 VDC (29) 64. The purpose of this setup is the usual one among the car and audio hobbyist. Microprocessor-Controlled 500 Amp, Dual Sensing Smart Relay Battery Isolator This product is temporarily out of stock. This item: Smart 200 Amp Heavy Duty Battery Isolator Solenoid & Relay With Switch 115.48 Sanuke Wire Lugs Ring Terminal Connectors 10 Pack-1/0Guage-3/8' Ends Heavy Duty for Battery Cable Lug Wire Electrical Eyelets with 3:1 Dual Wall Adhesive Heat Shrink 11.20 (1. I am missing something simple af and I don't know what. Wire the breaker on the supply side of the close to the solenoid. I am missing something? Is this not a relay as i know it? Or it is a solenoid? Should I add a switch to control the relay?Īs an example, here is a mounting diagram. You will also want a thermal breaker, breaker cover and a in line fuse. Then when I turn off the power, relay should change again and charge (but no, because the alternator would be off) the other battery. If I'm not wrong, this will make the relay change it's state when I turn the car on, charging just one battery. Smart electronic battery switches are a good solution for charging more than one. Most of the instructions wire 12v directly with the relay coil. A diode isolator consists of two diodes with their in- puts connected. While the instructions are clear and mount the batteries to it doesn't look like a problem, I'm puzzled. A battery isolator is a device that typically runs between a starter battery and a secondary battery. They look like simple big fat spdt relays. There are a lot of ready to deploy products in this line, most of them looking like this. Wanting to avoid the voltage drop and heat issues of diode isolators, I started to check mechanical isolation (relay). Doing some research I came across the two main techniques to do this, both based on isolate the two batteries being fed from same alternator to avoid charge issues. I want to make a dual battery setup on my car.
