Stinger SGP32 High Current 200-Amp Battery Relay & Isolator for Most Vehicles, Water-Resistant Design for Marine & Powersports, Handles up to 500A Surges, Dual Battery Isolator for Car Audio Systems

This high current 12V relay was used to add a 2nd battery to my Malibu Response Inboard Skiboat (See attached schematic). A. Wiring and Installation: With the addition of: Heavy Gage Starter Cables, Silicon Diode, White LED, LED Resistor and SPDT Switch; two AGM Sealed LeadAcid 12V Batteries were installed in the battery nook of the boat. The compact LED assembly and Switch was mounted on top of the Relay. The Relay was secured to the battery bulkhead with Stainless Steel screws. B. Operation: The switch provides two operating Modes: 1-Ignition, 2-On. 1. The default condition is with the switch set for IGNITION operation. When the boat's ignition is activated via the key, the 12V ignition wire activates the relay and adds the 2nd battery in parallel to the primary. This supplies 12V power when the ignition is turned on for starting and accessories. Both batteries are also in the boat's charging circuit. The LED lights up when the relay is engaged. 2. The 'On' switch condition is available to provide power from the 2nd battery continuously. The LED stays active. The 12V source for the Relay Solenoid is the 2nd battery. C. Application Notes: 1. The main advantages of using an isolator for the dual battery configuration are: a. A leaky, bad or discharged backup battery cannot drain the primary when the boat is idle. b. On my boat, most of the accessories will drain the battery if the dash switches are left on. If the primary battery is completely discharged, the engine won't start. Switching to the 'On' position will tie in the backup battery and should provide enough power for boat operation. 2. I used my older battery as the primary and a new one as the backup (secondary). This ensures that the healthier battery will be available when needed. 3. The benefits of this setup are: a. Provides extra starting current for my V8 Chevy Vortec. b. Doubles the number of AmpHours available to run accessories.

I have had continuous problems with my 2004 Yukon battery dying, as the vehicle sits more than it is used and seems to have a significant power draw from the electronics and aftermarket radio install. GMC and Chevrolet offered a second battery as an option, and the tray is available aftermarket online. I purchased the Stinger SGP32 200 AMP Battery Relay Isolator and Relay, and took it and my backup second battery to Broadway Auto Electric in Lemon Grove for professional installation. Now my Yukon starts very strongly every time, and I don't have to worry about getting stuck at the most inopportune times. The Stinger SGP32 200 AMP Battery Relay Isolator and Relay keeps the second battery out of the phantom draw when the car sits, and uses both batteries to start the car when the ignition switch is turned on. I could have wired it and installed it myself, and if you deal with auto electronics and are familiar with such things this would be a very easy install. I would recommend the Stinger SGP32 200 AMP Battery Relay Isolator and Relay for similar applications.

I installed two batteries in my truck and I needed this. It was very easy to set it up came with instructions so installing was not a problem it did extend the life of my batteries by keeping in separated. It wasn’t expensive and a voltage range always kept it around 14.1 V when the alternator was put out 14.3.

Great

Everything works great, my initial installation purpose for this install was add a second battery while I fixed a parasitic draw having the second battery isolated from the system to back it up. It will not work that way wired per instructions, it needs too many volts from the ignition source to turn on, it wouldn’t turn on with 10v to allow the charged battery to enter the loop. To be fair this could be remedied with a toggle switch, but now that I’ve fixed the draw I’m changing the application for audio so this won’t be a problem anymore.

I actually haven't gotten around to installing this yet, but I know alot about this item and it is very high quality. The purpose of this item is to make it so only one battery is depleted, and one is reserved for starting, in dual battery set-ups. This is very common in cars when people play their music, or what have you, off of one battery, while the other battery will remain fully charged for starting. Install is pretty simple. The two smaller posts require a TRUE 12v ignition source (12v even when starting the vehicle) and a ground. The larger two posts are for your positive "battery to battery" connections. My attempt at a typed diagram would look something like this: .......................................o--------------- true ignition 12v source+ Battery1+---------------- O O -------------------Battery2+ ...............Ground(-)-------o (Sorry please ignore the dots before the top and bottom of the diagram.) *I would recommend using 0ga-4ga wire for the battery to isolator connections, and 16ga-18ga for the ignition source and ground to isolator connections. This is because lower gauge (thicker) wire has less resistance per length (measured in ohms) than higher gauge (thinner) wire. When you try to send a high amount of current through a wire that is too thin, you will generate alot of heat in that wire, which can melt wires, cause short circuits, start fires, and be potentially very dangerous. The instructions are pretty straightforward. I would recommend this to anyone running a dual battery setup regardless of if they plan to play alot of music or not. This is because batteries have different voltage potentials, which over time can drain each other trying to stabilize (but that's a very simple explanation).

Great product for the price

Very good high quality isolator it functions very well.

ممتاز جدا وسريع -:- طرفين صفر وطرفين فضي -؛- الاصفر الايسر الى موجب البطارية الرئيسية -:- والايمن الى موجب البطارية الاخرى -؛- الفضي الامامي هو مشترك في السالب في البطاريتين او يوصل في هيكل السيارة -:- الفضي الخلفي ضروري يوصل مع اي طرف موجب في إي جهاز في السيارة يعمل مع دوران المحرك ( تشعيل السيارة ) مثل راديو مكيف . شكرا

Perfecto

Super Vearbeitung, und selbst mit Reserven für Lasten von bis zu 250A ohne Probleme. Klemmen sind via Feingewinden und Federringen, akzeptabel gegen eigenständiges Lösen geschützt. Anzuggeräusche sind o.k. Relaiskontakt benötigt lediglich knapp 1,5A (keine Laborbedingungen) und alles im allen, sehr zu frieden mit dem Relais.

كنت محتار ماذا أفعل وعندما وجدت هذا المنتج بعد بحث طويل طلبته خلال 15 يوم وصل ويعمل بشكل جيد

This worked perfect for my dual battery setup In my 97 Yukon super easy to install and seems like a solid good quality product. Much better price than anything i could find locally and itll handle all the power I'll ever need it to. Using for about a month and no issues.
