Questions and Answers
1 Questions
I run a dual battery setup for my car audio system in my 2008 Nissan Altima I was worn that an isolator or relay would best be installed to prevent damage is this true?
The dual battery isolator protects the main battery from overcharging. When the main battery is full and higher than 13.3V, the isolator switch will open to charge the excess power to the second battery. When the main battery voltage is lower than 12.7V, the switch will disconnect to protect the main battery. Whether it is necessary to install an isolator is your choice.

Heavy Duty Isolator 140a
Very happy with this high quality Isolator it has a low voltage cutoff so you will not over draw your primary battery, the other side connects to my second battery or my house batteries and automatically opens a flow of current to charge them while the car is running. It has a high voltage cutoff to protect the source or car battery and alternator from being damage and at the same time protecting the house battery from receiving too much current. This solved my problem of keeping my lead acid and Lithium charged. Best investment I made in a long time.

Works great!
Ive had this in my Polaris ranger 2016 900-5 crew, for about 8 months. I have 2, 1200 Odyssey batteries installed. This thing works like a champ. It passes the charge to the battery that needs it the most. I tax my system more than most people ever will, and this isolator does more than I need it to. You have to understand your setup and how it all charges or you wont understand how this thing works. I have 2, 54in curved 4D light bars, and 2, 50in curved 4D light bars, along with 2, 7in light bars, and in cab, mulit color lights. I can run all night on my setup. I can hunt 3,000+ acres, for over 8 hours without any issues. I can hear the isolator clicking back and forth, and I can watch my voltage move around. I never drop under 10 volts, on a full load, and that is after all night of hunting. It would of been nice to have longer and better neg and pos. cables, but because of all the other work done to the Ranger, I did have better cable laying around. Others will not have the same luck. So a tip to the seller. Just give the better, longer cables. It wont cost you that much more, and honestly even if it does, I would of paid to have the better cables. Outside of that, I didn't buy this for the cables. I needed the isolator, and it is great quality, and works flawlessly.

Love it!
Installed it 4 months ago as a bank up battery for my system and aux lights. Works as it should and works flawlessly.
Pat Pat
Always out of the way and ready to go.
Used it 2 add cranking power from multiple batteries. Works like a Charm!
Bob G Bob G
Works well.
Works as advertised, turned my dual battery hookup in to a proper charging outlet for my deep cycle lead-acid battery bank. I even managed to hook up the 1 guage wire directly to the terminals of this thing lol, and it works great. It's secured to the front of my battery box right now, in the back of the van.
Michael Robinson Michael Robinson
Works great!
Solved my issues. Installed 2 ahm batteries for air bag system. When compressors kick on the voltage doesn't even flicker. Batteries are always fully charged
Troy Troy
Works great.
This was purchased to isolate an RV auxiliary battery used for starting the generator from the start battery bank for my engine. The original design had these two batteries banks connected together for charging purposes, but not isolated. Since the auxiliary battery was a smaller capacity battery it could drain the chassis battery during long storage periods leaving me with a dead chassis battery. Now with the battery isolator the two batteries are disconnected from one another unless the engine alternator, or other charging source, is supplying a charging voltage to the chassis battery. The battery isolator then applies the full charging voltage to the auxiliary battery, when needed, allowing it to recharge . Diode isolators have been used for this purpose and work ok, but they have a voltage drop across the diode which limits the charging that can occur. Diode isolators are solid state devices and can be susceptible to voltage spikes. This device is a much better solution. its rugged, delivers a full charging voltage to the load battery, and isolates the charging source battery when there is no charging voltage being applied. No dead battery after 6 months of winter storage.

Very happy with my purchas
Love this product. It charges my Garmin Livescope battery as the boat motor is running, therefore allowing me to fish longer
Chris Chris
Worth all the money !
Easy to setup. Perfect for my auxiliary 8d lead acid battery that powers the van's lights, appliances and chargers. Always enough alternator power to charge the backup no matter what the van is running.

Works great.
Took roughly 15 minutes to install this Isolator in our camper van and could not be more pleased. We were having issues in the rain keeping our batteries charged with solar and this is an amazing alternative when we drive to our next location. It is quiet and was the simplest electrical setup. For under $100 it is well worth the bonus battery charge and safety in those long rainy weekends. I have already had 3 of our friends get this after seeing it in our van, I highly recommend this to anyone who needs some extra juice or wants some safety in a backup to solar. If you drive your van a lot this would even work instead of a solar system. Great product!
