definately recommend
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 perfectly
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. 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!
DITA DITA
Great value. Fast delivery.
This is a top quality product and has everything you need to setup a dual battery. Saves you from depleting your main starting battery when running other devices so you wont be stranded. Built-in voltage monitoring. Highly recommend this product.

Thank you great seller
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.

No Problems Yet! Was exactly as advertised.
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

Does what I needed it to
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.
