Recommendations for this, it easily separates two batteries and the leisure battery charges while driving. Good if there are no solar panels on the roof. However, the car needs to have a large charger connected to the engine, but that part is fine in caravan cars. RECOMMENDATIONS+++++

The product is as described. The price is okay, but the logistics part is a bit cumbersome. The tracking of the package is non-existent.

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.

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.

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!

Does this device also automaticly separate batteries if there is no charge voltage from the generator?
Answer This Question
When the generator is not charging, it also depends on whether the voltage of the main battery is lower than 12.7V. Only when the voltage of the main battery is lower than 12.7V and it will be automatically disconnected.
