Specs:
Note: It is recommended that you purchase an isolator with an amperage rating above that of your alternator to prevent any damage to the isolator.
In a multi-battery system, the battery with the lower state of charge will drain power from the battery with the higher state of charge. This battery isolator protects your starting battery power so that no matter how weak your accessory battery becomes, the accessory battery will never drain power from the starting battery. This battery isolator also saves time by allowing simultaneous charging of both batteries. The amount of current flowing into each battery is determined by its state of charge, which guarantees that each battery will get fully charged, prolonging its life.

This 120-amp battery isolator enhances your alternator performance for efficient charging, maximum power, longer battery life, and safer operation. Protects main starting battery from auxiliary drain. Regulates current for multi-battery system.We always get a great product from Etra iler.
While it was a challenge to put it in our motorhome, once installed, it works perfectly. It appeared almost identical to the original one I removed on our 1996 Road Trek.
Going to give it a 2500 mile test run t omorrow.
Ordered by phone with Gwen and Stacy's help and elected to pickup the battery isolator in Wentzville, Missouri. Price was great and it has a one-year warranty. Within an hour or two they emailed it was ready. Pickup was also quick and professional. Item is an exact replacement for the 25-year-old failed part in terms of form, fit and function. Installed without rewiring or drilling and is working great! This could not have been a better experience!
Great selection and very reasonable prices, many with discounts, often cheaper than that big online site. Particularly impressed with customer service when I had a product issue, called me right away and offered replacement item immediately with free UPS return label.
Great service, just what I needed. Thank you.
All I can say is that Etrailer ROCKS! Ordered on Tuesday and got it Thursday. The only thing better is if I could’ve picked it up myself!
Thanks Etrailer for fantastic service!
Product as described. Great price and speedy delivery
Charges our auxiliary battery with no p roblems.
Haven't installed it yet. Delivery was quick and the product was what I ordered.
So far it works fine.
Prompt service and the product seems to work great
On time great service
Timely delivery arrival, very good packing job, undamaged NEW items arrived due to good customer service. This is definitely a high quality unit. The heat generating epoxy-sealed electronics are protected from overheat by a generous amount of blue-anodized extruded aluminum cooling fins. This is a good value, and it is the reason that I bought 2 of them... One for use, and another for a back-up, in case I have a shorted battery... Keep-up the good work!
The 95 amp isolator is an excellent unit. Used on my RAM 2500 diesel pickup for my pop-top camper, this unit is quite sufficient to keep both my dual truck batteries and dual camper batteries charged by my 160 amp OEM alternator. Quality gear; Highly recommended!

The battery isolator l purchased from you guys is serving me well with no issues.l don't have to worry about my starter battery running down except for unrelated reasons.
Wiring instructions left a lot to be desired
