Great Product

The product gets the job done. Not much to say, but when measured across the terminals, there is no noticeable voltage drop. This product (or the 200a version) is a must when more then one battery is used. It would have been nice if PAC released a protective boot for the terminals though.

Great Item

This battery isolator is the same as the more expensive brand name ones. Good idea to use when you have multiple battery systems and don't want to kill your main battery.
