Game changer
Game changer. I have two 100amp batteries that I thought I was getting a good charge and management out of what I had. I learned quickly that this is a necessity.

Package missing important wire
Can I give it zero stars? Let me give this Renogy DC - DC Battery Charger zero stars, please. I wasted plenty of money on this charger, which was stated to include IGN Signal Wire, but which did NOT include the wire and I absolutely need it for my smart alternator. I didn't have a chance to work on install until after the product return window was closed so I didn't realize I had gotten a raw deal until too late, and I have no recourse. I have searched for aftermarket or accessory IGN wires but they don't seem to exist, even from Renogy. Due to the package NOT containing all of the items it was supposed to, this product is 100% unusable and a total financial loss.
