## Description

Battery Tender 021-1162 Solar Panel Charger Controller : desertcart.in: Garden & Outdoors

Review: This has a very specific purpose. I've used solar battery chargers before that you plug into your 12V power source or directly to your battery. They haven't worked. Taking that same solar panel and plugging it into this worked. One of the key things I learned (the hard way) is that the solar panels I had did not use the Red is + standard. This unit has protection against getting your wires backwards. The power LED helped me figure that out. Once I got my wiring right this thing just worked.
Review: We use it on a static engine battery with a solar cell - works well
