Great item - real time saver
This item eliminates the need to remove the battery from the boat to recharge. Now I have the battery hard-wired and firmly affixed to the boat deck in a battery box.
Quality of the item is great, it was easy to install in my boat. Seems to do a great job of maintaining the battery. Price was better than comparable items I researched. Would give it 5 stars if I had more than two weeks of use from the product. Does not come with a full product instruction manual, but I easily downloaded one for free from the company's website.

You do need ? where each wire gos to the battery as this cheap unit. Seems to work good. I have this on a small 14 alum boat. My Range has a 4 bank. I have only had it pluged in three time but seems to charge the battery. The light stays on all the time it is pluged in to 110V. Very had to tell if the battery is at full charge.

I wish to use this on my starting battery so can I add it to the battery with all of the other connections? Is this maintainer waterproof? Will the plug have to be kept dry when not plugged in? How about when plugged in?
