My plan is to use this on my camper battery to maintain it.For now I have testing this on my waverunner battery I pulled from winter storage to charge and maintain it. It has done a great job at this and floats the battery at around 12.9vThe manually adjustable Float, low voltage cutoff, and recovery voltage settings are great for customizing to your needs. This charge controller has presets for lithium, lead acid (open or vented) and AGM.

This is a very very basic charge controller. It is very inexpensive. However, you should pay a little more to get more information on your charging and more settings. I tested with two 100watt panels in parallel.Pros:* Accepts PV voltage up to 50V so you can connect two panels in serialCons:* Very basic interface.* Has no status indication of charging amperage.* The PV voltage is displayable but not documented (I found out by accident).* You can only set float voltage, no setting for bulk voltage.

As backwards as this will sound, Im glad I ordered 2 if these so I could see they are both defective in different ways. One doesnt recognize my solar panels, the other does. The usb port doesnt work on the one the solar panels work on. These are going back. I want to warn people about these before anyone else has same problem before they have the hassle too.
