Low Voltage Disconnect
Low voltage disconnects help protect your batteries from being over drained. I use one to protect my battery bank. I like to keep the cut-off high just in case something happens I have at least half of my battery bank full. I use the low voltage disconnect by Energy Core Products, it is the only one that is user adjustable I could find.
