| - [[http://amzn.to/2h2tDxp|single voltage sensing]] - this type reads the voltage of only one battery. In the case of an RV it would read the voltage of the starting battery. When it is high enough above resting voltage (ie, being charged by alternator) it connects the starting and house batteries. \\ [secessus says: "IMO the practical benefit (if any) to charging the starter battery "first" is keeping the load on the alternator reasonable. In practice, the isolator generally connects the two within a few seconds."] \\ Examples: [[http://amzn.to/2h2tDxp|Sure Power 1314]], [[https://amzn.to/2tEGp1e|BlueSea BatteryLink]], [[https://amzn.to/2Ri2jQV|Battery Doctor]]. | - [[http://amzn.to/2h2tDxp|single voltage sensing]] - this type reads the voltage of only one battery.
