 A voltage sense wire is a separate wiring circuit running from the battery bank to the controller's voltage sense terminals (if so equipped).
-Since the circuit isn't carrying any real current there will be very little sag and even quite thin wires can be used to get an accurate voltage reading.  The controller will then adjust output voltage to put the desired setpoint voltage into the bank.
+Since the circuit isn't carrying any real current there will be very little sag and even quite thin wires can be used to get an accurate voltage reading.  The controller will then adjust output voltage((up to some max, like +1v or +2v)) to put the desired setpoint voltage into the bank.
 Example:  The absorption setpoint (Vabs) is 14.0.  The sensed battery voltage is only 13.8v, so the controller actually puts out 14.2v.((or whatever it takes to get 14.0v at the battery))
