This is a 100 Watt 500Ohm precharge resistor.  Used to precharge the input  capacitor to a DC-DC converter, controller, inverter, etc. to eliminate the sudden inrush of current.  This will decrease the charge current under 1 ampere for almost any size pack eliminating the possibility of damage.  Once the caps are charged, which takes just a few seconds, then the power can be applied safely.
