You can make any voltmeter (analog or digital) do the same job as a loaded voltmeter by just paralleling a load on the meter leads when you measure the voltage. Use a 10 ohm 1 to 5 watt resistor for the 4 and 5 cell batteries and a 22 ohm 10 watt resistor for 6 to 12 cell Nixx batteries. You do not need a load when measuring LiPo or Pb cells. IMHO buying a loaded voltmeter is a waste of money, you can have a more versatile VOM for the same money and have it do as good or better job of measuring what needs to be measured.
