Turbo3 (LeafSpy) had indicated that the Pro versus would have a feature to measure the battery resistance as in the Tesla app (TM-Spy)

and in the LeafDD (Leaf parameter app). To date it appears that the feature is not yet available in LeafSpy. Here are data from my 2013 Leaf

which provides one an idea of how battery resistance is affected by temperature, age, & SOC:

11/20/14 -13,700 miles, 76 mohms per LeafDD, 20 Deg, 73% SOC

11/30 - 13,900 miles, 56 mohms per LeafDD, 27 deg, 71% SOC

12/2 - 14.100 miles, 55 mohms per LeafDD, 28 deg, 67% SOC

10/5 - 39,300 miles, 100 mohms per LeafDD, 22 deg, 50% SOC

10/6 - 39,400 miles, 61 mohms per LeafDD, 30 deg, 51% SOC

10/7 - 39,500 miles, 80 mohms per LeafDD, 25 deg, 56% SOC

10/15 - 40,000 miles, 71 mohms per LeafDD, 27 deg, 45% SOC

10/30 - 41,000 miles, 74 mohms per LeafDD, 23 deg, 66% SOC

12/26/16 - 43,000 miles, 110 mohms per LeafDD, 13 deg, 77% SOC

6/10/17 - 49,600 miles, 89 mohms per LeafDD, 19 deg, 70% SOC

7/1/17 - 51,000 miles, 62 mohms per LeafDD, 33 deg, 44% SOC

8/15/17 - 53,400 miles, 61 mohms per LeafDD, 35 deg, 57% SOC

4/2/18 - 62,100 miles, 110 mohms per LeafDD, 18 deg, 94% SOC

6/13/18 - 65,000 miles, 84 mohms per LeafDD, 26 deg, 52% SOC

8/13/18 - 67,000 miles, 80 mohms per LeafDD, 26 deg, 91% SOC

9/14/18 - 68,000 miles, 84 mohms per LeafDD, 27 deg, 57% SOC

10/30/18 - 70,000 miles, 93 mohms per LeafDD, 22 deg, 84% SOC

11/9/18 - 70,000 miles, 104 mohms per LeafDD, 22 deg, 89% SOC

11/30/18 - 70,400 miles, 88 mohms per LeafDD, 23 deg, 88% SOC

12/6/18 - 70,800 miles, 116 mohms per LeadDD, 13 deg, 33% SOC

1/30/19 - 72,300 miles, 86 mohms, per LeadDD, 23 deg, 45% SOC

A very basic resistance test of the 2018 Leaf indicated that it had a similar resistance value to 2013, i.e. it was expected to have a lesser value

given the higher capacity.

#1 Leaf SL MY 9/13: 74K miles, 48 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 - 100% > 1000, temp < 95F (35C), min discharge (DOD) > 20 Ahrs

#2 Leaf SL MY 12/18: 115 Ahrs, 5.5 miles/kWh (average), Hx=98, SOH=99, DOD > 25%, temp < 105F
