Thanks Martyn.

Hi Andrew and thanks for posting here.
Well, I received an email from a support rep. That is the reason for post above regarding the TA018.

I received a reply from my question above but I do not see it in the forum here for some reason. I understand now that the TA018 would be better for my needs. Can I ask what the significant differences are and why there is such a big price difference between the TA189 and the TA018? Again, thank you...

Hi, I am looking to find out what the minimum mA reading that the TA189 is capable of. I would like to trace the current draw on a discharge cycle of a 3.7 volt 18650 battery. The discharger will drop the load to a few mA as the battery voltage drops close to 3.2 volt stop point so I am wondering ho...
