Work has been keeping me very busy lately and away from my battery charger, so I appreciate the patience of all those who have been following this project. I recently looked through past data I had collected and found a charge plot from the same battery on the old 1.8VREF charger (although many cycles ago) to compare with the new 18-bit charger. It doesn't necessarily look like much of a difference, but it is tremendous. Now that I have it all working and have ran it through a few cycles, I am consistently getting resolution around 0.016mV. Readings from the temperature sensor have also improved (compare the temperature plot below with the one from my very first post), but I am past the noise floor of the temperature sensor (by a lot) and therefore can't improve it much more.
