Hmm, looks like we've got another build about to happen. Cool!
==============================================
Day 13 (8-9-2019) of the Lithium Ion 2002 Club Car DS
DAY SEVEN OF THE FIRST FULL CHARGE
PERFORMANCE AND RUN-TIME RECORDING
The Li Ion batteries were fully charged on 8-2-2019, with a final voltage of 57.0 volts. Data is being recorded each day to see how the batteries perform until they are discharged to about 48.3 volts, which is the sensible lower limit for good battery life.

=================
I missed the minimum voltage target of 48.3 volts, and instead went 2 volts lower to 46.3 volts. I will analyze the data tomorrow when I am fresher and try and present some thingp useful data. I think the voltage fell off a cliff at the end of the test
Still more to come!
