2 Lithium Batteries Failed

Traveled only 40 miles and battery pack was weak driving home. Charged the pack and today tested each battery. See chart of numbers. Number 41 and number 44 in the center area were Zero volts with the other 45 rest voltages running from 3.34 to 3.68. I have only 2 spares left so will rotate them into…

28 Thousand EV Miles

The Saturn has been holding up fine the past year or two. I did have to replace the controller a few months ago in July 2015. I had a used spare one I picked up earlier. Otherwise it has been trouble free 2015. Now coming up it looks like the  sensor/relay for the vacuum pump is…

Charger and Battery Pack Problem

Low Battery Event

This evening I had a Struggling Saturn as I rolled the last 5 miles with reduced power. My dash voltmeter has failed and I have not replaced it yet so I cannot record the voltage results nor did I have the cell log connected. Running through each battery and testing the results at rest are…

CellLog 8S First Logs and Thoughts

CellLog 8S Cell Voltage Monitor & Logger [[http://saturn.lynnautorepair.com/node/518|I installed the CellLog]] a couple of days ago. I logged 7 of the 48 CALIB 130 amphour LiFePO4 batteries both while driving and again during a charge cycle. The log data is very impressive and informative. When I first opted to go to the CellLog I had…
