In preparation for pulling my E15 apart
for R&R I decided to put a really good equalization charge on my pack
so I ran the charger overnight. I reached a max voltage of 43.4 and all
battery cells were bubbling. After I unhooked the charger and let the pack
sit a half hour the voltage dropped to 39.5, all the batteries were within
.1 volt of one another.
Still I think I have a bad cell since
after I buttoned it up and drove it to the shed the "gas gauge"
dropped a good bit from driving 150 yards. I didn't have time to check
battery voltage at that time, but is that the best way to find a bad cell,
run the batteries down some and see which battery has discharged the most?
PS I have one of those "Solargizers"
that I purchased because the shed were the tractor is normally parked doesn't
have power. While I was cleaning connections yesterday I tested output
unconnected to the pack and it was 60+V in full sun. The meter I was using
(actually a dwell meter) doesn't have milliamps so I couldn't check output
but it's very small.

You're right, that is way too low, I did a fatfinger,
Should have been
14.7 or more. I usually use a value of 2.7 volts per cell as the
The auto charging systems I worked with were set to 14.4 volts nominal
at under hood temps.
