DEALING WITH BATTERY #6

 I have written about the poor performance of battery #6.

Watt hours = 570.78

Amp hours = 12.31

"Today's test was very disappointing. Number 6 battery has lost 28% of its original power. I knew something was not right when the battery only registered 56 volts at full charge instead of the normal 58.4 volts. This was completely unexpected. 

Should one cell in the battery behave badly (discharges too quickly) it will suffer premature voltage sag and trigger the BMS to shut down the entire battery. 

A further effect is that a cell that discharges too quickly will also charge too quickly. The defective cell reaches its peak voltage before the rest of the other cells resulting in them being undercharged."

Today I took Battery #6 and trickle charged it. I did this by charging it in tandem with two other batteries using a three headed charging device. This had the effect of reducing the charger's 4 amp capacity to 1.33 amps.

Well the charging is complete and the result is that the battery now shows 58.0 volts!

It is now 9:20 pm PDT and, in an hour, I'm going to go out on a depletion run.  I will post the results when I get home which will be about midnight. 

I would go out right now but there are hordes of flying insects out at sunset and they get in my eyes and nostrils.
