Default Power Wise 3 charger

After reading some of the threads related to the charger and OBC controlling the battery charging cycle on Precedent IQ carts, I was under the impression that my charger should terminate the charge cycle between 62 v - 64 v.

I started monitoring the pack voltage during the charge cycle and I'm seeing 65.3 volts at 5 amps for about the last 1.5 - 2 hrs. of the charge cycle before the charger shuts off.

Should I be concerned of over charging my batteries or is this normal?

This will be an ideal time to take individual readings of each battery.

That will give You an idea if the pack is balanced.

I assume You only have a single cable on pack negative and it goes through the OBC, right?

That voltage is fine if the OBC is doing an equalize charge.

That voltage is not fine if the reason is one or more batteries are way below the others in voltage.

10/4 on the single #4 gauge cable running through the OBC to the battery pack neg. terminal Sergio

I picked up on your recommendation in another thread that the converted and other neg. wire terminations should be on controller B- terminal, also on your and JohnnieB's recommendation on proper stacking of power wires, so I rewired my cart this week when I replaced my solenoid

I did not check individual battery voltages last night but will at my next charge cycle. I have not purchased and built the resistors and diodes battery equalization circuit you sent yet but will get around to that soon

Thanks again for your
