Ah....5%. Hope it sticks this time. Im fairly certain they are 170ah and most of the batteries were taking 11-12amps to maintain the 2.70v per cell.
I screwed up and fell asleep early. Woke up and one of the newer batteries had been equalizing for 8 hours. It was taking close to 17amps to maintain the 2.70v. I was expecting to see the opposite. When i first started the charge i dont remember exactly but it was between 8-12amps to make the battery voltage 2.70v per cell. I set the charger to 17amps and it tapers down to whatever it takes to maintain the 2.7v per cell.
8 hours later it needed 17amps. Whats going on with that? If the batteries got hot, should resistance go down?
Felt bad because its not my golf cart. Hope i didnt damage that newer black battery by equalizing for 8 hours.
