Hi AJ. Nice to see you are back at bringing us more battery information. My 4 year old T875 batteries finally gave out and I too purchased new T890's instead of trying to convert to 8, 6volt batteries. The reason, too much weight and cost of converting.
I bought the T890 in August, it did take a few charge cycles before I suddenly noticed a difference in power. All went well for a few weeks and I began to notice the cart was slower and lacked power. I started checking individual voltage, pack volts etc. What I found was under a load, one battery would drop from 8.5 volts to 3.7volts. The rest would only drop to about 8.2. I took the battery back and had it replaced under warranty and all is good now. After a full charge my individual volt readings are 8.51. Like you I’m hoping the 890’s will give longer life, I was told by the dealer I should get about 5 to 6 more miles per charge but I really don’t want to run them down far enough to find out.
Sometime I’ll run into you and show you the Datel Digital pack voltmeter.
