I forget, did you have yours programmed by me? I'm one of the few places that has lithium algorithms.

If not, then there's no knowing what algorithms you have in there. I'd suggest you look in the manual for how to get the current algorithm to display.

I have the manual and datasheet on my site (which is closed, but I left things on there for informational purposes):

If you did get it programmed by me, Ned is correct, that #164 would give you 91.188V. Sounds like you're maybe on #123

The algorithms are as follows:

(note, that the same algorithms are used for 48V, 72V and 96V chargers)

Alg ID: (48V model, charge cutoff, 72V model, charge cutoff, 96V model, charge cutoff)

#67: (48V 49.2V, 72V 73.8V, 96V 98.4V)

#128: (48V 54.7V, 72V 82.044V, 96V 109.392V)

#211: (48V 55.44V, 72V 83.16V, 96V 110.88V)

#163: (48V 57V, 72V 85.5V, 96V 114V)

#53: (48V 58.392V, 72V 87.588V, 96V 116.784V)

#123: (48V 59.88V, 72V 89.1V, 96V 119.76V)

#164: (48V 60.792,72V 91.188V, 96V 121.584V)

#135: (48V 62.256, 72V 93.384V, 96V 124.512V)

#177: (48V 65.688V, 72V 98.532V, 96V 131.376V)

* = default algorithm when I return to someone

If yours was programmed by me, and it's set to #164, then you would need to measure voltage at the charger connector. There's voltage drop along the cables, so keep them as short as possible between charger and battery. If you're measuring at the battery, and your cables are 10' long and go through several connectors and different connections, then each connection is a voltage drop, and the cable has a voltage drop along it.
