1. What charge profile did DPI and/or East Penn tell you to use?
2. There appears there may be a mixture of terms here. (Using the word "float" and "12 hours" in the same sentence.)
Float typically refers to the voltage while float charging. Should be about 52.53V for a 48V DPI Accusense in float charge.
12 hours is the typical rest time given cart batteries to obtain the At-Rest voltage for SoC estimates. The At-Rest voltage for a Trojan class battery is 50.93V.

I haven't been able to find a Voltage vs SoC chart specifically for Deka batteries, nor a charger profile for their golf cart batteries.
What I have found id charging recommendations for their batteries used in solar applications, which are also deep-cycle wet-cells.
That document reccomends 2.40-2.45 VPC (volts per Cell) for the Absorption charge phase and 2.30-2.35 VPC for the Float charge phase.
DPI Mode-2 (Trojan) is 2.35VPC in the Absorption phase and 2.19VPC in the Float phase.
You might be better off in Mode-3 (Exide) which is 2.40VPC Absorption.
