There are a lot of suggestions in this thread that are probably based on real-world experience and may trump this suggestion. However, the manual for the EG4 LifePower4 batteries suggests bulk/absorption to be at 56.2 (
see page 5). Take from that what you will, others will have different opinions, but that's what the manual says.
You might also make sure you have the latest firmware on your batteries and Comm Hub if you don't already have that applied.
There is a dongle that Signature Solar is giving away for free that makes this pretty simple if you haven't updated your batteries.
