Wow. Lost details. So much waste... Anyway...
I don't necessarily agree with
@Ampster on his recommendation even though his reading comprehension is insanely superior. 27V is only 3.375V/cell, which MIGHT be fine for you if you don't want to fully charge them.
Absorption is 29.2V for a full charge, If you want about ~92% charge, 27.2V
Absorption termination current = 28A
Float at 26.8V (3.35V/cell)
Rebulk at 25.2
Equalization set to something just over absorption (I think it makes you go higher) AND disabled.
Note that a lower voltage absorption will take much longer to get to 28A termination current. I tested a 0.5C charge at 27.2V, and it took 6 hours to terminate at about 92%. That same charge to 92% SoC at 29.2V took 1 hour, 49 minutes.
It takes some experimentation, but faster charges to lower SoC can be had by charging to 29.2V and then cutting off at a much higher termination current.
