Charge profile for 12/12-30 Non-isolated

Hi, I'm need a little help setting up my charging profile. I have an Orion 12/12-30 non-isolated dc to dc charger.

The bank I'm charging is 4 x 6v deep cycle batteries connected in series and parallel. One battery is 6v, 230ah and the whole bank is 12v 430ah.

I requested the charge characteristics from the battery manufacturer and they sent me the following form:

I was going to go with the following settings but was looking for someone more knowledgeable to help me out:

Absorption voltage = 14.1
Float voltage = 13.8
Bulk charge time limit = 9.2
Re-Bulk voltage offset =0.4
Maximum absorption time = 12

The easy bit is float 6*2.25, 13.5V.

Charger has no constant current setting, but its limit is 30A, half the max for your batteries. So pretty OK.

Setting absorption voltage to 14.1V as you suggest should be OK. But up to 14.4V should be ok.
