I myself think that 14.4 is too low for FLA batts, I'm in the 14.8 temperature compensated camp and at a minimum the C10 rate for amperage.
Damm Mex, I wish I could type like you!!...... :B
I run true deep cycle batteries, the kind with 5% antimony plates, the kind that are considered heavy duty industrial use. Trojan's T-1275. Others have commented, and they are correct, that this particular battery is a bit of a funny or unusual one in it's charging needs.
I go with 14.8V on a Trojan T-1275, and so far, I'm pleased with the results I am getting. Good solar on top of generator and bulk charging in the AM is giving me good results. YMMV, the 6v golf cart batteries seem to do just fine on 14.4V. The T-1275 seems to like the voltage a little bit hotter to get things topped off quickly.
I'd run 14.4v to group 24 DC and group 27 DC for bulk charging. Which is what we are discussing ONLY here, in this thread. Bulk charging, that 50 to 90% "git 'er done" charging you do first thing in the morning, making noise, and burning expensive gas, while trying to minimize time charging, noise, and fuel expenses to do so. ONLY because fuel savings grow faster than the cost of getting another year or two out of your 8 to 10 year old deep cycle batteries on your part time toy hauler RV gizmo. Time is money also. Time spent burning gas charging adds up fast. Babysitting solar panels is a no brainer. Know the strengths and weakness's of both types of charging systems, and play to their strengths.
