Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...

It sounds like a classic case of batteries being so low that they can't take hardly any amps at first. Usually you can bring them up in state of charge slowly and they start acting "normally" again. It can take hours and hours. Don't stop yet.
I don't know your batteries but you can get them back to normal with any luck. Your Trimetric set you astray somehow on the percent.--go by the SG--always the SG.
We can't test the new PM until you have your batteries acting properly
The PM should be a 75, they don't make a 70. If it is like the prototype I know about, it has a switch and a pot (two holes in the side to get at them) There is nothing to set when you go three stage -switch being to the left looking at it. The pot should then have no effect. You should only have been able to set that 14.7 with the switch to the right, which enables the pot.
If it does mess up the three stage, then you have an earlier version when it did. It was supposed to be corrected for the production model. With the earlier version, if you were in three stage and messed with the pot, it screwed up the voltages for the three stages. You could get out of that by unplugging and starting over with switches and pot setting, forget details, but I can dig that info up if needed. Gets complicated, but it worked on the one I saw to get out of the messed up three stage. Not supposed to happen with yours! Hmmmm.
Now I wonder if that three stage is. If you only got 13.7 when it was set to the left and amps tapered instead of increased as the way low batts came up some. Might have to put switch to the right and use the pot to get your 14.7 etc. Weird! :(
This is why they are testing them for now to get feedback before going to production, so let's see what it really does.
