Lead Acid Battery - 2 Cells No Float
So I picked up a new (to me) rig from family last weekend. It had been sitting at the BIL's place for several years. He started it occasionally, but never kept it plugged in. 2 of the 3 group 29,...

The higher SG (more acidic) sitting there for so long could have eaten plate so maybe not much left? If you got 1.3 up top where the hydrometer can reach, what was the SG like near the bottom all those years sitting there?--it would be higher. You might remember my tipping the 27s days to de-stratify them.
I have run mixed banks of various combos no problem while camping, then recharged them at home by type to their own specs and combo again for floating them if not enough floating chargers handy.
I have done two 6s and a 12, three 12s and two 6s, four 6s and a 12, and for lots of AH two 12v T-1275s and four 6s. Then I got two 12v AGMs and mixed them with the two T-1275s. Now I am back to four 6s in the Class C and two 12s in the TC.
I did try it without mixing batts, using one set for inverter only and the other set to run everything else. That worked with two solar sets one on each set of batts. It wasn't a good way because the "RV" set would get low and there was still plenty of AH left in the inverter's set, but no way to get at those AH to run the furnace. So back to mixed bank to spread the wealth.
What is the converter in the new to you rig?
