T-125 (6v) vs T-1275 (12v)
Mex has been explaining the diffs between 12v and 6v deep cycle batts in recent threads, but there are still questions. With two of the 6s (66 lbs) that is 132 lbs for 240AH (20hr- 12a), while tw...

What is best in a house battery seems to depend on how closely your typical draws are to the battery's 20 hr rate.
Two T-1275s-, 300AH = 15a rate
Two T-105s--, 225AH = 11.25a
Two T-125s--, 240AH = 12a
Two Trojan L16E-AC, 370AH = 18.5a
Before you calculate the cost per AH, you need to line these up using Peukert. Mena must have done this, but what would be the AH for his L16s at 11 or 12a rate? More than 370.
Then you need how many batteries of each size comes to the same AH at that rate, then compare the costs of those batteries per AH.
