I haven't seen that from Trojan. I realize it's a different product line from the sizes that one would likely use in an RV, Trojan's Solar AGM line shows a 1200 cycle life at discharge to 30% SoC (70% DoD), and no one would do that every time. That's better than the cycle life of Trojan's Signature line flooded deep-cycle products. The spec sheets routinely show a cycle life at 50%, but that doesn't mean that they can only be discharged to 50%.John, I’ve looked at the various battery makers. Still, Trojan only wants you to go to 50% DOD, so only 130 useable ah’s.
I agree - discharging to 30% SoC (70% DoD) is certainly possible, and for any battery there is a trade-off between depth of discharge and cycle life. I hope that the trade-of is better for the SiO2 variant.Finally, PerryB67's plan mostly seems to be to run the dual 260 Ah AGMs to 30% discharge, and more in difficult situations. That should work just fine, but it seems a $450 pair of 6V AGMs should be able to do it.
