Just upgraded to 6 volt
I have two Trojan T105+ deep cycles that I replaced my old 12 volt boat batteries with. Series wired, off course. I suspect I'll have more amp hours now. Question; should I do any maintenance on t...

I never think of 6 volt as being an upgrade.
Maybe, if there are substantial more AHs. Otherwise, I see a pair of 6v batteries as a negative. If one battery dies, the system is dead. If one of 2 12v batteries dies, you lose half the capacity but everything still works.
Lots of people see that a Trojan T105 6v battery has a capacity of 225 AH and fail to realize that is equivalent to 112 AH for a 12v system.
You are making it confusing. To clarify, two 225AH T-105s make a bank at 225AH. Two 110AH 12s make a bank of 220AH. Many people upgrade from a pair of 85AH 12s so they go from 170AH to 225AH with the same footprint, but the 6s are a bit taller.
and since 6v GC. at least the trojans. will last hundreds of cycles down to 25 percent SOC, a 220AH trojan bank of two has 150 useable AH. while a 220AH 12V battery bank has 110 useable AH.
I've done the 25 percent SOC on a trojan bank around 400 cycles over 14 years and the batteries are finally ready for replacement
downside of 6V is not being real frendly to high discharge rates when used with big Inverter loads, say 75A or more. If that is a big need for you, GC is not a good choice IMHO.
