"Anyway, this has been pointed out several times, but the same claims still get made. In general, if you want cheap then go with flooded lead acid, if you don't want maintenance, go with AGM, if you want the best lifetime value and performance go with LiFePO4. If for some reason it is really important for you to charge at -37C then go with SiO2"
The OP just wants more AH in the battery space available than he gets now with his Wets. Li and SiO2 will do that.
As will plain old AGM, for much less money than SiO2. I cannot see any reason to go with SiO2 in this application, but they seem to be recommended for
every application.
