I have room for 7 group 29 batteries. If it will fit, I'll replace the starter battery with an SiO2 as well. That ought to leave me close to 7 kwh of usable storage.
Maybe when it is 30 above, but at -40 that will work out to about 3kwh using SIO2. still much better than 0.5kwh agm would give you at thoes temps.
